Chemistry Lab Equipment

Blow Pipe (Product Code: SLE/BL/13) is a nickel-plated brass laboratory blowpipe with a curved end, used to direct a fine, hot flame onto a sample on a charcoal block during dry tests in chemistry laboratories. School and college students use it for the charcoal block reduction tests of qualitative salt analysis and simple mineral identification. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Key Details

What Is the Blow Pipe Used For?

It is used for the charcoal block test. A little of the powdered salt, usually mixed with sodium carbonate, is placed in a small cavity cut in the block. The tip of the blowpipe is held at the edge of a luminous burner flame and the user blows gently and continuously, bending the flame onto the sample. Holding the tip just outside the flame gives a reducing flame, while pushing it slightly into the flame gives an oxidising flame; students then note any coating on the charcoal and whether a metallic bead forms.

Continuous blowing takes practice: breathe through the nose and use the cheeks as a reservoir so the flame stays steady. The curved end lets the flame be aimed downwards onto the block while the user keeps a comfortable distance, which is why the blowpipe remains standard chemistry lab equipment for school salt analysis. For hygiene, give each student their own blowpipe or wipe the mouthpiece with alcohol between users, and let the metal tip cool before putting it away.

OEM Manufacturer

ScienceLab is the trading name of Jain Scientific Equipments Private Limited, the OEM (original equipment manufacturer) of this blow pipe. It is made at the company's own licensed factory at Saha, Ambala, Haryana, India, rather than bought in from a trader, and goes factory-direct to schools, colleges, institutions, dealers and importers.

Because the maker handles every order itself, a repeat class set or a replacement for a lost or damaged pipe is simply a matter of asking us. Read more about the company on our company profile.

A-Shape Retort Stand Base (Product Code: SLE/CH/01) is a heavy cast iron base with an A-shaped footprint that forms the foundation of a retort stand, keeping clamps, rings and glassware steady on the bench. The base is finished in blue paint, sits on rubber feet and has a 10 x 1.5 mm tapped hole to receive the support rod. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, for school, college and research labs that need a dependable retort stand for lab work in India and abroad.

Specifications

Typical Use

The wide A-shaped footprint resists tipping when a flask, condenser or separating funnel is clamped away from the rod. Screw the rod firmly into the tapped hole, then add boss heads and clamps from the bottom up, keeping the heaviest load over the base rather than beyond its edge. The shorter rod suits routine filtration, burette work and heating over a burner; the longer rod gives headroom for distillation set-ups or when two clamps must be stacked.

The rubber feet protect bench tops and reduce sliding on smooth laminate. Wipe off chemical splashes promptly to protect the painted finish, and check that the rod remains tight in the thread before each practical session. Combined with a clamp and boss head, the base becomes the standard lab stand clamp boss head arrangement used in most chemistry and physics practicals.

Acid Rain, Weathering & Erosion (Product Code: SLE/CH/02) is a classroom activity kit in which student groups expose naturally occurring and construction materials to an acidic environment and compare them with the same materials kept in ‘normal’ rain, represented by tap water. It links chemistry with environmental studies by showing how acidity speeds up weathering and erosion. The kit is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, as an environmental science kit for schools that want a structured, group-based practical.

Key Details

Typical Use

Acid rain harms aquatic ecosystems and land areas, and it attacks both natural surfaces, such as the rock faces of mountainous regions, and man-made ones. Stones and metals used in buildings, statues and monuments can be affected, and the rate of weathering and erosion rises quickly as the rain becomes more acidic. This kit turns those ideas into an observation-based practical: each group sets up an acid sample and a tap-water control side by side, records the starting appearance of each material, and returns at intervals to note fizzing, dulling, pitting, colour change or loss of surface.

The student copy masters give a ready worksheet for recording observations, and the teacher’s manual supports planning and discussion. With materials for 15 groups, a full class can work in small teams at the same time, which makes it a practical chemistry experiment kit for middle and secondary classes studying environmental chemistry, rocks and corrosion. Follow the manual for handling the acid, have students wear eye protection and aprons, and keep the tap-water control untouched so the comparison stays fair.

Supplier

Jain Scientific Equipments Private Limited, which trades as ScienceLab, is based in Ambala, Haryana, and supplies teaching kits and laboratory apparatus to schools and colleges. Find out more on the company profile.

Alloy Test Tube and Thermometer Holder (Product Code: SLE/CH/03) is a chrome plated alloy holder with spring-loaded jaws that close on test tubes or thermometers from the smallest sizes up to 25 mm. The spring action grips without the user having to keep squeezing, which helps students hold glassware steadily and keep their hands clear of heat and chemicals. Made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, it is a practical piece of chemistry lab equipment for schools in India and for college teaching labs.

Specifications

Typical Use

The most common job for this holder is gripping a test tube while its contents are warmed over a flame, for example when dissolving a salt, observing a decomposition or checking for a gas. Grip the tube near its mouth, tilt it slightly, point the open end away from everyone and move it gently through the flame so the liquid heats evenly. Because the jaws are sprung, the tube stays secure even when a student adjusts their hold. The same holder can steady a thermometer while a reading is taken from a beaker or tube, keeping the bulb off the glass wall.

The chrome plating resists everyday splashes, but it is still good practice to wipe the jaws after use and let the holder cool before storing it. Check that the spring closes firmly before each session; a weak grip on a hot tube is a hazard. For whole-class practicals, many schools issue one holder per bench along with a rack and brush so each group has a complete heating set.

Atom Activity Model (Product Code: SLE/CH/04) is a transparent, durable plastic model that lays out the structure of an atom — the nucleus, the protons, neutrons and electrons that make it up, and the electron layers around it — in a clear graphic form. Because it is transparent, teachers can place it on an overhead projector and show the whole class the same diagram while they build up an explanation. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, as an atom model kit for chemistry and physical science lessons in India and overseas.

Specifications

Typical Use

Teachers typically begin with the nucleus, pointing out protons and neutrons and using the proton count to explain how the atomic number identifies an element, and then move outward through the electron layers so students can see the order in which the layers fill. Comparing the number of electrons with the number of protons demonstrates electroneutrality; discussing what happens when an electron is lost or gained then shows how an ion forms and how its charge is worked out. The same layout supports a comparison of ionic bonding, where electrons are transferred, with covalent bonding, where they are shared.

On an overhead projector the transparent body lets the whole class follow each step, which works well for introducing the topic before students attempt worksheet problems. As a chemistry teaching kit item it also suits small-group revision, where students take turns using the model to explain atoms and ions to each other. Store it flat and clean the plastic with a soft, dry cloth to keep it clear for projection.

Manufacturer

The model comes from Jain Scientific Equipments Private Limited, known by its trading name ScienceLab, an Ambala, Haryana company that develops teaching aids and laboratory apparatus. Read our company profile for more.

Aflatoxin meter (Product Code: SLE/CH/05) is a bench instrument that works on the solid-phase enzyme-linked immunosorbent assay (ELISA) principle to measure the aflatoxin B1 content of samples quantitatively. Used together with an aflatoxin B1 kit, it serves food, feed, edible oil, dairy, pharmaceutical, beverage and wine testing laboratories, as well as teaching labs that cover food safety. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, within its range of analytical lab instruments for India and international markets.

Specifications

Typical Use

Aflatoxins are toxic compounds produced by certain moulds on crops such as grains and oilseeds, and B1 is the one most often monitored. In an ELISA test, the prepared sample extract and kit reagents react in antibody-coated wells; after the washing and colour-development steps set out in the kit instructions, the meter reads the colour intensity at 450 nm and converts the absorbance into an aflatoxin B1 concentration. With a measuring range of 0.05–1 ng/ml (ppb), the instrument is aimed at trace-level screening, and a throughput of 20 pieces per hour suits routine batches in quality-control rooms.

For reliable results, follow the kit’s sample-preparation and timing steps closely, use calibrated pipettes, and run the instrument within its 5–35 °C operating temperature on a stable 220V supply. Because other kits can be used for other toxins, the same meter can grow with a lab’s testing programme. Food microbiology lab equipment set-ups in colleges and feed mills often place this meter alongside a balance, mixer and pipettes so that sample handling and reading happen at one bench.

Manufacturer

ScienceLab is the trading name of Jain Scientific Equipments Private Limited in Ambala, Haryana. The company is a registered MSME enterprise (Udyam UDYAM-HR-01-0003714), and its export orders are shipped under Importer-Exporter Code AAECJ8618A issued by the DGFT.

Apparatus Melting Point (Product Code: SLE/CH/06) is an electrically heated instrument for finding the melting point of solid samples packed in capillary tubes, covering temperatures from ambient to 350 °C. Its ergonomic design puts safety and ease of operation first, which makes it well suited to school, college and university teaching labs where students check the purity and identity of organic compounds. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, and forms part of its chemistry lab instruments supplied across India and abroad.

Specifications

Typical Use

A finely powdered sample is packed into the closed end of a capillary tube, which is placed in the heating block beside the thermometer. Students can use the rapid heat switch to approach the expected value quickly, then turn the control knob down to a lower setting so that the temperature climbs slowly through the melting range. Looking through the lens, with the tube lit from behind, they note the temperature at which the first droplet appears and the point at which the sample is completely liquid. A pure compound melts sharply over a narrow range, while an impure one melts lower and over a wider range, which is why the test is a standard step after recrystallisation.

The rear background selector helps with samples that are hard to see: a dark background suits white crystals and a light background suits coloured ones. Ceramic insulation keeps the outer casing cooler than the block, but the heating area should still be treated as hot until it has cooled, and a cooling plug (available as an accessory) can speed up turnaround between students. Keep the block clean of spilled powder and store the unit in a dry place when not in use.

Manufacturer

Jain Scientific Equipments Private Limited, trading as ScienceLab, is an Ambala, Haryana manufacturer of laboratory instruments and apparatus for education and research. Our company profile has further details.

Autoclave Basket (Product Code: SLE/CH/07) is a stainless steel basket with 3 mm diameter perforations that holds glassware, media bottles, instruments and waste bags inside an autoclave during steam sterilisation. The perforated walls let steam circulate around the load and allow condensate to drain away, while the basket makes it easy to load and unload hot items in one go. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, in five diameter and height combinations to suit different chambers used with an autoclave sterilizer in India and overseas.

Specifications

Typical Use

In microbiology, pharmacy and biology labs, the basket is loaded on the bench with the items to be sterilised — loosely capped media bottles, plugged flasks, pipette containers, instruments or waste in autoclave bags — and then lowered into the chamber as one unit. After the cycle, the whole load lifts out together, which reduces handling of individual hot items. Leave space between items so steam can reach every surface, avoid packing the basket tight to the rim, and mark loads with indicator tape so sterilised and unsterilised items are never mixed up.

Choosing the right size matters: the basket diameter must be smaller than the chamber opening, and the height should leave clearance below the lid. The smaller 210 mm and 220 mm baskets suit compact vertical or portable units, while the 380 mm and 480 mm versions are intended for larger chambers. Stainless steel tolerates repeated steam cycles; rinse off spilled media and dry the basket after use to keep the perforations clear. Microbiology lab equipment buyers often order two baskets per autoclave so one can be loaded while the other is in the cycle.

Three Prong Swivel Clamp (Product Code: SLE/CH/08) is a dual-adjustment laboratory clamp whose three PVC-covered fingers close around round and irregularly shaped objects, from flask necks to condensers and odd-shaped apparatus. Its jaws open to a maximum of 64.8 mm (2-9/16 in), and a wing nut on the shaft lets the clamp head rotate through a full 360° so glassware can be set at exactly the angle a set-up needs. Made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, it is everyday chemistry lab equipment in India for school, college and research benches.

Specifications

Typical Use

Three fingers centre a round object better than two flat jaws, which is why this style of clamp is chosen for the neck of a round-bottom flask, a distillation head or a condenser. Because the two adjustments work independently, the clamp can be closed evenly around a tapered or irregular item rather than pinching it on one side. The 360° swivel is useful when a condenser has to slope downward to a receiver or when a flask must be tilted for a reflux or a gas-generation set-up; loosen the wing nut, set the angle, then tighten it before adding liquid.

The PVC-covered fingers cushion glass and reduce the risk of cracking, but they should be tightened only until the item is secure — over-tightening is a common cause of broken necks. Keep the covered fingers away from direct flame, and check the rod grip is firmly locked on a rod of up to 19 mm before hanging any load. Paired with a sturdy stand, it gives students a steady set-up for distillation and other assembled apparatus.

Manufacturer

This clamp is from Jain Scientific Equipments Private Limited, whose laboratory products carry the ScienceLab name and are made in Ambala, Haryana. More about the company is on the profile page.

• A-Shape Retort Stand Base — a heavy base for building your own stand.
• Distillation Apparatus — glassware that benefits from an angled, cushioned grip.
• Retort Clamp Four Finger — an alternative with four fingers for a different grip.
• Table Clamp For Rods — fixes a rod to the bench edge when a base will not fit.

For more clamps and supports, see Chemistry Lab Equipment.

Frequently Asked Questions

How wide do the jaws open?
The maximum jaw opening is 64.8 mm (2-9/16 in).

What rod sizes does it fit?
The clamp post holder grips rods up to 19 mm (3/4 in) in diameter.

Can the clamp be angled?
Yes. Loosening the shaft wing nut lets the clamp rotate through 360°; tighten it again once the angle is set.

Will it scratch or crack glassware?
The fingers are PVC covered to cushion the grip. Tighten only until the item is held firmly.

Can it be used close to a flame?
Keep the PVC-covered fingers away from direct flame and very hot surfaces; clamp glassware at a cooler point such as the neck.

Adjustable Clamp Holder (Product Code: SLE/CH/09) is the connecting piece that fixes a laboratory clamp to a support rod of up to 5/8 in diameter, and it can be swivelled and locked at any angle so the clamp can point up, down or sideways as the set-up demands. It has an enamel finish and is tightened by hand with plastic thumb screws, so no tools are needed at the bench. Made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, it is a basic building block of school chemistry lab equipment in India and of college and research support stands.

Specifications

Typical Use

On a retort stand, one side of the holder grips the upright rod and the other holds the shaft of a clamp, a ring or a burette clamp. Slide it to the working height, tighten the rod thumb screw, insert the clamp shaft, then swivel the clamp to the angle you need and lock it. The ability to set any angle helps with condensers that must slope, funnels that need to sit over a receiving flask, or clamps that must reach across to a second stand.

Plastic thumb screws are comfortable to turn and allow quick changes between experiments; tighten them firmly but without excessive force. Before hanging glassware, give the clamp a gentle tug to confirm it will not slip. The enamel finish protects the body from routine splashes — wipe it dry after use, and replace any holder whose thumb screws no longer hold, since a slipping clamp is a common cause of broken glass.

Pendulum Clamp (Product Code: SLE/CH/10) is a sturdy stand-mounted holder with an all-steel bracket from which up to 3 pendulums can hang at the same time without wobbling. Each pendulum holder has its own knurled thumbscrew and locking device, so the cord of one pendulum can be lengthened or shortened without disturbing the others. The bracket fixes to a support rod through a rod clamp tightened with a large knurled knob. Made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, it turns an ordinary retort stand into simple pendulum apparatus for school and college physics and general science labs.

Specifications

Typical Use

The classic investigation is how the period of a pendulum depends on its length. With three holders on one bracket, students can hang bobs on cords of three different lengths, set them swinging through small angles and time a fixed number of oscillations for each, then compare the results directly. Because each cord locks separately, one pendulum can be re-set to a new length while the other two stay exactly as they were, which saves time and keeps a controlled comparison. The same set-up shows that period is almost independent of bob mass when lengths are kept equal, and it can be used to demonstrate coupled or resonant pendulums.

Mount the rod clamp high on a stable stand, tighten the knurled knob firmly and make sure the bracket is level before measuring lengths from the point of suspension to the centre of each bob. A rigid, wobble-free bracket matters because any movement of the support changes the swing and spoils timing results. After use, release the cords, wipe the steel bracket dry and store the clamp with its thumbscrews loosely fitted so they are not lost.

Fisher Clamp (Routine Improved Model) (Product Code: SLE/CH/11) is a double burette clamp that holds two burettes securely in a vertical position on a single support rod while leaving the full graduated scale of each burette visible for reading. Its all-aluminium cast mount fits rods of 1/4 in to 1/2 in diameter, and the ends carry a sleek enamel finish with rubber finger grippers that cushion the glass. Made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, it is a practical burette clamp for India’s school, college and quality-control titration benches.

Specifications

Typical Use

Holding two burettes on one stand is useful in several ways: two students can titrate side by side from one set-up, a teacher can run a demonstration titration next to the student burette, or a back titration can be carried out with one burette for each solution. Fix the mount on the rod at a height that lets the burette tip sit just inside the neck of the conical flask, press each burette into the rubber fingers and check that it hangs truly vertical before filling. Because the clamp leaves the scale uncovered, the meniscus can be read at eye level along the whole length of the burette.

The rubber grippers protect the glass and stop the burette from rotating when the stopcock is turned. Rinse any spilled reagent off the enamel ends and the aluminium mount, and inspect the rubber fingers from time to time — hardened or cracked grippers should be replaced before they let a burette slip. As part of a titration kit for schools in India, one double clamp per stand makes efficient use of bench space in crowded practical rooms.

Thermometer Clamp (Product Code: SLE/CH/12) is a stand clamp made specifically for supporting thermometers, built from a polished aluminium muff with brass clamping jaws. The jaws can be rotated and locked at any angle, so a thermometer can be held upright in a beaker, angled into a flask neck or positioned beside a distillation head. Made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, it keeps thermometers steady and hands free during heating, cooling and distillation experiments in school, college and research labs.

Specifications

Typical Use

Many temperature experiments go wrong because the thermometer rests on the bottom of the vessel or is held by hand. Clamping it lets the bulb sit in the middle of the liquid, clear of the hot glass, for cooling-curve, heating-curve, specific heat and rate-of-reaction work. In a laboratory distillation apparatus set-up the thermometer bulb must sit level with the side arm of the still head; the rotating brass jaws make it easy to set this position and lock it, even when the stand is not directly beside the flask.

Grip the thermometer on its stem, away from the bulb and scale, and tighten the jaws just enough to hold it — glass thermometers crack if squeezed hard. Slide the muff onto the stand rod, adjust the height so the bulb is immersed to the right depth, then fix the angle. After use, wipe the brass jaws and the polished muff to keep them free of chemical deposits, and store the clamp dry.

Boss Head, With Detachable Attachment (Product Code: SLE/CH/13) is a multipurpose aluminium section boss head whose phosphorus bronze clamps can hold objects either vertically or horizontally, giving more flexibility than a fixed-orientation boss. A brass-headed, nickel plated steel thumb screw and a plated wing-shaped nut secure a range of detachable attachments such as thermometer holders and suspension hangers, and the boss head is available with a thermometer hanger. Made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, it is a versatile lab stand clamp and boss head component for physics and chemistry benches.

Specifications

Typical Use

A boss head is the joint between a stand rod and whatever needs to be held. With this model, the same boss can carry a rod or clamp shaft at right angles or in line, and the wing nut lets attachments be swapped without removing the boss from the stand. A physics teacher might fit a suspension hanger for a spring or pendulum experiment in one lesson and a thermometer holder for a heating experiment in the next, using the same stand each time.

Tighten the thumb screw firmly on the rod before hanging any load, and fix attachments with the wing nut until they no longer turn. The phosphorus bronze clamps provide a springy, corrosion-resistant grip, while the nickel plating on the screw resists rust. Keep the thread clean and free of chemical residue, and store detachable attachments together with the boss so the set stays complete for the next class.

Universal Clamp (Product Code: SLE/CH/14) is an adjustable laboratory clamp whose jaws close around round objects from 9.5 mm up to 35 mm in diameter, holding them firmly on a stand while an experiment runs. Teachers, lab assistants and students use it when one clamp has to take test tubes, burettes, flask necks or glass tubing without swapping hardware between practicals. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, as part of our school chemistry lab equipment for institutions in India and abroad.

Specifications

Typical Use

In a school or college practical, the Universal Clamp is the part of the familiar lab stand, clamp and boss head assembly that actually touches the glassware. It holds a boiling tube over a burner, steadies a delivery tube during gas collection, supports a condenser or thistle funnel, or keeps a burette upright during titration. Because the jaws rotate and lock, the clamped item can be tilted to the angle a procedure needs — useful for heating a test tube at a slant or aligning a side arm with a receiver.

For best results, tighten the jaws only until the glass is held without slipping; over-tightening is a common cause of cracked tubes. Keep the clamped object close to the rod where possible, and use the clamp’s reach only when the setup genuinely needs the extra distance from the stand.

Manufacturer

This clamp comes from Jain Scientific Equipments Private Limited, a company based in Ambala, Haryana, that trades under the ScienceLab brand and supplies laboratory apparatus to schools, colleges and distributors. Read our company profile for more about the business and its product range.

Related Chemistry Lab Equipment

Items usually ordered with a universal clamp to complete a stand setup:

• Boss Head, With Detachable Attachment — joins the clamp to a vertical rod at the working height

• Thermometer Clamp — holds a thermometer beside the clamped apparatus
• Table Clamp For Rods — fixes a support rod straight to the bench edge

See the complete Chemistry Lab Equipment range for more stands, clamps and holders.

Frequently Asked Questions

What sizes of glassware will the Universal Clamp hold?
Any cylindrical object from 9.5 mm to 35 mm in diameter. Items outside that range need a different clamp, such as a three-prong model for wider vessels.

Can the jaws hold a tube at an angle?
Yes. The jaws rotate and lock in any position, so a tube or funnel can be set vertical, horizontal or anywhere in between.

Is a boss head needed to fix it to a retort stand?
In a standard stand setup the clamp is attached to the rod through a boss head. Our listing does not state that one is included with the clamp, so please confirm the supply scope through our contact page when ordering.

How should the clamp be cared for?
Wipe off any acid or salt splashes after the practical, keep the tightening thread free of residue, and store clamps dry. Avoid forcing the jaws beyond their range, which can strain the mechanism.

Micro Burner (Product Code: SLE/CH/15) is a small gas burner with a narrow 9.5 mm burner tube and an overall height of just 100 mm, giving a compact, controllable flame for close-range heating. It suits students and technicians who need a gentle flame for tasks such as flaming inoculating loops, warming small samples or bending thin glass tubing. Produced by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, it is a practical addition to microbiology lab equipment and school chemistry benches alike.

Specifications

Typical Use

A micro burner earns its place where a full-size Bunsen flame would be wasteful or hard to control. In microbiology practicals it is kept beside the work area to sterilise loops and needles and to flame the mouths of culture tubes. In chemistry, the low profile lets it sit under small apparatus, while the smaller flame is well suited to flame tests, gently warming a watch glass or softening narrow glass tubing.

Turning the air regulator changes how much air mixes with the gas: open it for a hotter blue flame, close it down for a softer, visible flame that is easier to see on a busy bench. As with any chemistry lab equipment that uses gas, check the tubing for cracks before each session and keep paper and solvents well away from the flame.

Manufacturer

The Micro Burner is manufactured by Jain Scientific Equipments Private Limited, trading as ScienceLab from Ambala in Haryana, India. Our company profile gives an overview of the business and the laboratory ranges it produces.

Related Chemistry Lab Equipment

Products that go with a micro burner on the same bench:

• Bunsen Burner Tubing — connection tubing from the gas tap to the burner
• Bunsen Burner — a larger 12 mm tube burner when a bigger flame is needed
• Micro Bunsen Burner — an alternative small-flame burner from our Burners range
• Bunsen Burner Kit — a kit option for equipping a heating station

More heating and support apparatus is listed under Chemistry Lab Equipment.

Frequently Asked Questions

How is the Micro Burner different from a standard Bunsen burner?
Its burner tube is 9.5 mm across and the unit stands 100 mm tall, so it produces a smaller, more localised flame than a full-size Bunsen burner and fits under low apparatus.

Which gas does it run on?
Our product documentation for this item does not specify the gas type. Tell us whether your lab uses LPG or piped natural gas through the contact page and we will confirm suitability before you order.

Can the flame be adjusted?
Yes, the rotatable air regulator lets you change the air-gas mix, moving the flame from a soft luminous flame to a hotter non-luminous one.

Is gas tubing included?
The listing covers the burner itself. Tubing can be ordered separately, for example our Bunsen Burner Tubing.

How do I keep the burner working well?
Let it cool before handling, brush away soot or spilled material from the tube opening, and keep the painted base dry so it does not corrode.

What about warranty?
We confirm warranty terms in each quotation; contact us for details that apply to your order.

Can you supply a full lab or an overseas distributor?
Yes. We supply micro burners in class-set and wholesale quantities across India and to international markets.

Bunsen Burner (Product Code: SLE/CH/16) is a routine-heating gas burner built around a 12 mm nickel-plated brass tube, with a threaded needle valve to set flame intensity and a rotatable air regulator to shape the flame. It runs on either natural gas or LPG, so the same model can serve labs with piped supply and those using cylinders. Manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, it is a standard Bunsen burner for schools in India, colleges and training laboratories.

Specifications

Typical Use

This burner is the everyday heat source of a chemistry practical: boiling water in a beaker on a tripod and gauze, heating solids in a test tube, evaporating solutions to crystallise a salt, and running the dry tests and flame tests of school salt analysis. Biology and physics classes use it too, for warming water baths or demonstrating heat transfer.

The needle valve is what sets this model apart from a basic burner. Students can open the valve a little for a small, steady flame or further for vigorous heating, while the air regulator switches between a yellow safety flame and the hot blue cone. The serrated inlet helps tubing stay on during use; push the tubing well over the serrations and inspect it regularly for cracks.

Manufacturer

Jain Scientific Equipments Private Limited produces this burner under its ScienceLab trading name at Ambala, Haryana, and supplies it to educational and research buyers. Learn more in our company profile.

Related Chemistry Lab Equipment

Useful companions for a Bunsen burner heating station:

• Rubber Pipe For Bunsen Burner — flexible gas connection from the tap to the serrated inlet
• Burner Bunsen With Stopcock — a version with a stopcock for complete gas shut-off at the burner
• Bunsen Burner with Flame Stabilizer — an alternative when a steadier flame is wanted
• Micro Burner — a compact burner for small, close-range heating tasks

Browse the wider Chemistry Lab Equipment range for stands, clamps and glassware to complete the setup.

Frequently Asked Questions

Can this Bunsen burner be used with LPG cylinders?
Yes. It is suitable for both natural gas and LPG, so it can be used with piped supply or cylinder installations.

What does the needle valve do?
The threaded needle valve regulates how much gas reaches the tube, letting you set the flame size precisely without adjusting the gas tap on the bench.

How do I get a hot blue flame instead of a yellow one?
Rotate the air regulator to open the air holes. More air gives a hotter, non-luminous blue flame; less air gives the cooler yellow flame used as a visible safety flame.

Is the rubber gas tubing part of the supply?
The listing is for the burner. Tubing is available separately, such as our Rubber Pipe For Bunsen Burner; please mention it in your enquiry if needed.

Does the burner need any maintenance?
Occasionally remove soot and spilled residue from the tube top, keep the needle valve free of grit, and replace any tubing that has hardened or cracked.

What warranty is offered?
Warranty cover is set out in our quotation; contact us to confirm the terms for your order.

What details do you need to quote for a school or college?

Pipette Stand (Product Code: SLE/CH/17) is a polished beech wood rest that holds up to 12 pipettes lying horizontally, six on each side, so clean pipettes stay off the bench and their tips stay uncontaminated between readings. It is aimed at chemistry teachers, lab technicians and students who carry out repeated measurements with volumetric or graduated pipettes. The stand is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, and forms part of our chemistry lab equipment for schools and colleges in India and overseas.

Specifications

Typical Use

During volumetric analysis a pipette is picked up and put down many times — to rinse it, draw the aliquot, deliver it into the flask and repeat for concordant readings. Laying it flat on the bench risks rolling, breakage and a dirty tip. This stand gives each pipette a fixed horizontal place, and with six positions per side, two students or two groups can share one stand from opposite sides of a bench.

Horizontal storage also stops liquid left in the pipette from running into the bulb or the pipette filler. Label each position for a particular volume or reagent so pipettes are not mixed up between solutions, and wipe the polished wood dry if a drop is spilled on it.

Manufacturer

The stand is produced by Jain Scientific Equipments Private Limited, which operates under the ScienceLab name from Ambala, Haryana. The company is a registered MSME enterprise (Udyam UDYAM-HR-01-0003714), and its export consignments move under Importer-Exporter Code AAECJ8618A issued by the DGFT. Visit our company profile for background on the business.

• Bulb Type, Pipette Filler — a simple squeeze-bulb option for student use
• Pipette Stand, Vertical — an upright alternative where drainage is preferred

The full Chemistry Lab Equipment category lists more stands and racks for glassware.

Frequently Asked Questions

How many pipettes does the stand take?
Up to 12, arranged horizontally with 6 on each side.

Why store pipettes horizontally rather than upright?
Lying flat, a pipette cannot tip over and any remaining liquid does not run up into the filler. Upright stands are better when you want wet pipettes to drain, so some labs keep one of each.

What is it made of?
Well-polished beech wood, which is light, easy to wipe and gentle on glass.

Will it take my pipette sizes?
The supported diameter range is not stated in our listing for this model. Send us the pipette volumes you use via the contact page and we will confirm fit.

How should the wooden stand be cleaned?
Wipe with a damp cloth and dry straight away. Do not soak it in water or leave acids and alkalis on the surface.

Is there a warranty?
Warranty terms are given with the quotation — ask us for the terms applicable to your order.

Pipette Stand Foldable (Product Code: SLE/CH/18) is a wooden stand that holds up to 12 pipettes upright, accepting stems from 6 mm to 12 mm in diameter, and folds down when the session is over. Made from well-polished beech wood, it suits laboratories where bench and cupboard space is tight, such as shared school labs and mobile teaching setups. It is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, alongside our wider chemistry lab glassware and support range.

Specifications

Typical Use

Holding pipettes vertically lets rinse water and reagent traces drain downward after washing, so pipettes are ready for the next titration practical rather than left lying wet on a tray. Twelve places are enough for a group to keep separate pipettes for acid, base and standard solutions, each in its own marked slot, which cuts down on cross-contamination in volumetric work.

The folding design is the practical difference from a fixed stand. At the end of the period the stand can be emptied, folded and slid into a drawer or lab kit box, making it handy for labs that are set up and packed away daily or for teachers who carry apparatus between classrooms. Check that each pipette falls within the 6–12 mm range so it sits securely.

Frequently Asked Questions

Which pipette diameters fit this stand?
Pipettes from 6 mm to 12 mm in diameter. Stems thinner or thicker than that may not sit securely.

How many pipettes can it hold at once?
Up to 12, all standing vertically.

What is the advantage of the folding design?
It takes up far less room in storage, so the stand can be packed into a drawer or kit box between lessons and set up again in seconds.

Should pipettes go in tip down or tip up?
For draining after washing, most labs place them tip down; follow your own lab’s practice and keep tips clear of the bench surface.

How do I look after the beech wood?
Keep it dry, wipe off spills promptly, and avoid placing it near a burner or in a drying oven.

What warranty do you provide?
Terms are confirmed at quotation stage — please contact us for details.

Burette Rack (Product Code: SLE/CH/19) is a tiered storage frame in polished beech wood that keeps up to 13 burettes standing upright in vertical recesses along one side of its upper tier. It gives lab staff a single, orderly place to park a whole class set of burettes between titration sessions instead of laying them in drawers where stopcocks and tips get chipped. The rack is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, and belongs to our chemistry lab equipment for schools, colleges and quality-control labs in India and abroad.

Specifications

Typical Use

Burettes are long, fragile and easily damaged at the jet and stopcock. A rack like this is kept on a side bench or near the sink: after a titration class, students rinse their burettes and return them to the recesses, where they stand vertically and drain. At the start of the next volumetric analysis practical, the technician can see at a glance that all burettes are present and clean before handing them out to be mounted on a burette stand.

With capacity for 13, one rack covers a typical group practical. Because the recesses run along a single side, place the rack with that side facing the user so burettes can be lifted out without reaching across others. Keep the rack away from direct burner heat and wipe the polished wood if reagents drip onto it.

Manufacturer

This rack is manufactured by Jain Scientific Equipments Private Limited, known in the market as ScienceLab and based in Ambala, Haryana, India. Our company profile explains more about the company.

Test Tube Rack With Drying Pegs (Product Code: SLE/CH/21) combines two jobs on one polished beech wood platform: two rows of holes to hold test tubes during an experiment, and 12 vertical pegs on which freshly washed tubes can be hung upside down to dry quickly. Having both on a single base saves bench space and keeps clean and in-use tubes together at each workstation. Made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, it is a practical test tube rack for school labs in India, college practical rooms and teaching labs abroad.

Specifications

Typical Use

In qualitative chemistry practicals students often work through a sequence of test-tube reactions, washing and reusing the same tubes several times in one session. With this rack, tubes in use stand in the two rows of holes while washed tubes are inverted on the pegs to drain, so nobody has to walk to a separate drying board. It works just as well in biology for food tests or enzyme experiments that use multiple tubes side by side.

Rinse tubes with distilled water before hanging them so they dry without marks, and leave space between wet tubes on the pegs to let air circulate. Because the rack is wooden, it should be kept away from open flames; place hot tubes back only after they have cooled a little. For labs with special needs, such as a different hole layout, the design can be customised, which makes it a flexible piece of chemistry lab equipment for schools setting up new benches.

Test Tube Racks (Product Code: SLE/CH/20) are sturdy beech wood racks offered in two sizes — for 6 tubes or for 12 tubes — with a carefully polished finish that helps the wood resist damage from everyday spills. They give each student or group a stable place to stand test tubes during reactions, observations and waiting steps. The racks are made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, as part of our educational lab equipment for schools and colleges in India and international markets.

Specifications

Typical Use

Choosing between the two sizes is mostly about how the class is organised. The 6-tube rack suits an individual student doing a short sequence of tests, such as the preliminary tests in salt analysis or a set of indicator colour changes. The 12-tube rack suits a pair or small group running comparisons side by side — for example a reactivity series, a set of food tests or a dilution series where each tube needs to stay in order.

Many schools buy a mix: a 6-tube rack for each student position and a few 12-tube racks for demonstrations and group work. Keep the racks dry after washing up, stand hot tubes on a heat-resistant mat for a moment before returning them, and label positions with a marker strip when the order of tubes matters.

Manufacturer

These racks are manufactured by Jain Scientific Equipments Private Limited, trading as ScienceLab in Ambala, Haryana. For purchase departments and tender buyers who need vendor registration details, the company’s GSTIN is 06AAECJ8618A1ZT and its Legal Entity Identifier is 3358004HRD1JIVXKYX49.

Bottle Stand (Product Code: SLE/CH/22) is a polished beech wood holder with 45 mm diameter holes sized for 60 ml dropping bottles, supplied in a 6-hole or a 12-hole version. It keeps a bench set of indicators and test reagents upright, together and in a fixed order, so bottles are not knocked over or mixed up during practicals. The stand is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, for school chemistry lab equipment sets and college teaching labs.

Specifications

Typical Use

A bottle stand turns a loose collection of reagent bottles into an organised bench kit. Teachers typically fill a 6-hole stand with the essentials for acid-base indicator work — phenolphthalein, methyl orange, litmus and universal indicator — and a 12-hole stand with the wider range of test solutions used in salt analysis or food tests. Each group gets an identical stand, which makes it easy to check that every bottle has come back at the end of the lesson.

Keeping bottles in fixed positions also helps students find the right reagent quickly and reduces the chance of dropper mix-ups. Write the reagent name on the wood beside each hole or on a strip along the edge, wipe up drips so stains do not build up on the polish, and store the stand away from heat sources.

Manufacturer

The Bottle Stand is made by Jain Scientific Equipments Private Limited, a laboratory apparatus maker based in Ambala, Haryana, whose products are sold under the ScienceLab name. Read our company profile to learn more.

Related Chemistry Lab Equipment

Bottles and related items for filling the stand:

• Bottle Dropping — glass dropping bottles for indicators and test reagents
• Amber Dropping Bottle — for light-sensitive solutions such as silver nitrate
• Dropping Bottle — a plastic option for less breakable student sets
• Bottle Reagent, W.M. Glass — stock bottles for refilling the dropping bottles

Our Chemistry Lab Equipment category lists further stands and bench accessories.

Frequently Asked Questions

Which bottles fit the Bottle Stand?
It is designed for 60 ml dropping bottles; the holes are 45 mm in diameter. Before ordering other bottles, check that their outer diameter suits a 45 mm hole.

How many bottles does it hold?
Choose the 6-hole version for a compact indicator set or the 12-hole version for a fuller reagent kit.

Are dropping bottles included with the stand?
The listing is for the stand. Bottles are available separately — mention them in your enquiry if you want a complete set.

Can it be used for other small containers?

Burette Racks (Product Code: SLE/CH/23) is a single-burette holder built entirely from seasoned hardwood, with a 200 × 100 mm base, a rod of approximately 460 mm height and 16 mm diameter, and moulded plastic clamping screws that grip the burette without metal touching the glass. It gives each student a self-contained burette stand for titrations at the bench. Manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, it is a straightforward burette stand for labs in India and international markets that prefer wood over metal hardware.

Specifications

Typical Use

This holder is set up at a student position for acid-base, redox or precipitation titrations. The burette is clamped to the wooden rod with the plastic screws, the conical flask sits on the base beneath the jet (a white tile makes the end-point colour easier to see), and the student operates the stopcock with one hand while swirling the flask with the other. The hardwood base is broad enough to keep the tall rod steady during this routine.

Because it is dedicated to one burette and needs no boss head or separate clamp, it suits titration kit setups for schools where quick assembly matters. Tighten the plastic screws just enough to hold the burette vertical, check the alignment against a vertical edge before reading, and wipe the base if titrant drips onto it.

Manufacturer

Made by Jain Scientific Equipments Private Limited, which trades as ScienceLab and is based in Ambala, Haryana. You can read about the company in our company profile.

Balance Double Beam (Product Code: SLE/CH/24) is a single-pan mechanical balance on a wooden base with a capacity of 311 g and a sensitivity of ±2 mg. Captive weights slide along the beam scales and the result is read from an index scale and pointer, so there are no loose weights to lose or mix up. It is intended for speed when weighing routine samples, which makes it a dependable chemical balance for Indian school, college and training labs. The balance is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala.

Specifications

Typical Use

A beam balance of this kind is used wherever many samples of similar mass have to be weighed one after another: measuring out salts for solution preparation, weighing crucibles before and after heating in water-of-crystallisation experiments, or checking reagent portions in school practicals. Pharmacy and teaching labs that train students in the principle of the double beam balance also value it, because every step of the weighing is visible on the beams rather than hidden inside electronics.

Set the balance on a level, vibration-free bench away from draughts, zero it with the pan empty, and then slide the captive weights until the pointer returns to the index. Never place hot objects or loose chemicals directly on the 110 mm pan; use a watch glass or weighing boat, and clean the pan after each session.

Manufacturer

The balance is manufactured by Jain Scientific Equipments Private Limited, operating as ScienceLab from Ambala in Haryana, India. Details of the company are in our company profile.

Related Chemistry Lab Equipment

Other weighing options and alternatives from our range:

• Balance Triple Beam — higher capacity (610 g, extendable to 2610 g) for heavier samples
• Electronic Compact Balance — a digital option with LCD readout for quick weighing
• Double Beam Balance — the double beam model listed in our Balances range
• Triple-Beam Balance — a further mechanical alternative for class sets

More apparatus is available in the Chemistry Lab Equipment category.

Frequently Asked Questions

What is the maximum load of this balance?
311 g, with a sensitivity of ±2 mg.

Does it need a separate set of weights?
No separate weight box is listed as required — the balance uses captive weights that slide on the beam scales and stay attached to the instrument.

How large is the weighing pan?
The pan is 110 mm in diameter, with 170 mm from hook to pan.

Is a calibration certificate available?
Please discuss calibration documentation with us before ordering through the contact page; we will tell you what can be provided for your order.

Balance Triple Beam (Product Code: SLE/CH/25) is a single-pan mechanical balance with three notched weighing beams and centre-indicating sliding masses, giving a direct capacity of 610 g that can be raised to 2610 g by hanging supplementary masses on the end of the beam. Magnetic damping brings the pointer to rest quickly, and a 150 mm stainless steel pan takes beakers, specimens and bulky samples. Manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, it is a versatile piece of chemistry lab equipment for schools and colleges in India and abroad.

Specifications

Typical Use

The triple beam balance is a workhorse for class practicals that need a wider weighing range than a small beam balance offers. Students use it to find the mass of irregular solids for density determination, to weigh beakers of water in heat and calorimetry experiments, and to measure larger quantities of salts or soil samples. Mass measurement is part of CBSE physics practical work as much as chemistry, so one balance often serves both departments.

Weighing is done beam by beam: move the rider on the 0–500 g beam to the largest notch that keeps the pointer from dropping, then the rider on the 0–100 g beam, and finish with the fine 0–10 g beam read to 0.1 g. For loads over 610 g, hang the 1000 g supplementary masses on the beam end and add their value to the reading. Magnetic damping means the pointer settles in a few seconds, so students spend less time waiting. Store the masses in the base recess so they are not misplaced.

Manufacturer

This balance is produced by Jain Scientific Equipments Private Limited (CIN U29309HR2020PTC087597), which trades as ScienceLab. The company manufactures at its licensed factory at 449, HSIIDC Industrial Area, Saha, Ambala, Haryana (Factory Licence AMB-ONLINE-CHD-J-414). See our company profile for more.

• Triple Beam Balance — the triple beam model in our Measuring range
• Hanging Pan Balance — for weighing loads that need a hanging pan
• Force Meter/Spring Balance — for teaching the difference between mass and weight

Browse the complete Chemistry Lab Equipment category for more.

Frequently Asked Questions

What is the capacity of the Balance Triple Beam?
610 g using the three beams alone, and up to 2610 g when the two 1000 g supplementary masses are hung on the end of the beam.

What is the finest reading?
The finest beam reads 0 to 10 g in 0.1 g divisions.

Are the supplementary masses included?
Yes, the specification lists 2 × 1000 g supplementary masses, which store in the recessed base when not in use.

What does magnetic damping do?
It slows the beam’s swing so the pointer settles quickly, making readings faster and steadier than on an undamped balance.

Can you provide a calibration certificate?
Calibration paperwork should be discussed with us before ordering — please raise it through the contact page.

How should I care for the balance?
Keep it level and clean, return all riders to zero after use, and never drop objects onto the stainless steel pan.

What warranty applies?
Warranty terms are confirmed in the quotation for your order.

Do you supply balances for tenders and export?
Yes. Tender and distributor quantities can be supplied across India and to international markets; our company registration details are available on request.

Burner Bunsen With Stopcock (Product Code: SLE/CH/27) is a Bunsen burner fitted with its own stopcock, so the gas can be shut off completely at the burner rather than only at the bench tap. It also has an air regulator for flame control and comes with one spare gas nipple for use with LPG. That combination of on-burner shut-off and LPG readiness makes it a sensible choice for any school lab setup in India or abroad where many students light burners at once. It is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala.

Key Details

Typical Use

The stopcock is the reason to choose this burner. When a class is heating test tubes, running flame tests or boiling solutions, students can turn the gas off at the burner the moment they finish, without reaching across the bench to the service tap — and a teacher can see at a glance whether each burner is closed. It also lets a burner be left connected to the supply while turned fully off between steps of a practical.

For labs that run on cylinders, the spare nipple provided for LPG means the burner can be set up for that gas. Fit the correct nipple before connecting the tubing, then light the burner with the air regulator nearly closed and open it gradually to obtain the hot blue flame. Always close the stopcock and the bench tap at the end of the session.

Manufacturer

This burner comes from Jain Scientific Equipments Private Limited, an Ambala, Haryana manufacturer that sells its laboratory apparatus under the ScienceLab brand. Our company profile gives more background.

Related Chemistry Lab Equipment

Products that complete a burner station:

• Burner Tubing — connects the burner to the gas tap or cylinder regulator
• Bunsen Burner — a needle-valve model when fine flame adjustment matters more than shut-off
• Bunsen Burner Pilot Flame — an alternative with a pilot flame for repeated relighting
• Bunsen Burner with Stopcock — the stopcock burner listed in our Burners range

Find stands, gauze and glassware in the Chemistry Lab Equipment category.

Frequently Asked Questions

What is the stopcock for?
It stops the gas flow completely at the burner, giving students a shut-off within easy reach and an extra safety point besides the bench tap.

Can it be used with LPG?
Yes — a spare gas nipple is provided for use with LPG. For other gas supplies, tell us what your lab uses and we will confirm.

Can I control the flame temperature?
Yes, through the air regulator: more air gives a hotter blue flame, less air a cooler yellow flame.

What is the burner tube size and height?
Tube dimensions are not stated in our current listing for this model. Please contact us for the dimensional details.

How do I maintain the stopcock?
Operate it gently, keep it free of dust and spilled material, and check for gas leaks with soapy water if it ever feels loose. Replace tubing that shows cracks.

Is there a warranty?
Warranty terms are confirmed in our quotation for your order.

Can you equip a whole lab or an export order?
Yes. Send the number of burners, the gas type and the destination in India or abroad, and we will quote burners and tubing together.

Absorption Tower Calcium Chloride (Product Code: SLE/CH/28) is a cylindrical glass drying tower with a tubule at its base, 335 mm tall and 65 mm in diameter, holding 250 ml of drying agent. Filled with anhydrous calcium chloride or a similar desiccant, it removes moisture from a gas stream passing through it, or protects a reaction vessel from damp air. It is used in chemistry teaching labs, college practicals and research setups, and is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, within our chemistry lab glassware range.

Specifications

Typical Use

A drying tower sits in the gas line between the generator and the point of use. In a school or college gas collection apparatus, gas from a flask or Kipp-type generator enters through the tubule at the base, rises through the packed calcium chloride and leaves dry at the top, ready to be collected or passed into the next stage of the experiment. It can also be fitted to the inlet of an apparatus as a guard, so that air drawn in is dried first.

Place a plug of glass wool or cotton above the tubule so granules do not fall into the inlet, then fill with lumps or granules of drying agent, leaving space for another plug at the top. Clamp the tower upright on a stand, since a 335 mm glass column filled with desiccant is top-heavy. Replace the drying agent once it turns wet or cakes, and remember that calcium chloride is not suitable for drying every gas — check your procedure before use.

Manufacturer

The absorption tower is made by Jain Scientific Equipments Private Limited, which trades as ScienceLab from Ambala, Haryana, and supplies laboratory glassware and apparatus to educational and research buyers. More information is on our company profile.

Calcium Chloride Tube, Borosilicate Glass (Product Code: SLE/CH/29) is a U-shaped drying tube with a side tube and stopper, used to strip moisture from a gas stream or to keep damp air away from a reaction. Chemistry teachers, college demonstrators and analysts pack it with a granular drying agent and connect it in line with gas generators and reaction flasks. It belongs to the range of borosilicate laboratory glassware in India made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala.

Specifications

Typical Use

In a gas-preparation practical the tube sits between the generating flask and the receiver: gas enters one limb, passes through the packed drying agent and leaves through the side tube before it is collected. It is a routine addition to school gas collection apparatus in India whenever students need a dry sample of a gas such as hydrogen, oxygen or carbon dioxide. Fitted to the top of a reflux condenser, the same tube works as a guard tube that stops atmospheric moisture from entering a water-sensitive reaction.

Fill it with small lumps or granules rather than fine powder, which packs tightly and chokes the gas flow, and hold the charge in place with a loose plug of glass wool or cotton at each end. Replace the drying agent as soon as it turns wet or caked, and remember that calcium chloride is not suitable for drying ammonia.

Manufacturer

ScienceLab is the trading name of Jain Scientific Equipments Private Limited, based in Ambala, Haryana, which makes laboratory glassware, apparatus and teaching equipment for schools, colleges and research labs. The company is a registered MSME (Udyam UDYAM-HR-01-0003714) and ships overseas under Importer-Exporter Code AAECJ8618A issued by the DGFT. Read more on our company profile.

Carboy With Stop Cock (Product Code: SLE/CH/30) is a polypropylene storage container with a leak-proof spigot, used to hold and dispense distilled water and other laboratory solutions at the bench. Labs that want an alternative to heavy glass carboys choose it for daily water supply, rinsing stations and stock solutions. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, as part of its lab plastic ware range for schools, colleges and testing laboratories in India.

Specifications

Typical Use

Most labs place the carboy on a shelf or bench edge next to the water still so that students and technicians can draw distilled water from the spigot without lifting or tipping a heavy container. It is equally useful for bulk buffer, dilute acid or salt solutions that are drawn off in small portions through the day, which keeps the stock sealed and reduces contamination compared with repeated pouring.

Stand the carboy slightly above the receiving vessel so the tap drains freely, and keep the spigot closed when refilling. Label each carboy with its contents and filling date, rinse it with a little of the new solution before topping up, and use the autoclavable body to sterilise it when it is needed for microbiology or media work. This makes it a practical, durable piece of chemistry lab equipment in India for both teaching and routine testing.

Frequently Asked Questions

Which capacities are available?
Two: 10 litres and 20 litres. The smaller size is easier to lift for refilling; the larger one suits busy labs that use a lot of distilled water.

Can the carboy be autoclaved?
Yes, the polypropylene carboy is autoclavable. Loosen the closure before the cycle so pressure can equalise, and let it cool before handling.

Is the stop cock fixed or replaceable?
The leak-proof spigot is screwed to the body. For a spare spigot, please ask through our contact page with the capacity of your carboy.

Can I store organic solvents in it?
It is intended for distilled water and laboratory solutions. For organic solvents, strong oxidisers or other aggressive chemicals, confirm compatibility with us before use.

Why choose polypropylene instead of a glass carboy?
It is lighter to move and much less likely to break if knocked, which matters in student labs, and it can still be sterilised in an autoclave.

What should an institutional enquiry include?
The capacity, quantity, delivery address and any tender or purchase-order format you use. We supply buyers across India and international markets.

Beakers Euro Design (Product Code: SLE/CH/31) are polypropylene beakers offered in seven capacities, from a small 25 ml size for reagent portions up to 2000 ml for preparing bulk solutions. Being plastic, they are a shatter-resistant choice for student benches, weighing rooms and field kits where glass breakage is a concern. They are made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, and are a practical choice when a school in India wants a matching beaker set for every workstation.

Specifications

Typical Use

In class practicals these beakers hold water baths for test tubes at room temperature, carry measured portions of dilute acids and bases to the bench, collect filtrate under a funnel and serve as mixing vessels for indicator and salt solutions. The larger 1000 ml and 2000 ml sizes are handy for making up stock solutions or soaking small apparatus, while the 25 ml and 50 ml beakers suit weighing out solids on a balance.

Because polypropylene softens under direct heat, keep these beakers away from burner flames and hot plates and use borosilicate glass for anything that must be boiled. Wash them with warm water and a mild detergent using a soft brush, as abrasive powders scratch the surface. Their light weight and resistance to breakage make them a sensible part of school chemistry lab equipment in India for younger classes.

Manufacturer

The beakers come from Jain Scientific Equipments Private Limited, which operates under the ScienceLab name in Ambala, Haryana, and manufactures laboratory plasticware and teaching apparatus. You can learn more about us on the company profile page.

Glass Spirit Lamp (Product Code: SLE/CH/32) is a glass-bodied burner with a brass wick holder and a glass top cover, giving a small, steady flame from methylated spirit or alcohol. It is the go-to heat source for classrooms without a gas line, for flaming inoculating loops in biology, and for gentle warming of test tubes in junior science lab equipment sets. The lamp is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, alongside its wider range of chemistry lab glassware for schools in India and international markets.

Specifications

Typical Use

Students use the spirit lamp to warm small quantities of liquid in a test tube held with a holder, to dry a glass slide, or to sterilise a wire loop before and after transferring a culture. Because it needs no gas supply or tubing, it is easy to set out on every bench for a practical and to pack away afterwards; the 60 ml lamp suits short class sessions, while the 125 ml size runs longer between refills.

Fill the lamp away from any flame and do not overfill it. Keep the wick trimmed level so the flame burns evenly without smoking, and put the flame out by placing the glass top cover over it rather than blowing on it. The cover also stops the spirit from evaporating between lessons. Never refill a lamp that is still lit or warm.

Manufacturer

ScienceLab is the brand name used by Jain Scientific Equipments Private Limited of Ambala, Haryana, a maker of laboratory glassware, heating apparatus and school science equipment. Visit the company profile for more about the business.

Related Chemistry Lab Equipment

Accessories and alternatives that go with a spirit lamp:

• Wicks For Glass Spirit Burner — replacement wicks when the old one chars or shortens.
• Methylated Spirit — the usual fuel for the lamp.
• Test Tube Holder — holds the tube safely over the flame.
• Bunsen Burner — a hotter gas-fired option where a gas supply is available.

Other heating and support items are in Chemistry Lab Equipment.

Frequently Asked Questions

What fuel does the spirit lamp use?
Methylated spirit or a similar alcohol. Do not use petrol, kerosene or other volatile fuels in a glass spirit lamp.

What is the difference between the two sizes?
Only the fuel capacity: 60 ml or 125 ml. The larger lamp burns for longer before it needs refilling.

Is a wick included, and can it be replaced?
The lamp is built around its brass wick holder; please confirm the wick supplied with your order via our contact page. Replacement wicks are listed separately.

Is a spirit lamp hot enough for every experiment?
It gives a gentler flame than a Bunsen burner, which suits warming, drying and loop sterilisation. For strong heating or boiling larger volumes, use a gas burner.

How do I put out the flame safely?
Place the glass top cover over the wick to starve the flame of air, then leave the lamp to cool before moving or refilling it.

Can you supply lamps for a whole school or district order?
Yes. Send the size, quantity and delivery location; we supply institutions in India and international markets.

Aspirator Bottles Borosilicate (Product Code: SLE/CH/33) are glass bottles with a stopcock at the bottom and a stopper in the neck, built for storing a liquid and drawing it off from below without lifting the bottle. Laboratories use them for distilled water and working solutions, and chemistry teachers use them as water aspirators in gas and air-flow experiments. The bottles are made in borosilicate glass by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, and belong to its range of borosilicate glassware for laboratories in India and international markets.

Specifications

Typical Use

As a storage vessel, the aspirator bottle stands on a shelf with its stopcock over the sink or bench, so a measured flow of distilled water or reagent can be run off while the neck stays stoppered against dust. In experiments it works on water displacement: as water runs out of the bottom outlet, air or gas is drawn in through tubing at the top, which lets students pull a sample of air through an absorption tube or measure the volume of gas produced in a reaction.

Choose the 1 litre bottle for bench-top demonstrations, the 2 litre for group practicals and the 5 litre for a central water or solution supply. Glass lets you see the level and the clarity of the contents, and borosilicate stands up better than soda glass to washing with hot water. Place larger filled bottles on a firm, low shelf, and turn the stopcock gently to avoid stressing the glass joint. Schools choosing a laboratory glassware supplier in India can pair these bottles with plastic aspirators for younger classes.

Manufacturer

Jain Scientific Equipments Private Limited, trading as ScienceLab, manufactures laboratory glassware and apparatus in Ambala, Haryana. For vendor registration, the company's GSTIN is 06AAECJ8618A1ZT and its Legal Entity Identifier (LEI) is 3358004HRD1JIVXKYX49. See the company profile for more.

Frequently Asked Questions

Which capacities are offered?
Three: 1 litre, 2 litres and 5 litres, all in borosilicate glass with a bottom stopcock and neck stopper.

Can the bottle be used as an aspirator for drawing air or gas?
Yes. Fill it with water, connect tubing at the neck and open the stopcock; the outflowing water draws air or gas into the bottle.

Can I heat the bottle or pour boiling liquid into it?
It is a storage and dispensing vessel, not a heating vessel. Borosilicate tolerates hot washing water, but avoid direct heating and sudden temperature changes on a filled bottle.

What if the stopcock or stopper is damaged?
Contact us through the contact page with the bottle size and we will advise on replacement parts.

How should the bottle be cleaned?
Rinse through the neck and let the water run out of the stopcock so the outlet is flushed as well; finish with distilled water and drain with the stopper removed.

Bottle Reagent, W.M. Glass (Product Code: SLE/CH/34) is a wide-mouth glass reagent bottle closed with a dustproof flat stopper of glass or polythene. The wide mouth makes it easy to scoop out crystals, powders and granules, so it is the standard container for solid reagents on the chemistry shelf. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, a laboratory glassware manufacturer supplying schools, colleges and testing labs.

Specifications

Typical Use

A row of these bottles typically holds the solid salts, metal pieces and powders students draw from during salt analysis and preparation practicals, with each bottle labelled on the front and the flat stopper keeping dust and moisture out between lessons. Small 60 ml and 125 ml bottles are practical for the reagent set on each bench, while the 500 ml and 1000 ml sizes serve as stock containers in the prep room.

Use a clean, dry spatula for each reagent so that samples are not cross-contaminated, and put the stopper back straight away. A glass stopper suits most dry solids; a polythene stopper is the better choice for substances that tend to make a glass stopper stick, such as alkalis. For substances affected by light, choose the amber version of this bottle instead.

Manufacturer

Operating as ScienceLab, Jain Scientific Equipments Private Limited produces glassware, plasticware and laboratory apparatus at Ambala in Haryana. The company profile explains who we are and what we make.

Bottle Reagent, W.M. Glass Amber Colour (Product Code: SLE/CH/35) is an amber soda glass bottle with a wide mouth and a dustproof flat stopper. The amber tint cuts down the light reaching the contents, which is why chemists keep light-sensitive salts, stains and prepared reagents in it. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, and comes in six sizes, from a compact 30 ml bottle to a 1000 ml stock bottle.

Specifications

Typical Use

Amber bottles protect reagents that darken or decompose in daylight. In a school or college prep room they are the usual home for silver nitrate crystals, iodine and potassium permanganate, and for making up silver nitrate solution or iodine solution for the lab when the wide mouth is useful for adding solids. The 30 ml size is convenient for small, costly reagents shared across a class; the larger bottles hold the stock.

Store the bottles in a cupboard or on a shaded shelf even though the glass filters light, and label each one clearly, because amber glass makes it harder to see the contents. Close the flat stopper right after use to keep out dust and moisture, and wipe the neck before closing so that crystals do not build up around the stopper.

Manufacturer

This bottle is produced by Jain Scientific Equipments Private Limited, the Ambala, Haryana company behind the ScienceLab brand, which makes glassware and apparatus for education and testing. More information is on our company profile.

Bottle McCARTNEY, BIJOU (Product Code: SLE/CH/36) is a small narrow-mouth bottle for culture media and vaccines, sealed with an aluminium screw cap and a rubber liner. Microbiology, pathology and teaching labs use it to hold agar slopes, broths, sera and small reagent volumes in a closed, labelled container. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, and is a practical culture media bottle for laboratories in India, offered in three sizes.

Specifications

Typical Use

The name joins two long-established laboratory bottle styles: the small Bijou and the larger McCartney. In a microbiology lab, molten agar is dispensed into the bottles, which are then laid at an angle to set as slopes for maintaining stock cultures; the screw cap limits drying out during storage far better than a cotton plug. The smallest 7 ml bottle suits single-use aliquots of media or serum, the 14 ml size holds a working slope, and the 28 ml bottle takes larger broth or diluent volumes.

Label every bottle with its contents and date before filling, and keep the rubber liner seated inside the cap so the seal stays effective. When preparing media, fill the bottles through a funnel or dispenser to keep the neck clean, and tighten the caps fully only once the contents have cooled. Handled this way, the bottles are a dependable part of the microbiology lab equipment used in Indian colleges and diagnostic labs.

Aspirator Polythene (Product Code: SLE/CH/37) is a rigid, jerry can type polythene container with a plastic screw cap and a stopcock outlet, used to store water or solutions and run them off at the bench. It gives prep rooms, field stations and student labs a lightweight dispenser that will not shatter if it is knocked over. The aspirator is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, a chemistry lab instruments supplier to schools and colleges.

Key Details

Typical Use

The jerry can shape stacks neatly on a shelf and is easy to carry by hand, so the aspirator is often filled at a central water still and moved to wherever students are working. Placed at the edge of a bench, it lets them run off distilled water, dilute acids, buffers or washing solutions through the stopcock in controlled amounts. It is also handy on outdoor or field practicals where a glass bottle would be at risk of breaking. As a school laboratory equipment supplier in India, ScienceLab recommends it for junior classes, where durability matters most.

Keep the screw cap slightly open, or remove it, while dispensing so air can enter and the flow stays smooth. Rinse the container with some of the new solution before refilling, label the contents on the side, and flush the stopcock with clean water when changing from one solution to another.

Manufacturer

ScienceLab is the trading name of Jain Scientific Equipments Private Limited (CIN U29309HR2020PTC087597), headquartered in Ambala, Haryana. The company manufactures at its licensed factory at 449, HSIIDC Industrial Area, Saha, Ambala (Factory Licence AMB-ONLINE-CHD-J-414). See our company profile for details.

Bottle Dropping (Product Code: SLE/CH/38) is an amber glass bottle fitted with a rubber teat dropping pipette that is ground into the neck, so the pipette doubles as the stopper. It lets students add indicators and test reagents drop by drop without a separate dropper, and the amber glass helps protect light-sensitive solutions. The bottle is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, and is a staple of any acid base indicator kit on the school bench.

Specifications

Typical Use

Dropping bottles hold the indicators and small-volume reagents used in titrations, qualitative tests and pH work: phenolphthalein, methyl orange, universal indicator solution, dilute silver nitrate or barium chloride for anion tests, and similar solutions. A set of labelled bottles in a rack on each bench saves time and cuts waste, because students add exactly the few drops they need instead of pouring from a stock bottle. The 30 ml size is enough for a single bench; the 60 ml size is better for a shared tray.

Squeeze the teat before dipping the pipette into the liquid, never after, so no air is blown through the solution. Return the pipette to its own bottle straight away to avoid mixing reagents, keep the ground neck clean so the fit stays snug, and replace the rubber teat when it hardens or cracks.

Manufacturer

Jain Scientific Equipments Private Limited, known to customers as ScienceLab, is based in Ambala, Haryana and produces glassware and teaching apparatus for chemistry, biology and physics labs. Our company profile has more information.

• Dropping Bottle — the plastic alternative in our plasticware range.
• Test Tube Racks — hold the tubes that receive the drops during tests.

More bench items are in Chemistry Lab Equipment.

Frequently Asked Questions

What sizes are available?
Two capacities, 30 ml and 60 ml, both in amber glass with a ground-in rubber teat pipette.

Can I buy the dropper on its own?
The listing also includes a dropper-only option. Tell us the bottle size it must fit when you enquire so we can confirm the right pipette.

Does the amber glass make it suitable for light-sensitive solutions?
Amber glass reduces the light reaching the contents, which helps solutions such as silver nitrate keep longer. Store the bottles away from direct sunlight as well.

Can the rubber teat be replaced?
Rubber ages with use and some chemicals. Ask us about replacement teats or droppers through the contact page.

Is it suitable for strong acids or organic solvents?
Glass handles most reagents, but concentrated acids and many solvents attack rubber teats. Use it mainly for aqueous indicators and dilute reagents.

Can you supply complete sets for a school lab or distributor?
Yes. We supply institutions and distributors in India and international markets; give us the sizes, quantities and delivery location.

Stopcock (Product Code: SLE/CH/39) is an in-line polypropylene valve fitted with a PTFE plug, with serrated tubulations that accept tubing from 6 mm to 10 mm. Pushed into a length of rubber or silicone tubing, it turns a flexible line into one you can open, close or divert by hand. It is available as a 2-way or 3-way stopcock and is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, as one of the small lab equipment accessories that teaching and research labs in India keep in their spares drawer.

Specifications

Typical Use

A 2-way stopcock simply opens or shuts a line, for example on the outlet tubing of an aspirator bottle, on a water supply to a condenser, or on the vacuum line between a filter pump and a filter flask so suction can be released without pulling the tubing off. A 3-way stopcock connects one inlet to either of two outlets, which lets a technician switch gas between two pieces of apparatus, vent a system to air, or change over between two water feeds without disconnecting anything.

The serrations grip the tubing firmly; warming or wetting the tubing end makes it easier to push on. Turn the handle through its positions before connecting so you know which way each port is open. The PTFE plug turns smoothly without grease, which keeps the flow path clean, and the polypropylene body is light enough not to drag tubing down. Keeping a few in stock alongside other lab equipment spare parts saves re-plumbing a set-up when a line needs a new control point.

Manufacturer

Jain Scientific Equipments Private Limited trades as ScienceLab and makes laboratory plasticware, glassware and apparatus in Ambala, Haryana. Learn more on our company profile.

Tubing and apparatus a stopcock is typically fitted to:

• Silicone Tube — flexible tubing to push onto the serrated ends.
• Rubber Tubing — general-purpose tubing for water and gas lines.
• Filter Pump, Borosilicate Glass — vacuum source whose line can be isolated with the stopcock.
• Aspirator Polythene — a dispenser whose outlet tubing can be given extra flow control.

See more fittings and glassware in Chemistry Lab Equipment.

Frequently Asked Questions

What tubing sizes does it fit?
The serrated tubulations accept tubing from 6 mm to 10 mm. If your tubing is at either end of that range, send us its size through the contact page and we will confirm the fit.

Should I choose the 2-way or 3-way version?
Choose 2-way to open and close a single line; choose 3-way when one supply must be switched between two destinations or vented.

Does the PTFE plug need grease?
PTFE is naturally low-friction, so the plug turns without grease; this avoids contaminating the liquid or gas passing through.

Can it be used on a vacuum line?
Yes, it is commonly placed in vacuum tubing to isolate or release suction. Use thick-walled tubing so the line does not collapse.

How do I clean it?
Flush it with warm water in each open position, rinse with distilled water and let it dry; remove any deposits before they harden in the bore.

Can I order mixed 2-way and 3-way stopcocks in bulk?
Yes. List the quantity of each type in your enquiry; we supply labs in India and international markets.

Basin Crystallising Without Spout (Product Code: SLE/CH/40) is a flat-bottomed borosilicate glass dish used to evaporate saturated solutions slowly so that crystals can form in school and college chemistry laboratories. Its plain rim without a spout lets a clock glass or paper cover sit evenly, and it comes in three sizes from 100 x 50 mm to 190 x 100 mm. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer of borosilicate glassware in India, at its own factory in Ambala.

Specifications

What Is a Crystallising Basin Used For?

The classic class practical is growing copper sulphate crystals or alum crystals: a hot, filtered, saturated solution is poured into the basin, covered loosely and left undisturbed so that well-formed crystals grow over the following days. The wide, shallow shape gives a large surface for evaporation, and the flat bottom keeps the dish stable on a shelf or window sill. Beyond crystallisation, the basin serves as a shallow bath for cooling a flask, a tray for soaking slides or small glassware, and a container for demonstrations with floating or reacting solids.

When warming a solution in the basin, set it on a wire gauze rather than in a direct flame and heat gently. Clean off crystal crusts with warm water before they harden, since scraping can scratch the glass. A few basins in each size round out a crystallization kit for school practicals, from individual student work to teacher demonstrations.

What to Specify When Ordering

• Size, given as diameter x depth: 100 x 50 mm, 150 x 75 mm or 190 x 100 mm
• Quantity of each size, for example the smallest for individual students and the largest for demonstrations or bigger batches
• Matching accessories, such as clock glasses to cover the basins or stirring rods for preparing the solution
• Delivery location, so the manufacturer can quote packing and dispatch for India or international markets

OEM Manufacturer

Basin Crystallising Without Spout is manufactured by Jain Scientific Equipments Private Limited, which trades as ScienceLab and is the OEM (original equipment manufacturer) of this borosilicate basin. The company makes its laboratory glassware and chemistry teaching apparatus at its own licensed factory at 449, HSIIDC Industrial Area, Saha, Ambala, Haryana, India, and supplies it factory-direct to schools, colleges, institutions, dealers and importers in India and international markets. Because quotations come straight from the manufacturer, ask us about repeat orders, extra sizes or replacement basins. Read more on the company profile.

Items used in the same crystallisation workflow:

• Clock Glass (Borosilicate Glass) — a cover that keeps dust out while evaporation continues
• Filter Paper — clears the hot solution of insoluble matter before it goes into the basin
• Stirring Rod, Glass — dissolves the solid and helps seed crystals
• Gauze Wire, Ceramic Centre — spreads the heat when the basin is warmed
• Potash Alum — a salt that grows well-shaped crystals from a saturated solution

More glassware is listed in Chemistry Lab Equipment.

Frequently Asked Questions

What sizes does the Basin Crystallising Without Spout come in?
The Basin Crystallising Without Spout comes in three sizes, given as diameter x depth: 100 x 50 mm, 150 x 75 mm and 190 x 100 mm. State the size and quantity of each when you ask for a quotation.

Why choose a crystallising basin without a spout?
A crystallising basin without a spout has a plain, level rim, so a clock glass or filter-paper cover sits flat and there is no low point where solution can creep over the edge during slow evaporation. If you mainly need to pour, a spouted design suits better.

Can the Basin Crystallising Without Spout be heated?
Yes, gently. The Basin Crystallising Without Spout is borosilicate glass, so it handles hot solutions and gentle warming on a wire gauze well; avoid a direct flame on an empty or dry basin and avoid sudden cooling.

How do I get large, well-shaped crystals in the basin?
Use a hot, filtered, saturated solution, cover the crystallising basin loosely and leave it somewhere still at a steady temperature. Moving the Basin Crystallising Without Spout while crystals grow disturbs them and produces many small crystals instead of a few large ones.

Who manufactures the Basin Crystallising Without Spout?
The Basin Crystallising Without Spout is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), the OEM, at its own licensed factory at Saha, Ambala, Haryana, India, and is sold factory-direct to schools, colleges, dealers and importers.

Can you supply crystallising basins for class sets or export orders?
Yes. ScienceLab supplies the Basin Crystallising Without Spout in class-set quantities to schools, colleges and distributors across India and international markets; tell us the sizes, quantities and destination so the manufacturer can quote directly.

Burette Stand and Funnel Stand (Product Code: SLE/CH/41) is a polished hardwood stand that holds one burette and one funnel at the same time, with cork-lined jaws, plastic screws and a base standing on four rubber feet. It gives each titration or filtration station a steady, all-in-one support without a separate retort stand and clamps. Made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, it is a practical burette stand for student benches in school and college labs across India.

Specifications

Typical Use

During an acid-base or redox titration, the burette is gripped in the cork-lined jaw above a conical flask while the funnel position holds a small funnel ready for refilling, or supports a filter funnel for a parallel filtration. Cork protects the glass from scratching and grips it without the need to overtighten, and the plastic screws do not rust from acid splashes the way metal ones can. This makes it a tidy fit for school titration kits, with one stand set out at each bench.

Align the burette vertically before tightening the jaw, and place a white tile or sheet of paper on the base under the flask so the end point colour change is easy to see. Wipe spills off the wood promptly with a damp cloth and dry it, and keep the stand away from standing water so the polish lasts.

Burette (Product Code: SLE/CH/42) is a plastic burette with a transparent acrylic body and a leakproof stopcock fitted with a self-lubricating PTFE plug, used to deliver measured volumes of titrant in volumetric analysis. Each burette is individually calibrated, and the plastic body is much less prone to breakage than glass, which suits student titrations. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, in 25 ml, 50 ml and 100 ml capacities.

Specifications

Typical Use

In a standard acid-base titration the burette is clamped vertically, filled with the titrant, and run into a conical flask containing the analyte and a few drops of indicator until the colour changes at the end point. The acrylic burette handles the dilute hydrochloric acid, sulphuric acid and sodium hydroxide solutions used in most school and college volumetric analysis kits in India, and its clear body lets students read the meniscus easily. The 25 ml size suits short titrations with small samples, 50 ml is the common class size, and 100 ml avoids refilling during longer runs.

Rinse the burette with a little of the titrant before filling, remove the air bubble from the tip by running some liquid through, and read the bottom of the meniscus at eye level. Keep it away from hydrofluoric acid, ammonium hydroxide and organic solvents, and do not dry it in a hot oven; rinse with distilled water and let it drain upside down instead.

Manufacturer

ScienceLab is the trade name of Jain Scientific Equipments Private Limited, a manufacturer of laboratory plasticware, glassware and apparatus located in Ambala, Haryana. Visit the company profile to learn more.

Fisher Clamp (Product Code: SLE/CH/43) is a burette clamp moulded in polypropylene, which makes it completely corrosion proof around acids, alkalis and wet benches. A spring-loaded jack in the middle holds the burette in a vice-like grip so it cannot slip, and two tapered wedges lock the clamp firmly onto a support rod. It comes as a single or double clamp and is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, for chemistry labs looking for a burette clamp in India that stands up to acid spills and damp benches.

Specifications

Typical Use

The clamp slides onto the vertical rod of a retort stand and is locked in place with its wedges; the burette is then pressed against the spring-loaded jack, which pushes it into the jaws and holds it upright over the titration flask. The single version holds one burette, while the double version holds two side by side, which is useful when a titration uses two solutions or when two students share one stand. Because the whole clamp is plastic, it does not rust or seize if acid or alkali drips onto it during a titration.

Set the clamp at a height that leaves room to swirl a conical flask under the burette tip, and check that the burette hangs vertically before starting. Wipe off any spills after each session. Paired with a sturdy retort stand, it gives a secure set-up for school and college titration practicals in labs across India.

Manufacturer

The Fisher Clamp is made by Jain Scientific Equipments Private Limited, which trades under the ScienceLab name from Ambala, Haryana, producing stands, clamps, plasticware and glassware for teaching laboratories. See our company profile for more.

Related Chemistry Lab Equipment

Supports and glassware used with a Fisher clamp:

• Retort Stand — provides the upright rod the clamp is fixed to.
• Burette — acrylic burette to hold in the clamp.
• Fisher Clamp (Routine Improved Model) — an alternative Fisher clamp model.
• Burette Clamp, Die Cast – Double Clamp — a metal double clamp option.

More clamps and stands are listed in Chemistry Lab Equipment.

Frequently Asked Questions

What is the difference between the single and double clamp?
The single clamp holds one burette; the double clamp holds two burettes on the same rod.

Which rod sizes does it fit?
The tapered wedges are designed to grip rods of 1/2 inch or 3/8 inch diameter. For other rod sizes, ask us via the contact page.

Will it hold both glass and plastic burettes?
Yes, the spring-loaded jack presses the burette into the jaws whichever material it is made of. For unusually thick or thin burettes, confirm the fit with us.

Why choose polypropylene over a metal clamp?
Polypropylene is completely corrosion proof, so it will not rust, stain or seize after acid or alkali spills, and it is lighter on the stand.

How should I clean it?
Rinse with water, wipe dry and keep it away from direct flames or hot plates, as polypropylene softens with heat.

Can you supply clamps in quantity for a school or distributor?
Yes. State how many single and double clamps you need; we supply buyers in India and international markets.

New Improved Organic And Inorganic Molecular Set (Product Code: SLE/CH/44) is a ball-and-link model set for building organic molecules together with inorganic structures, ranging from simple molecules to complex ions. It is a versatile demonstration and student set suited to ordinary and advanced level courses or equivalent, so chemistry teachers can show bonding at the front of the class and learners can then build the same structures themselves. The set is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, as part of its school chemistry lab equipment in India.

Specifications

The set comprises the following balls:

• Carbon (6)
• Oxygen (22)
• Nitrogen (10)
• Sulphur (12)
• Halogen (8)
• Metal (14)
• Phosphorus (7)
• Hydrogen (14)

Typical Use

Because the set carries two families of links, one model can show more than one kind of bonding. Students join atoms with the grey links to build single-bonded and double-bonded covalent molecules such as methane, ethene or ethanol, then switch to the mauve links to mark a hydrogen bond between two water molecules, the coordinate bond in an ammonium ion, or the ionic attraction in a simple salt. Seeing the bond types in different colours makes it easier to discuss why some substances are gases, why water has a high boiling point for its size, and how a metal ion holds its surrounding ligands in a complex ion.

As a chemistry teaching kit for schools in India, it works well when the teacher builds a reference model first and small groups then copy and modify it. Sorting the balls by atom type into a tray before the lesson, and counting them back afterwards, keeps the set complete from one class to the next. Store the flexible links loosely rather than tightly bent so they keep their shape.

Manufacturer

Jain Scientific Equipments Private Limited trades under the ScienceLab name and is based in Ambala, Haryana. The company produces teaching apparatus for chemistry, physics and biology laboratories and serves schools, colleges and training institutes in India and international markets. More about the business is available on the company profile.

Related Chemistry Lab Equipment

These items help build a complete structure-and-bonding module around this set:

• Molecular Model Set – Inorganic/Organic Student — a smaller set for individual or paired practice after the class demonstration.
• Molecular Model Set – Inorganic/Organic Teacher — a teacher set with lone-pair paddles for discussing molecular shape.
• Organic Chemistry Molecular Models Kits — an alternative for courses that concentrate on organic structures.
• Atom Activity Model — introduces the parts of the atom before students move on to bonding.

See the full range in our Chemistry Lab Equipment category.

Frequently Asked Questions

Which atoms are included in the set?
Balls for carbon, oxygen, nitrogen, sulphur, halogen, metal, phosphorus and hydrogen, in the quantities shown above, plus grey and mauve links. Please ask us to confirm the packing list in your quotation if exact counts matter for your lesson plan.

Can it show ionic and hydrogen bonds as well as covalent bonds?
Yes. Grey links in two lengths represent single and double covalent bonds, and separate mauve links represent ionic, coordinate and hydrogen bonds.

Is it meant for the teacher or for students?
Both. It is described as a demonstration student set, so it can be used at the front of the class or handed to a group for hands-on model building at ordinary and advanced level.

Can I order extra balls or links later?
Please ask through our contact page with the atom types and quantities you need, and we will tell you what can be supplied separately.

How should the set be cleaned?
Wipe balls and links with a damp cloth and mild soap, let them dry fully, and keep them in their box away from direct sun and heat so the links do not deform.

What should a school or college quotation request include?
The number of sets, the course level, whether you also need student or teacher sets for the same lab, and the delivery address. That lets us quote everything in one reply.

Do you supply schools outside India?
Yes, we supply institutions in India and international markets. Share your country and quantity so that packing and shipping can be confirmed with the quotation.

Brush Burette (Product Code: SLE/CH/45) is a long cleaning brush with a nylon bristle end mounted on an iron wire handle, 900 mm in overall length, so it can be passed down the full bore of a burette from the open top. Lab assistants, teachers and students use it to loosen residue and stubborn films from the inside of burettes before rinsing and refilling them for the next titration. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, which acts as a chemistry consumables supplier in India and for overseas laboratories.

Specifications

Typical Use

A burette that is not properly clean holds droplets on its inner wall, which spoils the meniscus reading and the accuracy of a titration. After a practical, drain the burette, fill it partly with warm water and a little laboratory detergent, and slide the brush in from the top. Work it gently up and down along the graduated section, then rinse several times with tap water and finally with distilled water. When water drains from the wall in an even film without forming beads, the burette is ready to be rinsed with titrant and used again.

The long wire handle lets you reach the lower end without forcing the brush, but stop short of the stopcock and jet so the wire tip does not scratch the bore or dislodge a plug. In busy school titration sessions it helps to keep one brush beside each sink, and to hang it bristle-end down after use so water drains away from the wire.

Brush Test Tube (Product Code: SLE/CH/46) is a hand brush for scrubbing test tubes, made with nylon bristles set on an iron wire stem. It measures 260 mm overall with a bristle head of 90 x 45 mm, a compact size that is easy to handle at a student sink. Schools, colleges and routine testing labs use it to remove precipitates, dried solutions and scorch marks after qualitative tests. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, a lab consumables supplier in India that also serves overseas institutions.

Specifications

Typical Use

Salt analysis, flame tests and simple reactions leave test tubes coated with precipitates, oily films or charred residue. Empty the tube into the correct waste container, add a little water and detergent, then twist the brush in and out so the nylon bristles sweep the rounded bottom as well as the walls. Rinse with tap water and finish with distilled water before standing the tube upside down to dry.

Push the brush in gently and do not ram it against the bottom of the tube, because the wire stem can crack thin glass. Stubborn deposits usually come away more easily after a short soak rather than hard scrubbing. For a class set, one brush per bench keeps the clean-up at the end of a practical quick and orderly.

Supplier

ScienceLab is the trading name of Jain Scientific Equipments Private Limited, based in Ambala, Haryana. Alongside the teaching apparatus it manufactures, the company supplies everyday consumables such as cleaning brushes so that institutions can source a complete laboratory order from one place.

Which test tubes does it suit?
Compare the head size with the inside diameter of your tubes. If you are unsure, send us your tube sizes through the contact page and we will advise.

Why nylon bristles?
Nylon is flexible and tolerates water and detergents well, so it can scrub glass repeatedly without the bristles going soft quickly.

Can I use it with acids or cleaning solutions?
Brief contact during rinsing is normally fine, but do not leave the brush standing in acid or harsh cleaning liquids, because the iron wire stem can corrode.

How many brushes should a school lab order?
Many labs keep one per student bench plus spares, as brushes wear out with regular use. Tell us your bench count and we can suggest a quantity for the quotation.

Rubber Cork (Product Code: SLE/CH/47) is a tapered stopper in soft, solid red rubber for closing test tubes, flasks and bottles and for carrying glass tubing into sealed apparatus. The rubber resists acid, alkali and ammonia, and the corks are offered with one hole or with two holes in a wide series of sizes. Chemistry teachers and lab technicians looking for a dependable rubber stopper for lab work in India use them to build gas generators, distillation set-ups and wash bottles. They are supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala.

Specifications

Available sizes (all dimensions in mm):

Typical Use

A one-hole cork holds a thermometer or a single delivery tube, for example when heating a solid in a boiling tube and leading the gas away to a trough. A two-hole cork lets you fit a thistle funnel and a delivery tube into a conical flask to make a simple gas generator, or build a wash bottle with a long and a short tube. The taper means one size seals a range of neck openings, so the cork should sit roughly one-third to one-half of its height inside the neck.

To choose a size, measure the inside diameter of the neck: it should fall between the bottom and top diameters listed above. Moisten glass tubing with water or glycerol and twist it gently through the hole while protecting your hand with a cloth; never force the glass. Rinse corks after use and keep them away from oils, solvents and direct sunlight, which can harden rubber over time.

Supplier

Jain Scientific Equipments Private Limited, trading as ScienceLab, is based in Ambala, Haryana. Besides the apparatus it manufactures, the company supplies consumables such as rubber corks so that schools, colleges and laboratories in India and international markets can complete their orders in one place.

Oak Ridge Centrifuge Tubes (Product Code: SLE/CH/49) are screw-cap centrifuge tubes made of polypropylene, offered in 30 ml and 50 ml capacities. Their excellent contact clarity lets you see a pellet or phase boundary through the wall, and they can be used up to 50000 x G, which makes them suitable for high-speed separations in chemistry, biochemistry and life-science labs. College and research labs pair them with a suitable laboratory centrifuge in India to spin down precipitates, cells and suspensions. They are supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala.

Specifications

Typical Use

These tubes are used wherever a sample needs to be separated into a solid pellet and a clear supernatant: collecting a fine precipitate in analytical chemistry, pelleting bacteria or yeast from a culture, clarifying a cell lysate, or separating two liquid phases after an extraction. The clear polypropylene wall helps you judge when the supernatant can be decanted without disturbing the pellet.

Fill tubes to similar levels and place them opposite each other so the rotor stays balanced. The 50000 x G figure is the tube's own limit; the force actually applied depends on your centrifuge's rotor radius and speed, so always stay within the lower of the tube rating and the rotor rating. Because the screw cap should not be used below 4°C, check the temperature setting before a refrigerated run, and inspect tubes for cracks or crazing before each reuse.

Supplier

These tubes are supplied by ScienceLab, the trading name of Jain Scientific Equipments Private Limited, Ambala, Haryana. For vendor registration, buyers can use the supplying company's CIN U29309HR2020PTC087597 and GSTIN 06AAECJ8618A1ZT. The company serves laboratories in India and international markets; more is on the company profile.

Explore the wider Chemistry Lab Equipment category.

Frequently Asked Questions

What capacities are available?
Two: 30 ml and 50 ml. State the capacity and quantity for each in your enquiry.

How fast can these tubes be spun?
They can be used up to 50000 x G. The real limit in your lab is whichever is lower: that figure or the rating of the rotor you are using.

Can I use them in a refrigerated centrifuge?
Yes, as long as the run stays at or above 4°C, because the screw cap should not be used below 4°C.

Will they fit my centrifuge?
That depends on your rotor or bucket inserts. Send us the centrifuge make and rotor details through our contact page and we will help check compatibility.

Can the tubes be autoclaved or reused?

Deflagrating Spoon (Product Code: SLE/CH/50) is a long-handled combustion spoon for burning small quantities of a substance inside a jar of gas. It has a brass cup of about 20 mm diameter on a chrome-plated iron wire of about 350 mm, and comes complete with a 75 mm sliding disc and a cork that hold the wire at any length. Chemistry teachers use it for classic demonstrations of combustion in oxygen, and students use it in supervised practicals on the properties of gases. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala.

Specifications

Typical Use

A typical lesson starts by collecting jars of oxygen over water. A small piece of sulphur or charcoal is placed in the brass cup, warmed in a Bunsen flame until it starts to burn, and then lowered into the jar so the class can compare how brightly it burns in air and in pure oxygen. The sliding disc rests across the mouth of the jar like a lid, slowing the escape of gas and fumes, while the cork fixes the wire so the cup hangs at the chosen depth. Afterwards a little water or indicator can be shaken in the jar to test whether the product is an acidic or basic oxide.

Use only small amounts, and carry out sulphur burning in a fume cupboard or a well-ventilated room, because the gas produced is irritating. Let the spoon cool before scraping out residue, and clean the cup after each use so deposits do not build up. This spoon forms part of any basic set of gas collection apparatus in India, alongside gas jars, a trough and a beehive shelf.

Manufacturer

ScienceLab is the trading name of Jain Scientific Equipments Private Limited, which makes chemistry, physics and biology teaching apparatus in Ambala, Haryana, for schools and colleges in India and international markets. Learn more on the company profile.

• Pneumatic Trough — the water trough used for collecting gas over water.
• Bunsen Burner — to ignite the sample in the cup before it goes into the jar.

For more apparatus, visit our Chemistry Lab Equipment category.

Frequently Asked Questions

What is the sliding disc for?
The 75 mm disc sits over the mouth of the gas jar like a lid, limiting the loss of gas and fumes while the substance burns. Together with the cork it lets you set the wire at any length.

How large is the cup?
The brass cup is about 20 mm in diameter, which is enough for the small quantities used in school demonstrations.

Which substances are usually burned in it?
Common choices are sulphur, charcoal and similar small solids for oxygen demonstrations. Always follow your school's safety guidance on which substances and amounts are permitted.

Will the disc fit my gas jars?
It fits jars whose mouth is smaller than 75 mm across. If you are unsure, give us your jar size through the contact page.

With a boss head and clamp, the stand holds a burette for titration, a flask over a burner, or a condenser during distillation; with a retort ring and wire gauze it becomes a heating support or a funnel holder for filtration. The shorter rods suit single-clamp jobs at a student bench, while the longer rods and larger bases are better for tall assemblies such as a distillation set-up where the flask, still head and condenser are clamped at different heights.

For stability, arrange the apparatus so its weight sits over the base rather than beyond it, and turn the base so the long side lies under the load. Check that the nut under the base is tight before loading the rod, and wipe spills off the painted base promptly. A class set of stands with matching clamps and bosses, the standard lab stand, clamp and boss head arrangement found across India, makes practical sessions quicker to set up.

Test Tube Stand 3 Tier (Product Code: SLE/CH/52) is a moulded polypropylene rack built in three tiers: tubes pass through the upper and middle plates and rest on the base, so they stand straight while their contents stay in view. The layout makes tubes easy to insert and remove, and the rack is autoclavable and can withstand sub-freezing temperatures, so it moves from the bench to the sterilizer or the freezer without a change of rack. It suits chemistry, microbiology and clinical labs in schools, colleges and hospitals, and is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, within its lab plastic ware range for India and overseas buyers.

Specifications

Typical Use

Because each tube is guided at two heights, it stays upright even when only a few places are filled, which is useful for colour-change tests, serial dilutions and precipitation reactions where students need to compare tubes side by side. In microbiology, a rack of culture tubes can go through the autoclave and then be stored cold without transferring the tubes. For sample storage, the rack's tolerance of sub-freezing temperatures means it can hold labelled tubes in a freezer.

Choose the coloured PP rack when you want to colour-code sets, for example one colour per class group or per test series. Wash the rack in warm detergent solution, rinse, and let it dry before autoclaving. Load tubes of a diameter that passes freely through the upper plate; forcing larger tubes can strain the plates.

Test Tube Stand (Wire Pattern) (Product Code: SLE/CH/53) is a grid-style test tube rack that follows the open layout of a traditional wire rack but is moulded from a special blend of polypropylene. The blend makes the rack sink in a water bath and stay stable even in agitated water, so it is an economical substitute for wire racks in incubation and heating work. It is submersible, autoclavable, stackable when empty and easy to take apart for cleaning, and is offered in formats from 13 mm x 90 tubes to 30 mm x 21 tubes. The rack is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala.

Specifications

Formats (tube diameter x number of tubes):

• 13 mm x 90 tubes
• 16 mm x 60 tubes
• 20 mm x 40 tubes
• 25 mm x 24 tubes
• 30 mm x 21 tubes

Typical Use

Ordinary plastic racks tend to float and tip when placed in a water bath, spilling tubes. This rack is weighted by its material rather than by metal, so a full load of tubes can be incubated at a set temperature for enzyme experiments, serological tests, sugar tests with Benedict's reagent or culture work, and the rack stays put even if the bath is shaken. The open grid lets water circulate around every tube for even heating, and the rack can go straight from the bath into the autoclave.

Pick the format by tube diameter: the 13 mm and 16 mm versions suit small test tubes and culture tubes in large numbers, while the 25 mm and 30 mm versions take boiling tubes and larger vessels. Different colours help separate batches or classes, and when the session is over the racks stack together to save cupboard space. This makes it a practical piece of microbiology lab equipment in India for teaching and routine labs alike.

Test Tube Stand, Polythene (Product Code: SLE/CH/54) is a compact student rack in high-density polythene that holds 2 tubes of 25 mm diameter and 4 tubes of 16 mm diameter, with 6 vertical pegs along the rear edge of the base for drying washed tubes. Its 210 x 82 mm base gives the rack a steady footprint on a crowded bench. It is a natural choice for individual student places in school and college chemistry and biology labs, and is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, a school laboratory equipment supplier in India and abroad.

Specifications

Typical Use

The mixed layout matches the way many school practicals are run: the four smaller places hold the test tubes for a set of reagent tests, while the two larger places take boiling tubes or wider tubes for heating, gas tests or larger volumes. A single rack therefore covers a typical student's needs for a qualitative analysis session, and the drying pegs mean washed tubes can be left upside down on the same rack at the end of the lesson.

High-density polythene does not rust and is easy to wipe clean after spills of dilute acids or salt solutions. Keep hot tubes in a holder or on a heatproof mat until they have cooled, rather than placing them straight into the plastic rack. With one rack per student, benches stay tidier and breakages from rolling tubes are reduced.

Drying Rack (Product Code: SLE/CH/55) is a peg board in ABS plastic with 18 pegs on which washed flasks, beakers and test tubes are hung upside down to drain and air-dry. Two holes are provided so the rack can be fixed to the wall above a sink, keeping wet glassware off the bench and letting water run straight away. School labs, college practical rooms and routine testing labs use it at their wash-up stations. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, as part of its chemistry lab equipment in India and for overseas buyers.

Specifications

Typical Use

After a practical, glassware is scrubbed, rinsed with tap water and given a final rinse with distilled water. Hanging each item neck-down on a peg lets the last of the water drain out and air circulate inside, so borosilicate laboratory glassware is dry and free of drip marks by the next lesson. Heavier items such as conical flasks are best placed on the lower pegs and light test tubes higher up, so that drips do not fall onto glass that is already dry.

Mount the rack on a wall above the sink or draining board, using screws suited to your wall through the two holes, and check that it is level. ABS is easy to wipe down, so clean the pegs occasionally to stop residue transferring to freshly washed glass. Do not hang glassware that is still hot from an oven or flame on the plastic pegs.

Float Rack (Product Code: SLE/CH/56) is a compact polypropylene rack that holds 16 microcentrifuge tubes of 1.5 ml on the surface of a water bath during incubation. Its top carries a raised alphanumeric index so each position can be identified at a glance, and a central rod lets you lift the loaded rack out of the water without touching the tubes. Easy to load and autoclavable, it is used in microbiology and immunology labs for enzyme digestions, heat treatments and other timed incubations of small samples. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala.

Specifications

Typical Use

Many molecular biology and immunology protocols call for a short incubation of microtubes at a fixed temperature, such as a restriction digest, a heat-inactivation step, antigen–antibody binding or a heat-shock transformation. Pressing the capped tubes into the float rack and setting it on the bath keeps them upright, in contact with the water and in a known order, so no tube tips over or gets mixed up. The raised index lets you note positions on your worksheet and find the right tube again after incubation.

Close tube caps firmly before floating the rack so no water enters. Lift the rack by its central rod, shake off excess water, and move it to a bench rack or centrifuge. Between uses, wash the rack and autoclave it if your protocol requires sterile handling. It fits easily into a small bath, making it a convenient part of a microbiology lab setup in India for teaching or research.

Beehive Shelf, Porcelain (Product Code: SLE/CH/57) is a small dome-shaped porcelain support placed in a pneumatic trough for collecting gases over water. It is glazed inside and outside, so it sheds water and deposits easily, and it is offered in 75 mm and 100 mm diameters to suit different trough and gas jar sizes. Chemistry teachers and students use it whenever oxygen, hydrogen or another sparingly soluble gas is prepared and collected in the lab. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, a school science lab equipment manufacturer serving India and international markets.

Specifications

Typical Use

A beehive shelf lifts the mouth of a gas jar just clear of the bottom of the trough. The delivery tube from the gas generator is led under the shelf, and the gas rises through the opening in the top into an inverted gas jar that was filled with water and stood on the shelf. As gas collects, it pushes the water out of the jar; once the jar is full, a cover is slid under its mouth and it is lifted out ready for testing. This set-up is used for classic experiments such as collecting oxygen from heated potassium permanganate or hydrogen from zinc and dilute acid.

The 75 mm size suits smaller troughs and narrow gas jars, while the 100 mm size gives a broader platform for wider jars. Because the porcelain is glazed on both faces it does not soak up water, and it can simply be rinsed and dried after the lesson. Handle it with care, as porcelain can chip if dropped into a trough or knocked against glassware.

Funnel Holder (Product Code: SLE/CH/58) is a non-corrosive holder that keeps a funnel steady above a flask or beaker during filtration. Its outer ring takes funnels of 3 to 6 inch diameter, and a removable inner lid holds smaller funnels of 1 to 3 inch diameter, so one holder covers everything from a small analytical funnel to a large filling funnel. It is available as a Single Funnel Holder or a Double Funnel Holder for running two filtrations side by side. The holder is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, a laboratory equipment supplier in India and to overseas institutions.

Specifications

Typical Use

Gravity filtration is one of the first separation techniques students learn: a folded filter paper is placed in a funnel, the funnel is held above a conical flask or beaker, and the mixture is poured in so the solid stays on the paper and the clear filtrate collects below. Holding the funnel by hand is tiring and risks spills, so a holder frees both hands for pouring and rinsing. With the inner lid in place, small funnels sit securely for filtering a few millilitres in salt analysis; lift the lid out and the outer ring takes a larger funnel for filtering a whole reaction mixture or decanting a solution.

The double version is handy when comparing two filtrations, such as filtering the same mixture through different papers, or when two students share one bench position. Position the stem of the funnel so it touches the inside wall of the receiving vessel; this speeds filtration and prevents splashing. Because the holder is non-corrosive, it can simply be rinsed after contact with dilute acids or salt solutions and left to dry.

Manufacturer

ScienceLab is the trading name used by Jain Scientific Equipments Private Limited, an apparatus maker in Ambala, Haryana, that supplies schools, colleges and laboratories in India and international markets. Visit the company profile to learn more.

• Conical Flask — collects the filtrate beneath the funnel.
• Funnel Stand, Double — a free-standing wooden stand as an alternative support.

See more in the Chemistry Lab Equipment category.

Frequently Asked Questions

What funnel sizes does it hold?
The outer ring holds funnels of 3 to 6 inch diameter; with the removable inner lid fitted it holds smaller funnels of 1 to 3 inch diameter.

What is the difference between the single and double versions?
The single holder supports one funnel; the double holder supports two, so two filtrations can run at the same time.

Hoffman Voltameter (Product Code: SLE/CH/59) is a borosilicate glass electrolysis apparatus used to demonstrate the decomposition of water, to determine chemical composition by electrolysis, and to evaluate the electrochemical equivalent of hydrogen. Two connected limbs, each graduated for 50 cm³, rise from a central reservoir tube with a funnel-shaped bulb, and each limb has a stopcock at the top for drawing off and testing the collected gas. It comes with one pair of platinum electrodes and one pair of carbon electrodes. Schools, colleges and teacher-training labs use it as the standard electrolysis apparatus in India, and it is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala.

Specifications

Typical Use

For the electrolysis of water, the platinum electrodes are fitted and the apparatus is clamped upright. With both stopcocks open, water made conducting with a little dilute acid is poured into the funnel bulb until the limbs are full; the stopcocks are then closed and a low-voltage DC supply is connected. Gas collects at the top of each limb, and students can read the volumes on the graduations and see that the hydrogen volume is about twice the oxygen volume. Opening a stopcock lets them test each gas with a lighted or glowing splint. Recording the current and time alongside the volume of hydrogen allows the electrochemical equivalent of hydrogen to be worked out.

For the electrolysis of hydrochloric acid or ammonia solution, the carbon electrodes are used in place of platinum. Carry out these runs in a well-ventilated room or fume cupboard, keep flames away from collected hydrogen except during the controlled splint test, and rinse the glassware thoroughly with water afterwards. This apparatus is a mainstay of borosilicate laboratory glassware in India for chemistry and physics departments alike.

Retort Clamp Three Finger (Product Code: SLE/CH/60) is a three-prong clamp that holds round glassware — flasks, condensers, boiling tubes — steady on a support stand while it is heated, filled or connected to other apparatus. Its rubber-covered jaws close around articles up to 75 mm in diameter, which covers most of the glassware handled on school and college chemistry benches. The clamp is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, and is a routine part of any retort stand lab set-up in India and international markets.

Specifications

Typical Use

Teachers use this clamp to grip the neck of a flask above a burner during heating or simple distillation, to hold a condenser at the right angle, or to steady a boiling tube while a gas is prepared and collected. Because the jaws are driven by a twin screw, both sides close together and the glass stays centred rather than being pushed to one side, which reduces strain on the joint where tubing or a stopper is fitted.

The 15 cm rod is pushed into a boss head on the upright stand rod — the familiar lab stand, clamp and boss head arrangement — so the height and angle can be adjusted before any liquid is added. Tighten the pommels only until the rubber lining just grips; overtightening can crack thin-walled glass, and the rubber should be kept clear of the direct flame.

Manufacturer

ScienceLab is the trading name of Jain Scientific Equipments Private Limited, an Ambala, Haryana company that manufactures stand hardware, glassware accessories and teaching apparatus for schools, colleges and laboratories. Our company profile gives more background on the business and its product range.

Items usually ordered with a three finger clamp to complete the stand assembly:

• Boss Head — joins the clamp rod to the upright rod of the stand
• Retort Stand — the base and upright rod on which the clamp is mounted
• Retort Clamp Four Finger — the larger option for objects up to 100 mm
• Conical Flask — typical glassware held in the jaws
• Bunsen Burner — heat source placed below a clamped flask

See the wider Chemistry Lab Equipment range for stands, clamps and bench accessories.

Frequently Asked Questions

What size of glassware does this clamp hold?
Articles up to 75 mm in diameter. For wider vessels, choose the four finger version.

Can I choose the rod material?
Yes — the clamp is fitted with a 15 cm rod in either mild steel or aluminium. Mention your preference in the enquiry and we will confirm it in the quotation.

Is a boss head part of the clamp?
The listing covers the clamp with its rod. If your stands do not already have spare boss heads, add them to the same enquiry.

Will the jaws mark or crack glass?
The rubber covering cushions the glass, so marking is unlikely. Cracks usually come from overtightening or clamping glass that is still expanding with heat, so tighten gently and recheck after warming.

How should the clamp be looked after?

Retort Clamp Four Finger (Product Code: SLE/CH/61) is a strong, four-prong clamp for bigger vessels, holding objects up to 100 mm across securely on a support stand. Four cork-lined jaws spread the grip around the glass, and a plated brass tommy bar lets the user tighten it by hand without tools. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, for college and school laboratories that stock chemistry lab equipment in India and international markets. Note that it is supplied without a boss head.

Specifications

Typical Use

The four finger design is chosen when a three-prong clamp is too small or too narrow to hold the load safely: large round-bottom or distillation flasks, wide-necked bottles and gas-generating vessels that carry extra weight once filled. Four contact points hold the vessel squarely, so it is less likely to rotate in the jaws when tubing or a stopper is pushed into the neck.

Fit the 8 mm stem into a boss head on the stand rod — the usual lab stand, clamp and boss head combination — and set the height before the vessel is loaded. Cork lining gives a firm, slightly yielding contact on glass; turn the tommy bar until the cork just bites, and check again once the flask warms up. Keep the cork dry between sessions so it does not harden or crumble.

Frequently Asked Questions

Does the clamp come with a boss head?
No. It is supplied without one, so order a boss head for each clamp unless your stands already have spares.

What is the largest object it will hold?
Objects up to 100 mm. For smaller glassware, the three finger clamp is lighter and easier to position.

Why cork rather than rubber on the jaws?
Cork gives a secure, cushioned contact on glass. Keep it dry and replace worn lining before it loses grip.

Will the stem fit my existing boss heads?
The stem is 150 x 8 mm anodized aluminium. Check that your boss heads close firmly on an 8 mm rod, or ask us to match suitable ones.

Retort Rings (Product Code: SLE/CH/62) are cast iron support rings that lock onto the upright rod of a stand to carry a filter funnel, a separating funnel, a wire gauze or an evaporating dish at a chosen height. Each ring is cast with its own boss and a chrome-plated brass thumbscrew, so no separate connector is needed. The rings are made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, and form a basic part of retort stand lab work in India and international markets.

Specifications

Typical Use

In filtration practicals the ring holds a funnel above a beaker so the filtrate runs straight down. For solvent extraction it cradles a separating funnel, which is then easy to lift out and shake — the usual set-up whenever students use a separating funnel in an India lab syllabus. Set a wire gauze on the ring and it becomes a stand for heating a beaker or evaporating dish over a Bunsen flame.

Because the centre of every ring sits roughly 120 mm out from the rod, a burner fits underneath without the flame touching the stand rod. Two rings on one rod can hold a funnel above a gauze-supported receiver. Tighten the thumbscrew fully before loading, and place a gauze between flame and glass rather than resting glassware directly on the hot iron.

Manufacturer

These rings come from Jain Scientific Equipments Private Limited, which trades as ScienceLab and is based in Ambala, Haryana, where the company produces laboratory hardware and educational apparatus. Visit our company profile to learn more about the business.

Related Chemistry Lab Equipment

Apparatus used on or around a retort ring in filtration, extraction and heating work:

• Retort Stand — the upright rod that the ring clamps onto
• Gauze Wire — laid on the ring to spread burner heat under glassware
• Separatory Funnel — rests in the ring during liquid-liquid extraction
• Glass Funnel — supported in the ring for gravity filtration
• Bunsen Burner — heat source placed below the ring

The full Chemistry Lab Equipment section lists further stands, supports and heating accessories.

Frequently Asked Questions

Which stand rods does the ring fit?
Rods up to 13 mm in diameter. If your stands have thicker rods, tell us the diameter before ordering.

Do I need a separate boss head?
No. The ring is cast with its own boss and chrome-plated brass thumbscrew, so it clamps straight onto the rod.

What ring sizes can I order?
The ring is made in more than one size, all with the same approx. 120 mm offset from the rod. Contact us for the current size list.

Can glassware sit directly on the ring over a flame?
It is better not to. Put a wire gauze on the ring so heat spreads evenly and glass does not touch hot iron at a single point.

How do I keep the ring in good condition?
Wipe off spills once it has cooled, keep the thumbscrew thread free of deposits, and store rings dry to protect the painted finish.

Can you quote for a full set of stand hardware?
Yes. List the rings, stands, clamps and gauzes you need and we will quote them together for delivery across India and international markets.

Boss Head (Product Code: SLE/CH/63) is the connector block that locks a clamp rod to the upright rod of a laboratory stand, usually at right angles, so clamps and holders can be set at any height. Two vee grooves in the die-cast aluminium alloy body seat round rods accurately, and two chrome-plated thumb screws hold each rod firmly. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, in small and large sizes, and is a core item in every lab stand clamp boss head kit supplied in India and international markets.

Specifications

Typical Use

Any clamp with a plain stem — a retort clamp, thermometer clamp or condenser clamp — needs a boss head to attach it to a stand. One groove sits on the vertical stand rod and the other takes the clamp stem; each has its own thumb screw, so the clamp can be raised, lowered or swung round without taking the whole assembly apart. When planning a practical, count one boss head for every clamp that will be on the stand.

For a secure set-up, tighten the screw on the stand rod first, then position and tighten the clamp stem. Arrange the boss head so its open side faces up, allowing the load to press the rod into the groove rather than away from it. Schools replacing lost or worn fittings often order boss heads with other lab equipment accessories in one enquiry.

Manufacturer

ScienceLab is the brand of Jain Scientific Equipments Private Limited, based in Ambala, Haryana, which manufactures support-stand hardware alongside a broad range of teaching and laboratory apparatus. Our company profile describes the business in more detail.

Frequently Asked Questions

Should I order the small or the large size?
Choose the size that matches your stand rod and clamp stem diameters. Send us those two diameters through the contact page and we will recommend the right one.

How does it hold two rods at once?
The body has two vee grooves, each with its own chrome-plated thumb screw, so the stand rod and clamp stem are tightened independently.

Why vee grooves instead of round holes?
A vee seats a round rod along two lines of contact, which centres it accurately and gives a firm grip across a range of rod diameters.

Any tips for making it last?
Tighten by hand only — pliers can strip the thread in the aluminium body — and wipe chemical spills off the screws before storing.

How many boss heads does a class set need?
Usually one per clamp on each stand. Share your stand and clamp counts and we will size the order.

Do you handle tender and export orders?
Yes. We quote for schools, colleges and distributors throughout India and in international markets.

Burette Clamps (Product Code: SLE/CH/64) hold a burette straight and steady on a stand rod throughout a titration. The clamp is die-pressed from thick M.S. sheet and chrome plated; each burette sits in a V-groove and is pressed in place by a spring-loaded jaw, and the bosshead takes rods up to 18 mm in diameter. Versions for a single or a double burette are made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, for any burette clamp India lab requirement and for international markets.

Specifications

Typical Use

A burette that leans gives parallax errors at the meniscus and drips down the side of the flask, so a clamp that holds it truly vertical is basic to accurate acid-base, redox and complexometric titrations. The spring-loaded jaw lets a student slide the burette in or out for filling and rinsing without loosening a screw, while the V-grooves keep it aligned each time it is replaced.

The double version holds two burettes side by side — useful for back-titrations, for running a blank next to the sample, or for sharing one stand between two students. Mount the clamp high enough for a conical flask to swirl freely under the jet. Schools assembling a titration kit for school practicals in India typically pair this clamp with a stand, burette and flask for each bench.

Manufacturer

The clamp is produced by Jain Scientific Equipments Private Limited, trading as ScienceLab, an Ambala, Haryana manufacturer of titration hardware and laboratory apparatus for education and industry. Further information is on our company profile page.

Related Chemistry Lab Equipment

Everything else needed on a titration bench:

• Burette — the graduated tube the clamp holds
• Burette Stand and Funnel Stand — a support for the burette and filling funnel
• Retort Stand — a general stand whose rod the bosshead grips
• Conical Flask — the titration flask placed under the jet
• Brush Burette — for cleaning the burette between runs

Find more titration and stand apparatus in our Chemistry Lab Equipment category.

Frequently Asked Questions

Should I choose the single or double clamp?
Single suits one burette per stand. Double holds two burettes side by side, which helps with blanks, back-titrations or two students sharing a stand.

What rod diameter does the bosshead take?
Rods up to 18 mm in diameter, which covers most laboratory stand rods.

How does the clamp hold the burette without a screw on the glass?
The burette rests in a V-groove and a second jaw presses it in by spring force, giving steady pressure without point loading from a screw.

Is it strong enough for daily student use?
Yes — it is die-pressed from thick M.S. sheet and is non-breakable in normal use, with a chrome-plated finish.

How should it be cleaned after titrations?
Wipe acid or alkali splashes off promptly with a damp cloth and dry the clamp, so the plating stays in good condition.

What warranty applies?
Warranty terms are included in our quotation; contact us if you need them before placing an order.

Can you supply complete lab quantities or export orders?
Yes. We supply schools, colleges and distributors across India and international markets.

Burette Clamps Light Weight (Product Code: SLE/CH/65) are aluminium burette clamps that combine a light body with the mechanical strength needed for daily titration classes. Rubber-covered, spring-action jaws give a positive grip and quick release, and a single thumb screw fixes the clamp to a rod of nominal 13 mm diameter. Made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, they suit student benches where a light burette stand in an India lab is moved and reset often, and are also supplied to international markets.

Specifications

Typical Use

In a busy volumetric analysis class the clamp is opened and closed dozens of times a session as burettes are filled, read and rinsed. The spring-action jaws open with a squeeze of the rubber finger grippers and close again on their own, so students can change a burette with one hand while the other steadies the glass. The rubber covering protects the burette’s outer surface and graduations from metal contact.

Being aluminium, the clamp adds little weight at the top of a stand, which keeps lighter student stands stable when a full burette is fitted. It is a good match for teaching labs putting together a volumetric analysis kit for India schools and colleges, where the double version lets two burettes share one rod — for example one titrant and one blank.

Manufacturer

Jain Scientific Equipments Private Limited, trading as ScienceLab, is based in Ambala, Haryana and makes laboratory hardware and educational apparatus. It is registered as an MSME manufacturing enterprise (Udyam UDYAM-HR-01-0003714), and export consignments are shipped under Importer-Exporter Code AAECJ8618A issued by DGFT.

Test Tube Holder (Product Code: SLE/CH/66) is a hand-held clip for gripping a test tube while it is heated, shaken or poured, keeping fingers well away from the flame and the contents. It is formed from chrome-plated spring steel wire with finger grips, measures 130 mm overall, and its jaws take tubes up to 38 mm in diameter. The holder is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, and is standard issue for every student carrying out a salt analysis practical in school, in India and international markets.

Specifications

Typical Use

Dry-heating a salt, warming a solution to speed a reaction, and running preliminary tests for gases all involve holding a tube in or near a flame. Clip the holder near the mouth of the tube, keep the tube tilted and pointed away from yourself and others, and move it gently through the flame so the contents heat evenly and do not bump out. The wire collar keeps the two jaws lined up, so the tube does not twist loose as it is tilted.

The same holder is handy for dipping a tube into a hot water bath, or for carrying a warm tube back to the rack. In a flame test kit for school practicals in India, it is usually issued with a Bunsen burner or spirit lamp and a stand of clean tubes at each bench. After use, rest the holder on the bench rather than leaving it clipped to a hot tube.

Manufacturer

This holder is a product of Jain Scientific Equipments Private Limited of Ambala, Haryana, which uses the trading name ScienceLab for its laboratory apparatus and teaching equipment. Learn more on our company profile.

Related Chemistry Lab Equipment

Apparatus used alongside a test tube holder at the bench:

• Test Tube — the glassware the holder grips
• Bunsen Burner — the usual gas flame for heating tubes
• Glass Spirit Lamp — a flame source where gas is not available
• Test Tube Stand (Wire Pattern) — holds tubes upright before and after heating
• Brush Test Tube — for cleaning tubes after the practical

You can view other holders and racks in the Chemistry Lab Equipment range.

Frequently Asked Questions

What tube sizes does it hold?
The jaws accept tubes up to 38 mm in diameter, so standard school test tubes and wider boiling tubes are both covered.

Where on the tube should it be clipped?
Near the mouth, about a quarter of the way down, so most of the tube can be heated and your hand stays clear of the flame.

Does the handle get hot?
It is metal, so avoid holding it in the flame. The 130 mm length keeps the finger grips at a distance from the heated tube in normal use.

How do I keep it in good order?
Wipe off any chemical splashes, dry it after washing, and avoid prising the jaws wider than needed so the spring keeps its tension.

Can I order a set for a whole class?
Yes. Tell us the number of benches or students and we will quote a class quantity.

Do you ship outside India?
Yes, we supply institutions and distributors in India and international markets; contact us for export terms.

Pinch Clip (Product Code: SLE/CH/67) is a small clip that squeezes a length of flexible laboratory tubing flat, stopping the flow of liquid or gas through it until the clip is released. It works as a simple on/off valve on rubber or silicone tubing in burettes, siphons and gas apparatus. The clip is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, for school and college chemistry labs that build their own gas collection apparatus in India and international markets.

Key Details

Typical Use

On a simple burette made from a glass tube, a short piece of rubber tubing and a jet, the pinch clip takes the place of a stopcock: pressing it opens the tubing and lets titrant run, releasing it shuts the flow. In gas preparation, a clip on the delivery tubing holds the gas back while a gas jar is positioned, and it can seal off a side arm or siphon line when the apparatus is being dismantled.

A pinch clip gives quick on/off control. Where a steady, adjustable drip is needed, a screw clip is the better choice. Fit the clip on a straight, undamaged section of tubing, and move it slightly now and then so the rubber does not take a permanent crease. These clips are small and easily lost, so labs usually keep spares with their chemistry lab equipment consumables.

Manufacturer

ScienceLab is the trading name of Jain Scientific Equipments Private Limited, a manufacturer of laboratory fittings and educational apparatus located in Ambala, Haryana. See our company profile for details of the company.

Related Chemistry Lab Equipment

Tubing and apparatus that a pinch clip is normally used on:

• Rubber Tubing — the flexible tubing the clip closes
• Silicone Tube — an alternative tubing that also takes the clip
• Hoffman Screw Clip — for gradual, adjustable flow control
• Delivery Tube — carries gas to the collecting vessel
• Gas Jar, Glass — collects the gas released through the tubing

Explore further clips and fittings under Chemistry Lab Equipment.

Frequently Asked Questions

What tubing size does the clip fit?
We do not list a tubing size on this page. Send us the outer diameter and wall thickness of your tubing through the contact page and we will confirm a suitable clip.

How is a pinch clip different from a Hoffman screw clip?
A pinch clip is an open/shut control. A Hoffman screw clip closes the tubing progressively with a screw, so the flow rate can be set.

Is tubing included?
No, the clip is supplied on its own. Rubber or silicone tubing can be added to the same order.

Can it replace a burette stopcock?
On a rubber-tube burette, yes — that is one of its classic uses. Glass burettes with a built-in stopcock do not need it.

What is it made of, and are colours available?
Material and finish options are confirmed at the time of quotation; please ask if you have a specific requirement.

Can you supply clips in larger quantities?
Yes. We supply schools, colleges and distributors in India and international markets.

Heat Conductometer (Product Code: SLE/CH/68) is a classroom demonstration set for comparing how well different metals conduct heat. Five metal rods — aluminium, brass, iron, copper and stainless steel — are fitted radially on a brass disk, so heat applied at the centre travels out along all five at the same time and students can see which rod passes it on fastest. It comes with a Teacher’s Guide and is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, as a compact heat energy science kit for schools in India and international markets.

Specifications

Typical Use

A common method is to fix a small, equal bead of wax to the outer tip of each rod, support the set so the rods are level, and heat the central brass disk gently with a burner or spirit lamp. As heat is conducted outwards, the wax beads soften and drop one after another; the order in which they fall ranks the five metals by conductivity. Because every rod has the same 75 mm length and 5 mm diameter, the comparison is fair and the only variable is the metal itself.

The set fits lessons introducing the properties of different elements as well as thermodynamics topics on conduction, and it works as a physics experiment kit for school classes as much as in chemistry. Students can extend the activity by reading the rod tips with an infra-red thermometer at fixed intervals. Let the disk and rods cool completely before handling them or removing wax.

Manufacturer

The Heat Conductometer is made by Jain Scientific Equipments Private Limited, known by its trading name ScienceLab, which designs and manufactures science demonstration apparatus in Ambala, Haryana. Our company profile has more about the company.

Related Laboratory Equipment

Useful additions for a lesson on heat conduction:

• Apparatus Heat/Thermal Conductivity — a further apparatus for conductivity experiments
• Heat Transfer Kit — extends the topic to other modes of heat transfer
• Bunsen Burner — a heat source for the central disk
• Thermometer, Infra Red, Hand Held — measures rod-tip temperatures without contact
• Wax — for the melting-bead method on the rod tips

More demonstration apparatus is listed in Chemistry Lab Equipment.

Frequently Asked Questions

Which metals are included?
Five rods: aluminium, brass, iron, copper and stainless steel, all fitted on one brass disk.

What comes in the set?
The rod-and-disk assembly and a Teacher’s Guide. A heat source and wax are not part of the listing and can be ordered separately.

What are the dimensions?
Each rod is 75 mm long and 5 mm in diameter; the brass disk is 27 mm in diameter.

Which rod should conduct heat fastest?
In general, copper conducts heat best of these metals and stainless steel least. Let students observe and record the order before telling them the answer.

How do I clean it after the practical?
Once cool, lift off wax residue with a cloth or warm water, then dry the rods fully.

Is it available for bulk or export orders?
Yes. We supply institutions and distributors in India and international markets; contact us with the number of sets required.

MCT Twin Rack (Product Code: SLE/CH/69) is a two-sided rack for microcentrifuge tubes (MCTs): one face holds 0.5 ml tubes and the other holds 1.5 ml tubes, with 108 holes on each side. An alphanumeric index on each face of the base identifies every position, and a transparent top gives a clear view while protecting the stored tubes. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, for molecular biology, biotechnology and clinical teaching labs that source from a lab plastic ware supplier in India, and for international markets.

Specifications

Typical Use

During DNA extraction, enzyme digests or sample aliquoting, tubes move constantly between the bench, a laboratory centrifuge and the freezer. Keeping them in an indexed rack means each sample has a recorded address — for example a row letter and column number — so nothing is mixed up when the lids all look the same. When the day’s work switches from 1.5 ml tubes to smaller 0.5 ml tubes, simply turn the rack over instead of reaching for a second rack.

With the transparent top in place, tubes can be checked for labels and volumes without being lifted out, and they stay covered while waiting for the next step. Note the index position of each sample in the lab notebook before loading, and keep the rack level when moving it so open tubes do not spill.

Manufacturer

ScienceLab is the trading name of Jain Scientific Equipments Private Limited, an Ambala, Haryana manufacturer of laboratory plasticware, racks and teaching apparatus. For institutional buyers completing vendor forms, the company’s GSTIN is 06AAECJ8618A1ZT and its Legal Entity Identifier (LEI) is 3358004HRD1JIVXKYX49. See our company profile for more.

Micro Test Plates (Product Code: SLE/CH/71) are multi-well plates used to run many small-volume tests side by side, most often ELISA (enzyme-linked immunosorbent assay) work in immunology, microbiology and biotechnology labs. They are offered in two formats — a Flat Bottom ELISA Plate and a U Bottom ELISA Plate — and are supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, as part of its range for laboratories that need a lab consumables supplier in India and international markets.

Key Details

Typical Use

The well shape decides which plate to pick. Flat bottom wells give an even liquid layer that a plate reader can measure optically, so they are the usual choice when colour development in an ELISA is read as absorbance. U bottom wells collect small volumes at the centre, which helps with mixing, dilution series, and tests where a settled button or even film is judged by eye.

In practice, samples and reagents are pipetted into the wells with a micropipette, the plate is incubated and washed between steps, and results are read well by well. Since fresh plates are normally used for each assay run, many labs keep them on the same reorder list as tips and other disposable lab equipment in India. Label the plate edge and record the well layout before starting, so every result can be traced back to its sample.

Supplier

Micro Test Plates are supplied by Jain Scientific Equipments Private Limited, which trades as ScienceLab from Ambala, Haryana, and also manufactures laboratory and teaching apparatus. Read more about the company on our company profile.

Related Laboratory Equipment

Instruments and accessories used in the same plate-based workflow:

• ELISA Reader 8 Channel — reads absorbance of the developed wells
• ELISA Washer 8 Channel — for the wash steps between reagents
• Micropipette — dispenses samples and reagents into each well
• Micropipette Tips — fresh tips between samples
• Micro Tip Box — keeps tips racked and ready at the bench

For more lab supplies, visit the Chemistry Lab Equipment category.

Frequently Asked Questions

Should I choose flat bottom or U bottom?
Choose flat bottom when results will be read in a plate reader; choose U bottom for mixing, dilutions and visual end-points in small volumes.

How many wells does each plate have?
The well count is not listed on this page. Contact us and we will confirm the format before you order.

Will the plates fit my ELISA reader?
Plate readers take plates of a set footprint. Send us your reader model and we will check compatibility.

Can the plates be reused?
ELISA plates are normally used once, because coated or stained wells are difficult to clean reliably. Ask us if you need guidance for a specific assay.

What pack sizes are available?
Pack quantities are given in the quotation. Tell us your monthly usage and we can suggest a sensible order size.

Do you supply laboratories outside India?
Yes. We supply institutions and distributors in India and international markets.

PCR Tube Rack (Product Code: SLE/CH/70) keeps PCR tubes upright and in order while reactions are set up, loaded and stored. Its top and base are made of tough, transparent polycarbonate with a polypropylene middle section, and the tube positions are spaced uniformly so a multipipette can fill a whole row at once. Several racks stack together to save shelf space. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, for teaching and research labs buying PCR equipment in India and international markets.

Specifications

Typical Use

Setting up a PCR means adding master mix, primers and template to a row of small tubes in exactly the same way. Even spacing lets a multichannel pipette line up with a full row, which speeds up loading and cuts down on missed or doubled wells. The clear polycarbonate top and base let you see the tubes and their liquid levels from above and below, so a quick glance confirms every tube has been filled before it goes into the thermal cycler.

Between runs, stack the loaded or empty racks to keep the bench and cold-store shelves tidy. A rack per student group keeps samples separate in practical classes, and labs that source from a lab plastic ware supplier in India often order these racks with tubes and tips so each workstation is equipped the same way.

Micro Tip Box (Product Code: SLE/CH/72) is a racked, lidded box that holds micropipette tips upright so they can be picked up directly on the pipette shaft without being touched by hand. Two capacities are offered: one box takes 96 micro tips of 2-200 µl and the other takes 100 micro tips of 200-1000 µl. The box is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, for biology, biotechnology and analytical labs that buy from a lab plastic ware supplier in India, and for international markets.

Specifications

Typical Use

Loose tips in a bag are easily contaminated and slow to fit. In a tip box each tip stands in its own hole, so the user presses the pipette straight down onto a tip and lifts it out without contact from gloves or fingers. Keep the lid closed between uses to keep dust out, and work across the box row by row so partly used boxes are easy to top up.

Match the box to the pipette on the bench: the 2-200 µl box for small-volume work such as reagent additions and ELISA loading, and the 200-1000 µl box for larger transfers and dilutions. Labs usually keep a filled box for each pipette and refill from bulk tips, so repeat orders to a lab consumables supplier in India stay simple and predictable.

Manufacturer

Jain Scientific Equipments Private Limited is the company behind the ScienceLab brand; from its base in Ambala, Haryana it produces laboratory plasticware, instruments and educational apparatus. The company profile gives an overview of its work.

Universal Multi Rack (Product Code: SLE/CH/73) is a single rack that holds four different test tube sizes, so narrow tubes, standard tubes and wide tubes can share one compact footprint on the bench or in a cupboard. It is made from thick, sturdy plastic and designed for efficient storage. The rack is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, and is a practical test tube rack for school labs in India and international markets where mixed tube sizes are in daily use.

Specifications

Typical Use

Most practicals use more than one kind of tube — small tubes for spot reactions, standard test tubes for qualitative tests, larger tubes for heating or culture work. Instead of setting out several racks, one Universal Multi Rack keeps the whole set together, which frees bench space and makes it easier to see at a glance whether every tube has been returned after class.

The 40 small positions suit a full set of narrow tubes for a class demonstration, while the eight large positions take wide tubes or small bottles. Place the rack on a level surface away from the burner, and let hot tubes cool a little before standing them in the plastic. Labs that buy from a lab plastic ware supplier in India often pair it with single-size racks for bulk tube storage.

Cuvettes, Plastic (Product Code: SLE/CH/74) are small, clear-walled sample cells that hold a liquid in the light beam of a colorimeter or spectrophotometer, so its colour or absorbance can be measured. They are used in school, college and research labs for concentration measurements, reaction-rate studies and biochemical assays. These cuvettes are supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, for labs that rely on a chemistry consumables supplier in India and international markets.

Key Details

Typical Use

A classic practical is plotting a calibration line for a coloured solution such as copper sulphate: a blank cuvette of solvent sets the zero, then standards of known concentration are read one after another, and an unknown is measured against the resulting graph. Cuvettes are equally useful for following a colour change over time in rate experiments, or for reading enzyme and protein assays in biology and biochemistry.

Hold a cuvette only by the faces that are not in the light path, fill it to a consistent level, and wipe the clear faces with lint-free tissue before inserting it. Turn it the same way round in the holder every time. Plastic cuvettes are generally chosen for visible-light work; check with us before using them for UV measurements. Most labs keep a stock of them alongside other items from a lab consumables supplier in India.

The Open Manometer (Product Code: SLE/CH/75) is a borosilicate glass manometer tube with a long 50 cm arm and a funnel top, offered as the replacement tube for an open-type manometer. It turns an invisible pressure difference into a visible difference in liquid level, which is why teachers in school and college laboratories use it for practicals on gas and liquid pressure. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, as part of its chemistry lab equipment in India for schools, colleges and distributors.

Specifications

Typical Use

An open manometer compares a pressure with the atmosphere: one side is connected to the source under test while the other stays open to the air, and the gap between the two liquid levels shows how far the pressure is above or below atmospheric. The funnel top lets students pour in the liquid without spilling, and the 50 cm arm leaves enough height for a level difference that the whole class can read during demonstrations of gas supply pressure, breath pressure or pressure below a liquid surface.

For a steady reading, clamp the tube upright on a retort stand, tint the water with a few drops of food colouring, and connect the source with a short length of rubber tubing. Borosilicate laboratory glassware is chosen for its resistance to common laboratory chemicals and repeated washing; rinse the tube after each session and store it with the long arm supported so it cannot be knocked or bent under its own weight.

Manufacturer

This tube is produced by Jain Scientific Equipments Private Limited, which trades as ScienceLab and is based in Ambala, Haryana, India. The company makes laboratory glassware and teaching apparatus for educational institutions and distributors; read more on the company profile page.

Related Laboratory Equipment

Items usually set up alongside an open manometer for pressure demonstrations:

• Manometer, Glass — a complete glass manometer for physics pressure measurement
• U Tube Manometer — an alternative U-tube design for comparing two pressures
• Rubber Tube (Laboratory) — flexible tubing to connect the manometer to the source under test
• Retort Stand — holds the long arm vertical so levels are read correctly
• Food Colouring Blue — tints the water so the liquid levels stand out

See the complete Chemistry Lab Equipment range for more glassware, clamps and supports.

The Steam Trap (Water Trap) (Product Code: SLE/CH/76) is a standard component fitted into laboratory glassware set-ups to discharge condensate and non-condensable gases from a steam line. By catching the water that forms as steam cools in the connecting tubing, it keeps the flow of steam to the next vessel steady and stops that vessel from slowly flooding. Chemistry teachers, college demonstrators and research technicians use it when assembling steam distillation trains and similar laboratory distillation apparatus in India. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala.

Key Details

Typical Use

In steam distillation, steam produced in one flask travels through tubing into a second flask that holds the mixture being separated. Some of that steam condenses on the way, and without a trap the water collects in the distilling flask and dilutes the charge. Placed between the steam source and the distilling flask, the trap separates this condensate, and also lets air and other gases that will not condense leave the line so the steam flow is not interrupted.

Mount the trap at a low point of the steam line so condensate drains into it naturally, keep the connecting tubing short, and empty the collected water between runs. Students should handle it with care once the set-up is hot, because steam burns can occur even when the glass looks clear. Pairing a trap with a Liebig condenser and a two-neck round bottom flask gives a complete, classroom-friendly distillation train.

Manufacturer

ScienceLab is the brand name of Jain Scientific Equipments Private Limited, a manufacturer of laboratory and teaching equipment located in Ambala, Haryana, India. Details of the company and its product lines are available on our company profile.

• Distillation Apparatus — the core distillation set into which the steam line feeds
• Fractional Distillation Assembly — for separating liquids with closer boiling points
• Liebig Condenser — condenses the distillate after the distilling flask
• Round Bottom Flask With Two Neck — allows steam inlet and vapour outlet on one flask
• Silicone Tube — flexible tubing for connecting the steam line

Browse all Chemistry Lab Equipment for further glassware and accessories.

Frequently Asked Questions

What does a steam trap do in a glassware set-up?
It removes condensate and non-condensable gases from the steam line, so mostly steam reaches the next vessel and the flow remains steady.

Where should it be placed?
Between the steam generator and the flask receiving the steam, ideally at a low point so the condensed water runs into it.

What size and joint type is it?
Dimensions, material details and connection type are not stated in our current listing. Please contact us with details of your apparatus so we can confirm a compatible trap.

Is it suitable for school practicals?
Yes, it is a standard item for glassware set-ups and suits supervised school and college distillation work.

The Capillary Tube Set (Product Code: SLE/CH/77) is a ready-mounted demonstration piece in which 4 glass capillary tubes of different inner diameters rise from a common, larger reservoir tube. Pour in a liquid and the class sees at once that it climbs highest in the narrowest bore, giving students the evidence they need to draw their own conclusions about capillary action. Designed for middle-school and secondary science teachers, it is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, and arrives on its own stand with a Teacher’s Guide.

Specifications

Typical Use

Because all four capillaries share one reservoir, the liquid starts at the same level in each, so any height difference can only come from the tube width. That makes the set a clear, fair-test capillary tube experiment: students record the level in each tube, rank them by bore, and relate the result to adhesion between water and glass and to surface tension. The same observation helps explain how water rises through soil, paper towels and the xylem of plants, linking chemistry and physics lessons to biology.

Stand the set on a level bench, fill the reservoir slowly so no air bubbles lodge in the narrow tubes, and add a drop of food colouring so the columns can be seen from the back of the room. Comparing plain water with soapy water is a simple extension that shows how lowering surface tension changes the rise.

Manufacturer

The set is made by Jain Scientific Equipments Private Limited, trading as ScienceLab, from its base in Ambala, Haryana, India, where it produces glass apparatus and demonstration equipment for science teaching. The company is a registered MSME enterprise (Udyam UDYAM-HR-01-0003714) and holds Importer-Exporter Code AAECJ8618A from the Directorate General of Foreign Trade for export consignments. Visit the company profile to learn more.

Related Laboratory Equipment

Useful additions for capillarity and surface-tension lessons:

• Food Colouring Red — colours the water so each liquid column is easy to read
• Dropper Bottle, 10 ml — for adding colouring or detergent a drop at a time
• Capillary Tube Apparatus — a physics set-up for measuring capillary rise in more detail
• Set of Capillary Tubes — loose capillaries for student group work

More demonstration apparatus is listed under Chemistry Lab Equipment.

Frequently Asked Questions

How many capillary tubes are in the set?
Four glass capillary tubes, each with a different inner diameter, rising from one larger reservoir tube.

Does it need a separate stand?
No. The set comes mounted on its own stand, so it can be placed directly on the bench.

Is teaching guidance included?
Yes, a Teacher’s Guide is supplied with the set to help plan the demonstration and discussion.

What liquid works best?
Coloured water is ideal for classrooms. Avoid leaving coloured or sugary liquids to dry inside the narrow tubes, as residue can block them.

How do I clean the capillaries?
Flush the reservoir with clean water several times so fresh water rises through each capillary, then let the set drain and dry upright.

Can you supply sets for every lab in a school group?
Yes, bulk orders for schools, colleges and distributors in India and international markets are welcome — share quantities through our contact page.

What about warranty on the glass parts?
Warranty terms are confirmed at quotation. Contact us for details.

Red Litmus Paper (Product Code: SLE/CH/78) is an indicator test strip used to show whether a solution is alkaline in introductory acid–base lessons in school and college chemistry laboratories. The easy-to-use strips turn blue when dipped into an alkaline or basic solution and come 100 strips per vial, a staple among litmus paper for school labs in India. They are supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

Specifications

What Is Red Litmus Paper Used For?

Red litmus answers one question: is this sample a base? Students touch a strip with a drop of the test liquid on a clean glass rod, and a blue patch confirms an alkaline solution such as soap water, lime water or a solution of baking soda. If the strip stays red, the sample is either acidic or neutral, which is why teachers pair it with blue litmus in an acid base indicator activity to sort samples into all three groups. Moistened red litmus held at the mouth of a test tube is also the classic check for alkaline gases such as ammonia.

Tear strips in half to make a vial last through more lab sessions, use a fresh piece for every sample, and keep the vial tightly closed and away from bottles of ammonia or other alkalis, because vapours in the air can turn unused strips blue. Handle strips with dry fingers or forceps so moisture does not spoil the rest of the vial.

Supplier

Red Litmus Paper is supplied by Jain Scientific Equipments Private Limited, which trades as ScienceLab from Ambala, Haryana, India. Indicator papers and other chemistry consumables are sourced for schools, colleges and distributors and can be quoted together with laboratory apparatus for India and international markets. Find out more on the company profile.

Items used in the same acid–base testing activities:

• Blue Litmus Paper — the partner strip that identifies acids
• Paper, Universal, pH 1-14 — shows how strongly acidic or basic a sample is
• Stirring Rod, Glass — transfers a single drop of sample onto the strip
• Dropper Bottle, 10 ml — holds test solutions at each student station
• Magnesium Ribbon — burn it and test the dissolved ash with red litmus to show a basic oxide

The full Chemistry Lab Equipment range has more indicators and bench tools.

Frequently Asked Questions

How many strips are in one vial of Red Litmus Paper?
Each vial of Red Litmus Paper contains 100 strips. Tearing strips in half stretches a vial across more practical sessions, so tell us how many vials each lab needs when you request a quotation.

What does a colour change on Red Litmus Paper mean?
A change from red to blue on Red Litmus Paper means the sample is alkaline (basic). If the strip stays red, the sample is either acidic or neutral, and blue litmus paper is then used to tell those two apart.

Can Red Litmus Paper give a pH value?
No. Red Litmus Paper only shows whether a sample is basic; it does not indicate how strongly acidic or alkaline it is. For an approximate pH number, use universal indicator paper or solution read against a pH chart.

Can Red Litmus Paper detect gases?
Yes. When moistened with distilled water, Red Litmus Paper responds to alkaline gases, and holding it at the mouth of a test tube to detect ammonia is the common example in school salt analysis.

What is the shelf life of Red Litmus Paper?
Shelf life depends on the chemical, its grade and storage conditions, so no blanket period is given for Red Litmus Paper. Ask us for the expiry date of the batch you are quoted, and keep vials closed, dry and away from ammonia fumes.

Who supplies Red Litmus Paper?
Red Litmus Paper is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, Haryana, India, in vials of 100 strips, for schools, colleges and distributors in India and international markets, alongside other indicators and chemistry consumables.

Blue Litmus Paper (Product Code: SLE/CH/79) is a vial of easy-to-use indicator strips that turn red when dipped into an acidic solution. Students in their first acids-and-bases unit use it to confirm that vinegar, lemon juice or a dilute mineral acid really is acidic, and laboratory staff keep it on hand as a fast pH indicator paper for spotting acid spills and residues. Each vial holds 100 strips, supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala.

Specifications

Typical Use

A common starter practical gives each group a tray of household and laboratory liquids and asks them to find the acids. A strip that turns red identifies an acid; a strip that stays blue tells students the sample is neutral or basic, and a second test with red litmus separates those two. Moistened blue litmus also responds to acidic gases, so it is used during gas tests in qualitative analysis, for example over a test tube releasing hydrogen chloride.

Place a strip on a white tile and add the sample with a clean dropper or glass rod rather than dipping the whole strip into a stock bottle, which avoids contaminating reagents. Store vials capped and well away from acid bottles, as acidic fumes in a busy lab can redden strips before they are used. For a class set, a single vial can be shared between several groups by cutting strips into shorter pieces.

Supplier

Blue Litmus Paper is supplied by Jain Scientific Equipments Private Limited under its trading name ScienceLab. The company is based in Ambala, Haryana, India, and equips school and college laboratories; more is on our company profile.

• Blue Litmus Solution — the liquid indicator form for test-tube work
• Dropper Bottle, Clear — dispenses samples a drop at a time
• Test Tube Racks — keeps labelled sample tubes upright during testing

Explore more indicators and glassware in Chemistry Lab Equipment.

Frequently Asked Questions

What colour change shows an acid?
The strip turns from blue to red when the sample is acidic.

What if the strip does not change colour?
The sample is neutral or basic. Test it with red litmus paper, which turns blue for bases.

How many strips does a vial contain?
100 strips per vial.

Is blue litmus paper enough to measure pH?
No, it only tells you whether a sample is acidic. Universal indicator paper gives an approximate pH value.

Why have some strips turned red in the vial?
They have been exposed to acidic fumes or moisture. Keep the vial closed and stored away from acids.

What should an institutional enquiry include?

Pascal's Principle Demonstrator (Product Code: SLE/CH/80) is a glass-bulb and piston apparatus used to show that pressure applied to a confined liquid is transmitted equally in all directions, in school physics lessons. Teachers fill it with water and push the piston, and jets squirt out of every hole in the 50 mm borosilicate bulb with equal reach. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India, as part of its physics lab equipment range.

Specifications

What Is the Pascal's Principle Demonstrator Used For?

It is the quickest way to introduce fluid pressure before moving on to hydraulic lifts, car brakes and hydraulic presses, which all rely on the same principle. Ask the class to predict whether water will leave only the hole in line with the piston; when every jet emerges with the same reach, they have seen for themselves that pressure acts equally throughout the liquid. Older students can then link the demonstration to calculations of force and area, and schools building up their physics lab equipment in India often teach it alongside buoyancy and manometer work.

Carry out the demonstration over a sink or a large tray, because water sprays in several directions at once. Press the piston smoothly rather than forcefully so the glass bulb is not stressed, and hold the unit so the jets point away from observers. Empty and dry the demonstrator after use so no water is left standing in the bulb.

OEM Manufacturer

ScienceLab is the trading name of Jain Scientific Equipments Private Limited, the OEM (original equipment manufacturer) of this demonstrator. The apparatus is made and assembled at the company's own licensed factory at Saha, Ambala, Haryana, India, rather than bought in from a trader. Schools, colleges, institutions, dealers and importers are supplied factory-direct, so questions about a replacement bulb or other spare parts go straight to the maker — just ask us. Read more on our company profile.

Related Laboratory Equipment

Other apparatus for a unit on pressure in fluids:

• Pascal's Sphere — a hollow sphere with nozzles and a hand pump, an alternative design for the same law
• Set to Demonstrate Archimedes’ Principle/Law — the natural next lesson on buoyancy
• Bernoulli Tube Apparatus — extends the topic to pressure in moving fluids
• Manometer, Glass — lets students measure pressure differences in liquids

Further apparatus is listed in our Chemistry Lab Equipment category.

Frequently Asked Questions

What does the Pascal's Principle Demonstrator show?
The Pascal's Principle Demonstrator shows Pascal's law: pressure applied to a confined liquid is transmitted equally in every direction. When the piston is pushed, water leaves every hole in the glass bulb with the same force, so students see the principle at a glance.

How big is the Pascal's Principle Demonstrator?
The Pascal's Principle Demonstrator has a borosilicate glass bulb 50 mm (2 in) in diameter, and the complete unit stands approx. 250 mm (10 in) high, compact enough for a front-bench demonstration in an ordinary classroom.

Does it need power or extra accessories?
No. The Pascal's Principle Demonstrator works by hand: fill it with water and push the piston. The only extras needed are water and a sink or large tray to catch the jets, because water sprays out in several directions at once.

Can students operate it themselves?
Yes, under teacher supervision. Students can push the piston of the Pascal's Principle Demonstrator themselves, but remind them to press smoothly rather than forcefully, because the bulb is glass, and to aim the jets away from other people.

Who manufactures the Pascal's Principle Demonstrator?
Jain Scientific Equipments Private Limited (ScienceLab) is the OEM that manufactures the Pascal's Principle Demonstrator at its own factory in Saha, Ambala, Haryana, India, and supplies it factory-direct to schools, colleges, dealers and importers in India and international markets.

Can I get a replacement glass bulb?
Ask us. Because ScienceLab manufactures the Pascal's Principle Demonstrator itself, requests for a replacement bulb or other spare parts go straight to the maker; quote product code SLE/CH/80 on our contact page and we will confirm what can be supplied.

What should a quotation request include?
For a quotation on the Pascal's Principle Demonstrator, give the product code SLE/CH/80, the number of units, any other fluid-pressure apparatus wanted on the same order, and the delivery location in India or abroad.

Magnesium Ribbon (Product Code: SLE/CH/82) is a thin strip of magnesium metal, 0.03 mm (0.0012 in) thick, used for combustion experiments and to demonstrate the principles of chemical change. When a short piece is lit it burns with a dazzling white flame and leaves a white powder that is clearly a new substance — the classic opening experiment for chemical reactions in secondary science. It is a flammable solid and is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, alongside the other lab chemicals and consumables schools order from us.

Specifications

Typical Use

In the standard practical, students clean a few centimetres of ribbon with sandpaper to remove the dull oxide coating, grip it with crucible tongs and hold it in a Bunsen flame. It ignites and burns brightly, forming magnesium oxide; dissolving that ash in a little water and testing it with red litmus shows the oxide of a metal is basic. The same ribbon is used to compare the reactivity of metals with dilute acids, where the fizzing of hydrogen gives a visible sign of reaction.

Safety matters with this flammable solid: tell students not to stare directly at the burning metal, carry out burning over a heat-resistant mat, and wear safety goggles. Never try to put out burning magnesium with water — let it burn out or smother it with dry sand. Store the ribbon in a closed container, in a cool dry place away from open flames and oxidising chemicals.

Frequently Asked Questions

How thick is the ribbon?
It is 0.03 mm (0.0012 in) thick.

How much ribbon is in one pack?
Pack length or weight is not stated in our current listing. Contact us and we will confirm the pack sizes available.

Why does the ribbon sometimes fail to light?
Magnesium develops a thin oxide coating in air. Rub it with sandpaper until it is shiny before holding it in the flame.

Is it safe for school use?
Yes, with supervision and eye protection. It is classed as a flammable solid, so keep it away from flames when not in use and never use water on burning magnesium.

How should it be stored?
In a closed container in a cool, dry chemical store, separate from oxidising agents.

Can you ship it internationally?
Because it is a flammable solid, transport is regulated. We supply customers in India and international markets, but shipping options must be confirmed with us before an export order is placed.

The Electrode, Carbon, Pair (Product Code: SLE/CH/83) is a set of carbon electrodes designed as replacement parts for the Hoffman Electrolysis Apparatus. Each pair comes with insulated lead wires and stoppers, so a laboratory can restore a voltameter whose electrodes have worn or broken without replacing the whole glass assembly. It is used by chemistry teachers and lab assistants maintaining electrolysis apparatus in India and overseas, and is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala.

Specifications

Typical Use

In a Hoffman voltameter the electrodes sit at the bottom of the two side limbs, sealed in by stoppers, while the gases produced collect above them. Carbon is chosen because it conducts well yet does not dissolve in most electrolytes, which makes it well suited to electrolysing salt solutions such as brine, where the chlorine released at the anode would attack many metal electrodes. Students can then measure gas volumes in each limb and relate them to the ions discharged at each electrode.

To fit a new pair, drain and rinse the apparatus, push each stopper firmly into its limb so it seals without leaking, and route the insulated leads to a low-voltage DC supply, noting which electrode is the anode. Carbon anodes slowly wear during long oxygen-producing runs, so keeping a spare pair among your lab equipment spare parts avoids cancelled practicals. After use, rinse the electrodes with distilled water and let them dry before storage.

Manufacturer

These electrodes are made by Jain Scientific Equipments Private Limited, known by its trading name ScienceLab, headquartered in Ambala, Haryana, India. The company supplies complete apparatus as well as the spares that keep it running; see our company profile.
