Stand With Base Plate H-Shape (Product Code: SLE/LR/12) is a heavy laboratory stand with an H-shaped cast iron base plate, used to carry tall or heavy apparatus such as distillation columns, reflux condensers and large flasks in college, university and research labs. It weighs 8.5 kg, is listed at 420 × 400 × 1000 (length × width × height), and includes one 18/10 stainless steel rod of 1000 × 16 mm with a washer and nut. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India, for distillation apparatus set-ups in Indian labs.

Specifications

What Is the H-Shape Base Plate Stand Used For?

A 1000 mm rod needs a wide, heavy footing, and that is what the 420 × 400 H-shaped plate and its 8.5 kg of cast iron provide. The stand is chosen for work that would topple a small base: fractional distillation with a long column, Soxhlet extraction, reflux under a condenser, or several clamps stacked up one rod. The 16 mm stainless rod is thick enough to resist bending when those clamps carry glassware well above the bench.

Fix the rod firmly with the included washer and nut before loading, then keep the heaviest vessel low and above the plate. The open centre of the H leaves room to place a heating mantle, burner or lab jack under the flask. Wipe the rod and plate after work; stainless steel resists rust but spilled reagents should not be left to dry on the cast iron.

What to Specify When Ordering

• The number of stands needed.
• Bossheads and clamps suited to a 16 mm rod, if you need them.
• Any spare or longer rods for the same stand.
• The delivery location, in India or abroad.

Tripods (Product Code: SLE/LR/13) are three-legged laboratory tripods used to hold a wire gauze, pipeclay triangle or vessel above a Bunsen burner for heating in school, college and research labs. Two constructions are offered, 18/10 stainless steel with welded feet and zinc-coated tempered cast iron with screwed feet, each in four sizes from D/Ø 100 to 160. They are made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India, as everyday laboratory instruments for India's teaching labs.

Specifications

What Are Laboratory Tripods Used For?

A tripod is the classic heating support: the burner goes underneath, a wire gauze or pipeclay triangle rests on the ring, and a beaker, evaporating dish or crucible sits on top. Students use it to boil water, evaporate solutions to crystals, heat crucibles to constant mass and run simple calorimetry. The A dimension (listed as length) and the D/Ø value let you match the tripod to the height of your burner flame and the size of the vessel.

Choose stainless steel with welded feet where hygiene, corrosion and easy cleaning matter, and zinc-coated tempered cast iron with screwed feet for robust everyday class use. Let a tripod cool before moving it, keep it on a heat-resistant mat, and never place a vessel directly over a bare flame without a gauze when the glass needs even heating.

What to Specify When Ordering

• The material: 18/10 stainless steel (welded feet) or tempered cast iron (screwed feet).
• The size by A and D/Ø from the lists above.
• The quantity, usually one per heating station.
• Whether gauzes, pipeclay triangles or burners should be quoted too.

OEM Manufacturer

Jain Scientific Equipments Private Limited trades as ScienceLab and makes these Tripods as the OEM (original equipment manufacturer) at its own licensed factory at Saha, Ambala, Haryana, India. For vendor registration on tenders, the company's details are GSTIN 06AAECJ8618A1ZT and Legal Entity Identifier 3358004HRD1JIVXKYX49.

Schools, colleges, dealers and importers buy the tripods factory-direct; ask us for repeat orders in a matching size. More on the company is on the ScienceLab profile.

Related Stand Bases, Rods and Rings

What goes on, under and beside a heating tripod:

• Gauze Wire — rests on the tripod ring to spread the flame under glassware.
• Pipeclay Triangle — holds a crucible on the tripod for strong heating.
• Bunsen Burner — the heat source placed between the legs.
• Crucible with lid — heated on the triangle for ignition and constant-mass work.
• Tripod Cast Iron Varnished — a threaded tripod stand base for a support rod, a different job.

Browse the Stand Bases, Rods and Rings category or the Burners category.

Frequently Asked Questions

What materials are the ScienceLab Tripods made in?
The Tripods are made in two versions: 18/10 stainless steel with welded feet, and tempered cast iron with a zinc coating and screwed feet. Both hold a gauze or triangle over a burner; stainless is easier to keep clean.

What sizes do the Tripods come in?
The stainless Tripods are listed as 180 × 100, 210 × 120, 210 × 140 and 240 × 160 (A × D/Ø). The cast iron Tripods are 180 × 100, 210 × 120, 210 × 140 and 240 × 150.

What is the difference between welded and screwed feet?
On the stainless steel Tripods the feet are welded, giving permanent joints with no threads to loosen. On the cast iron Tripods the feet are screwed in, so a leg that works loose can simply be tightened again.

What else do I need to heat with a tripod?
To heat with these Tripods you need a burner underneath and a wire gauze for beakers or flasks, or a pipeclay triangle for crucibles. We can quote gauzes, triangles and burners together with the tripods.

Who manufactures the Tripods?
The Tripods are manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), the OEM, at its own licensed factory at Saha, Ambala, Haryana, India. Institutions and dealers buy directly from the manufacturer.

How are these Tripods different from the Tripod Cast Iron Varnished?
These Tripods are heating supports that carry a gauze or triangle over a burner. The Tripod Cast Iron Varnished is a stand base with a thread that takes a support rod for clamps, so it serves a different purpose.

Rods For Stand Bases (Product Code: SLE/LR/14) are unthreaded 18/10 stainless steel support rods used to build retort stands and clamp set-ups on bases, feet, frames and table clamps in school, college and research laboratories. They are listed in lengths from 500 to 1500 and in three diameters, D/Ø 12, 13 and 16, giving fifteen size combinations to match the fitting and the height of the apparatus. They are made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India, and serve as new or spare rods for labs across India.

Specifications

What Are Rods for Stand Bases Used For?

The rod is the backbone of every retort stand: bossheads slide onto it and carry clamps, rings and holders at whatever height the experiment needs. Because these rods have no thread, they are made for fittings that grip or seat a plain rod, such as rod sockets, table clamps and frames, and they can be moved between set-ups without screwing or unscrewing anything.

Short rods (500 or 600) keep test-tube and titration work compact, while the 1000 to 1500 lengths give room for distillation columns, long condensers and pendulums. Pick 12 or 13 for general teaching work and 16 when several heavy clamps will share one rod. Stainless steel stays smooth and rust-free, so bossheads grip evenly; wipe off spills and avoid bending a rod by overloading its top end.

What to Specify When Ordering

• The diameter, D/Ø 12, 13 or 16, matched to your base, socket or clamp.
• The length from the listed options for that diameter.
• The quantity of each size.
• The base or fitting the rods will be used with, so we can check the fit.

OEM Manufacturer

These rods are made by Jain Scientific Equipments Private Limited, the company that trades as ScienceLab, which is the OEM (original equipment manufacturer) and produces them at its own licensed factory at Saha, Ambala, Haryana, India. Labs topping up their stock, dealers and importers order the exact lengths and diameters they need direct from the factory.

Mixed orders across several sizes are common, so just list what you need and ask us. See the ScienceLab profile for company details.

Stabilizing Ring for Erlenmeyers (Product Code: SLE/LR/15) is a weighted ring used to keep Erlenmeyer (conical) flasks and similar flasks from floating or tipping when they stand in a water bath or other thermal bath. It is listed in three sizes, D/Ø 50, 70 and 100, weighing 207 g, 340 g and 470 g, with a PVC covering over the metal. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India, for research and teaching labs in India.

Specifications

What Is the Stabilizing Ring for Erlenmeyers Used For?

A flask that is only partly full is lighter than the water it displaces, so in a bath it lifts, leans and can tip over, spoiling the sample or letting bath water in. Placing a stabilizing ring on the flask adds enough weight to keep it upright and seated. This is routine when warming culture media, running temperature-controlled reactions, incubating enzyme or microbiology samples, or holding several flasks side by side in one bath.

Match the ring to the flask: the 50 size at 207 g suits small flasks, while the 100 size at 470 g gives the most hold-down force for larger ones. The PVC covering cushions the glass and keeps metal from knocking against it. Fit the ring before the bath is filled or heated, and rinse and dry it after use so no bath water is left trapped under the covering.

What to Specify When Ordering

• The size: D/Ø 50, 70 or 100.
• The flask sizes you will use, so we can suggest the matching ring.
• The number of rings per bath.
• Confirmation of the material you require (PVC-covered steel or stainless).

OEM Manufacturer

Jain Scientific Equipments Private Limited operates as ScienceLab and is the OEM (original equipment manufacturer) of the Stabilizing Ring for Erlenmeyers, produced at its own licensed factory at Saha, Ambala, Haryana, India.

Crucible Retort Ring (Product Code: SLE/LR/16) is a three-point crucible clamp used to hold a crucible securely over a gas flame while substances are heated or ignited in chemistry and materials labs. Its 18/10 stainless steel ring carries three adjustable ceramic Degussit clamping rods, rated to max. 2030 °C, that grip crucibles from 0 to 70 mm, including platinum crucibles. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, a chemistry lab instruments supplier to schools, colleges and research labs.

Specifications

What Is the Crucible Retort Ring Used For?

Heating a crucible strongly, whether to ignite a precipitate in gravimetric analysis, find ash or moisture content, or bring a sample to constant mass, needs a support that holds the crucible steady without shading it from the flame. The three ceramic rods touch the crucible at just three points, so most of its surface is exposed to the heat, and ceramic will not react with or mark a platinum crucible the way bare metal can.

Mounted on a support stand, the ring lets you raise or lower the crucible to set the gap between the gas flame and the crucible bottom; on a tripod it gives a fixed working height. Set the rods by hand to the crucible before lighting the burner, let everything cool before adjusting again, and lift hot crucibles only with tongs.

What to Specify When Ordering

• The crucible sizes you will use, within the 0–70 mm range.
• Whether the ring will be mounted on a support stand or a tripod.
• The number of rings required.
• Whether crucibles or crucible tongs should be quoted as well.

Bossheads 18/10 Stainless Steel (Product Code: SLE/BH/01) is a 90° stainless steel bosshead used to fix clamps, rings and cross rods to the upright rod of a retort stand in school, college and research laboratories. It is listed in thread 6 and thread 8 versions, both with a d/Ø figure of 16,5, and takes a socket screw, heart screw or heart-type safety screw. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer of lab stand hardware, at its own factory in Ambala, India.

Specifications

What Is the Stainless Steel Bosshead Used For?

A bosshead is the joint that turns a plain stand rod into a working support. One bore slides onto the vertical rod of a retort stand and is tightened in place; a clamp shank or horizontal rod goes into the second bore at 90° and is locked with the other screw. In practice this holds burette clamps for titration, condenser and flask clamps for distillation, and rings for funnels or wire gauze. The 18/10 grade (18% chromium, 10% nickel) resists rust and staining on benches where acids, salt solutions and water are handled every day.

Choose the screw style to suit the users. A socket screw needs a hex key and suits setups that should not be adjusted casually, a heart screw is tightened by hand for quick changes, and a safety screw is designed to stay with the bosshead so it is not lost. Tighten both screws firmly before loading glassware, keep the load over the stand base and wipe the bosshead dry after spills.

What to Specify When Ordering

• Thread version: 6 or 8 (both are 18/10 stainless steel with d/Ø 16,5 and a 90° angle).
• Screw type: socket screw, heart screw or heart-type safety screw.
• The diameter of your stand rods, so we can confirm the fit of the d/Ø 16,5 figure (the listing gives no unit).
• Quantity per laboratory or per bench, including a few spares for rearranging apparatus.

Bosshead Malleable Cast Iron Chromium Plated (Product Code: SLE/BH/02) is a chrome-plated 90° bosshead used to join clamps, rings and cross rods to stand rods where a setup carries heavier apparatus or thicker rods. Cast in malleable (tempered) cast iron, it is listed in three sizes, d/Ø 16,5, 20,0 and 36,0, all with thread 8, and takes a heart-type safety screw or a thumb screw. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), the OEM, at its own factory in Ambala, India.

Specifications

What Is the Chrome-Plated Cast Iron Bosshead Used For?

Malleable iron is cast iron that has been heat-treated to make it tougher and less brittle, so a bosshead made from it tolerates repeated tightening and the occasional knock without cracking. The chromium plating protects the iron and gives a bright surface that is easy to wipe. On the bench, the bosshead holds clamps, rings and cross rods at right angles to an upright rod: supporting a separating funnel, fixing a condenser during distillation, or joining rods into a frame for a physics demonstration.

The three d/Ø sizes let you match the bosshead to the rods you already use, with the larger versions intended for thicker rods and heavier frameworks such as those in lab equipment for technical institutes. Fit the thumb screw where users adjust heights often, or the safety screw where the screw should stay with the bosshead. Tighten firmly, test the joint by hand before hanging glassware, and dry the plating after it is splashed.

What to Specify When Ordering

• Size: d/Ø 16,5, 20,0 or 36,0 (all thread 8, 90° angle).
• Screw type: heart-type safety screw or thumb screw.
• The diameter of the rods you use, so we can match the right size (the listing states no unit).
• Quantity for each size, if your laboratory runs rods of different thicknesses.

OEM Manufacturer

Jain Scientific Equipments Private Limited, trading as ScienceLab, is the OEM for this chrome-plated bosshead and makes it at the company's own licensed factory at Saha, Ambala, Haryana, India. It is supplied straight from there to school and college laboratories, technical institutes, distributors and importers in India and international markets, without a trading middleman.

Because all three sizes come from the same maker, a mixed order is quoted and packed together, and repeat supplies or spare screws can be requested from the manufacturer directly. Details about the company are on the profile page.

What is malleable (tempered) cast iron?
It is cast iron that has been heat-treated for toughness, so the Bosshead Malleable Cast Iron Chromium Plated is less likely to crack under repeated tightening than ordinary cast iron, while its chromium plating adds a corrosion-resistant, easy-to-wipe surface.

Which screws are available for this bosshead?
The Bosshead Malleable Cast Iron Chromium Plated is listed with a heart-type safety screw, intended to stay captive in the bosshead, or a thumb screw for quick finger adjustment. Please state your choice when you send an enquiry.

Do all sizes share the same thread and angle?
Yes. All three listed versions of the Bosshead Malleable Cast Iron Chromium Plated, d/Ø 16,5, 20,0 and 36,0, have thread 8 and a fixed 90° angle, so only the size and screw type need to be chosen.

Teachers and lab assistants pick it for student stands because it is easy to carry, and it is listed with d/Ø 16,5, thread 8 and a choice of socket, thumb or heart-type safety screw. Jain Scientific Equipments Pvt Ltd (ScienceLab) makes it as an OEM manufacturer at its own factory in Ambala, India.

Specifications

What Is the Aluminium Bosshead Used For?

Aluminium is much lighter than steel or cast iron, so a tray of these bossheads is easy for students to carry to their benches and a finished stand is less likely to tip. That makes the aluminium bosshead a sensible pick for junior and secondary practicals: holding a thermometer clamp over a beaker, fixing a pendulum support rod, clamping a test tube for heating or attaching a ring for a filter funnel. Aluminium does not rust in ordinary lab conditions, so the fitting stays presentable with little care.

Match the screw style to the class: thumb screws let students change heights quickly, socket screws need a hex key and keep fixed setups from being altered, and the heart-type safety screw is intended to stay with the bosshead instead of going missing. Keep aluminium away from strong alkalis such as sodium hydroxide, which attack the metal, and rinse off any splash straight away. A light bosshead like this is standard physics lab equipment for school practical classes where assemblies are built and taken down within one period.

What to Specify When Ordering

• Screw type: socket screw, thumb screw or heart-type safety screw.
• Your stand-rod diameter, so that the d/Ø 16,5 and thread 8 listing can be confirmed as a fit.
• Quantity per lab or per student station, including spares.
• Any stands, rods or clamps you want quoted together with the bossheads.

Frequently Asked Questions

Why choose the Bosshead Aluminium over a steel or iron bosshead?
The Bosshead Aluminium is lighter than steel or cast iron versions and does not rust in normal lab use, which suits student stands, portable demonstration kits and classes where assemblies are built and dismantled every period.

What are the key dimensions of the Bosshead Aluminium?
The Bosshead Aluminium is catalogued with d/Ø 16,5 (sixteen and a half, written with a decimal comma), thread 8 and a 90° angle. Units for d/Ø are not stated in the listing, so share your rod diameter and ScienceLab will confirm the fit.

Which screw types are available for the Bosshead Aluminium?
The Bosshead Aluminium is listed with three screw options: a socket screw tightened with a hex key, a thumb screw for quick adjustment by hand, and a heart-type safety screw. Name your preferred screw in the enquiry so the quotation matches.

Is the Bosshead Aluminium affected by laboratory chemicals?
Strong alkalis such as sodium hydroxide attack aluminium and some acids can mark it, so rinse and dry the Bosshead Aluminium after any splash. For benches with constant corrosive work, a stainless steel bosshead from the same range is the better option.

Who manufactures the Bosshead Aluminium?
The Bosshead Aluminium is an OEM product of Jain Scientific Equipments Pvt Ltd (ScienceLab), made at the company’s own factory at Saha, Ambala, Haryana, India. Schools, dealers and importers receive it factory-direct, with quotations issued by the manufacturer.

How do I keep the screws of the Bosshead Aluminium working smoothly?
Avoid over-tightening the Bosshead Aluminium, wipe its thread clean from time to time and store the bossheads dry in a tray rather than loose in a drawer, where screws can be knocked, bent or lost.

Can ScienceLab supply the Bosshead Aluminium for a whole class or for export?
Yes. Send code SLE/BH/03 with the screw type, quantity and delivery location; ScienceLab supplies the Bosshead Aluminium to schools and institutions in India and international markets and can quote it together with stands and clamps.
