Glassware Burettes

Burettes (Product Code: SLE/GBu/01) are Class A graduated glass tubes with a PTFE key stopcock, used to deliver a measured, variable volume of titrant during volumetric analysis. They are made from heavy-duty borosilicate glass with blue graduations and are offered in 5, 10, 50 and 100 ml capacities for chemistry laboratories in schools, colleges and industry. Manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, a burette is the central piece of any titration kit for schools in India.

Specifications

Typical Use

Acid–base titrations such as hydrochloric acid against sodium hydroxide, redox titrations with potassium permanganate and complexometric titrations with EDTA all rely on a burette to measure exactly how much titrant has been added to reach the end point. The 50 ml size covers most student and routine titrations; 5 ml and 10 ml burettes are chosen when only small volumes of titrant are expected, and the 100 ml size suits titrations with a large titre. Blue graduations stand out clearly against most solutions, making the meniscus easier to read.

Rinse the burette with a little of the titrant before filling, clamp it vertically on a burette stand, and run a few millilitres through the tip to clear any air bubble. Read the bottom of the meniscus at eye level, and add titrant drop by drop near the end point while swirling the flask. The PTFE key needs no grease and resists sticking, which keeps the stopcock smooth even with alkaline titrants; loosen the key slightly when the burette is stored.

Micro Burettes, Class-A (Product Code: SLE/GBu/02) are small-capacity burettes designed for precise analytical methods in micro chemistry, made in 5 ml and 10 ml sizes. Precision bore tubing assures accuracy between any two points along the body, the tapered tip gives a smooth, controlled flow, and a funnel top allows reagent to be poured in or drawn up from below through a rubber-stoppered tube. Manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, they are a precise addition to a volumetric analysis kit in India’s college, research and quality-control laboratories.

Specifications

Typical Use

Micro-scale titrations use a fraction of the reagent and sample needed for a conventional titration, which matters when a standard solution is costly, hazardous or available only in small amounts, or when the sample itself is limited. Analysts use micro burettes for small-volume determinations in research and quality control, and teachers use them to run microscale chemistry practicals that cut chemical consumption and waste. Because the bore is uniform, a reading taken between any two graduations can be relied on, not only readings from the zero mark.

For volatile or unpleasant reagents, filling from below through a rubber-stoppered tube keeps the liquid enclosed; for routine solutions, simply pour into the funnel top. Secure the burette in a burette clamp so it hangs truly vertical, fill slowly to avoid trapping air, and check that the tapered tip is free of bubbles before the first reading. With such small volumes, a single drop is a significant fraction of the titre, so approach the end point slowly and read the meniscus at eye level.

The Burette, Class-B, with Glass Key (Product Code: SLE/GBu/03) is a heavy-duty borosilicate glass burette fitted with a glass stopcock key and marked with blue graduations, intended for routine titrations in teaching and general-purpose chemical laboratories. It is produced in 10, 25, 50 and 100 ml capacities by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, and is a practical choice when stocking chemistry lab equipment for schools in India where Class B accuracy meets the requirement.

Specifications

Typical Use

Secondary-school and undergraduate practicals — standardising an acid, finding the concentration of an alkali or estimating iron with permanganate — are well served by a Class B burette, whose tolerance is wider than Class A but entirely adequate for teaching. The 25 ml and 50 ml sizes are the usual choices for student benches, the 10 ml size suits small titres, and the 100 ml size is useful where a large volume of titrant is delivered. When equipping a school laboratory setup in India, many institutions use Class B burettes for student practicals and keep Class A burettes for staff and project work.

A glass key needs a thin film of stopcock grease to turn smoothly and seal; apply it sparingly to the key, away from the bore hole, so grease does not block the tip. Do not leave alkaline solutions standing in the burette, as they can cause a glass key to seize; drain and rinse promptly after use. For storage, remove the key or slip a strip of paper between key and barrel so that the two cannot stick together.

Frequently Asked Questions

Which capacities can I order?
10 ml, 25 ml, 50 ml and 100 ml.

What is the difference between Class B and Class A?
Class B burettes have a wider permitted tolerance than Class A. They suit teaching and routine work; for precise analysis, choose a Class A burette.

Does the glass key need grease?
Yes, a thin film of stopcock grease keeps it turning smoothly and prevents leaks. If you prefer a grease-free stopcock, see the Class B burette with PTFE key.

Can I use it for sodium hydroxide titrations?
Yes, but drain and rinse the burette promptly afterwards; alkali left in contact with a glass key can make it stick.

Burette, Class-B, with PTFE Key Stopcock (Product Code: SLE/GBu/04) is a graduated burette for delivering measured volumes of titrant, drawn in heavy-duty borosilicate glass and fitted with a PTFE key stopcock. It is intended for routine volumetric work in school, college and teaching laboratories, where Class B accuracy suits student titrations and practical examinations. The burette is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, as part of its borosilicate laboratory glassware in India and international markets.

Specifications

Typical Use

In an acid–base titration the burette is clamped upright on a stand, rinsed with a little of the titrant, filled above the zero line and then run into a conical flask until the indicator changes colour. The volume used is simply the final reading minus the initial reading, both taken at eye level against the bottom of the meniscus. Before the first reading, open the stopcock briefly to push any trapped air out of the jet, as a bubble there is a common cause of error in student results.

A PTFE key is normally used without stopcock grease, so there is no lubricant to smear the bore or find its way into the solution — a practical advantage for chemistry lab equipment in schools in India, where the same burettes pass through many hands each week. The 25 ml and 50 ml sizes cover most school titrations, while the 5 ml and 10 ml sizes help when reagents are costly or only small volumes are available.

Manufacturer

This Class B burette is manufactured by Jain Scientific Equipments Private Limited, the company that trades as ScienceLab from Ambala, Haryana, India. The firm produces glassware and teaching apparatus for chemistry, physics and biology laboratories and supplies them to institutions and distributors. You can read about its background and product groups on the company profile page.

Frequently Asked Questions

Which capacities can I order?
Five sizes are listed: 5 ml, 10 ml, 25 ml, 50 ml and 100 ml. Mention the size and number required for each in your enquiry.

What does Class B mean for this burette?
Class B is the general-purpose accuracy grade, with a wider permitted tolerance than Class A, which makes it well matched to teaching and routine work. For the tolerance figure of a particular size, please contact us.

Does the PTFE key need greasing?
Normally not. Keep the key and barrel clean, rinse after use and avoid over-tightening the retaining fitting so the key turns smoothly.

Can the burette be dried in a hot oven?
The borosilicate glass is heat resistant, but graduated volumetric glassware is usually left to drain and air-dry rather than being heated strongly, to protect the accuracy of the scale.

Is a calibration certificate available?

Burettes Detachable Stopcock (Product Code: SLE/GBu/05) are graduated borosilicate glass burettes whose PTFE key stopcock can be taken off the body, so the barrel, jet and key can be washed and dried separately. They suit teaching laboratories, college chemistry departments and quality-control benches that run titrations daily and want glassware that is easy to strip down and look after. The burettes are produced by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, for buyers of school chemistry lab equipment in India and abroad.

Specifications

Typical Use

These burettes are used for volumetric analysis in the usual way — mounted vertically, filled with standard solution and read before and after delivery — but their real benefit shows at the end of the session. Coloured or reactive titrants can leave deposits in the stopcock bore, and with a fixed stopcock that area is hard to reach. Detaching the stopcock lets a technician clean the barrel with a brush, soak the key and jet separately, and let every part drain fully before storage.

When reassembling, seat the key squarely, fill the burette with water and leave it closed for a short time to confirm there is no drip at the jet before issuing it to students. Storing the stopcock loosened or removed during long breaks also helps prevent the key from sticking.

Manufacturer

ScienceLab is the brand name of Jain Scientific Equipments Private Limited, a company based in Ambala, Haryana, that makes laboratory glassware and teaching apparatus. The company is incorporated under CIN U29309HR2020PTC087597 and manufactures at its licensed factory at 449, HSIIDC Industrial Area, Saha, Ambala (Factory Licence AMB-ONLINE-CHD-J-414). More about the business is on our company profile.

• Burette Stand, Hard Wood, Double — holds two burettes side by side, for example titrant and blank
• Burette Brush — reaches the full length of the barrel once the stopcock is removed
• Methyl Red (Indicator) — an indicator used in acid–base titrations

Compare other stopcock styles in the Glassware Burettes range.

Frequently Asked Questions

Why choose a detachable stopcock?
It can be removed from the burette, so the stopcock and bore are easier to clean, inspect and dry than on a fixed design.

What is the stopcock key made of?
PTFE. The body of the burette is heavy-duty borosilicate glass.

How do I check for leaks after refitting the stopcock?
Fill with water, close the key, clamp the burette upright and watch the jet for a few minutes. If it drips, reseat the key and test again before use.

Burettes with PTFE Needle Valve Stopcock (Product Code: SLE/GBu/06) combine a graduated borosilicate glass body with a Rotaflow-type PTFE needle valve in place of a conventional key. The valve gives a leakproof seal and finer control of flow, needs no lubrication and avoids the plug seizure that can affect ground stopcocks. They are chosen by college, university and analytical laboratories that want precise, drop-by-drop delivery near the end point, and are made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, for chemistry lab glassware buyers in India and overseas.

Specifications

Typical Use

A needle valve opens progressively as it is turned, rather than in a single quarter-turn, so the operator can run titrant quickly at first and then slow it to single drops or even part-drops as the colour change approaches. That makes this burette well suited to titrations with gradual or subtle end points, to repeat determinations where readings must agree closely, and to teaching students careful end-point technique.

Open and close the valve with light finger pressure only; the seal comes from the PTFE needle seating in the glass, and forcing it closed does not improve the seal. Because no grease is used, the burette is simple to rinse and there is no lubricant to contaminate sensitive solutions. For stable readings, clamp it on a burette stand — a standard piece of chemistry lab equipment in India — with the jet just inside the neck of the receiving flask.

Manufacturer

These needle valve burettes come from Jain Scientific Equipments Private Limited, which markets its laboratory products under the ScienceLab name. The company works from Ambala in Haryana, India, and serves teaching and analytical laboratories at home and abroad. Visit the company profile for an overview of the organisation.

Related Laboratory Equipment

Pair this burette with the following for a complete titration set-up:

• Burette Stand with Clamp & Bosshead — stand, clamp and boss head for mounting the burette
• Flask, Conical, Wide Neck — a receiving flask with room for the jet and a wash-down
• Wash Bottle LDPE with Narrow Mouth — for rinsing a hanging part-drop into the flask
• Burette, Class-B, with PTFE Key Stopcock — a quarter-turn key alternative for routine class work

Other burette designs are listed under Glassware Burettes.

Frequently Asked Questions

How does a needle valve differ from a key stopcock?
A key opens with a quarter-turn, while a needle valve opens gradually as it is rotated, giving much finer control of flow near the end point.

Does the valve need stopcock grease?
No. The PTFE needle valve eliminates the need for lubrication, so there is no grease to wipe away or contaminate the titrant.

Will the valve stick if the burette is stored for a while?
The PTFE needle design is intended to avoid plug seizure. Rinse and drain the burette before storage and leave the valve lightly closed.

What accuracy class is this burette?
An accuracy class is not stated in our listing for this model. Please contact us if your method specifies one.

Burettes with PTFE Key Stopcock Schellbach Stripe (Product Code: SLE/GBu/07) pair a Schellbach-striped scale, which makes the meniscus easier to read, with a PTFE key stopcock that turns smoothly without grease. Made from high-quality, heavy-duty borosilicate glass and graduated along the tube, they are a good fit for practical examinations and busy student benches where quick, consistent readings matter. Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, manufactures them alongside its wider borosilicate glassware in India and for international markets.

Specifications

Typical Use

A Schellbach stripe is typically a narrow coloured line on a white band running down the back of the burette. Seen through a clear liquid, the meniscus bends the stripe so that it appears to pinch to a point exactly at the liquid level, which gives a sharper reference than judging the curve of the meniscus alone. Students make fewer parallax errors, and a teacher checking readings across a room of benches can verify them quickly.

The burette is used in the familiar sequence of rinse, fill, clear the jet, take an initial reading and titrate to the end point, and it is a natural choice when assembling a chemistry titration kit for school acid–base practicals. Read the level where the stripe narrows to a point, and keep the burette vertical on its stand so the stripe stays directly behind the scale.

Manufacturer

Jain Scientific Equipments Private Limited operates under the ScienceLab brand from Ambala, Haryana, making glassware and apparatus for school, college and research laboratories. Buyers who want to know more about the company before ordering can see our company profile.

Related Laboratory Equipment

Other items used with this burette at the titration bench:

• Burette Clamp, Die Cast – Single Clamp — keeps the burette vertical so the stripe reads true
• Retort Stand — the stand rod and base to carry the clamp
• Conical Flask — the receiving vessel for the titration
• Burettes with Schellbach Stripe — the striped version with a glass key stopcock
• Burettes with detachable Stopcocks Schellbach Stripe — striped scale with a removable stopcock

The complete line-up is in our Glassware Burettes category.

Frequently Asked Questions

What does the Schellbach stripe do?
It gives a sharp visual marker at the meniscus, so the liquid level can be read more consistently and with less parallax error.

Is the stopcock glass or PTFE?
This model has a PTFE key. If you prefer a glass key with a Schellbach stripe, see Burettes with Schellbach Stripe in the list above.

Does the stripe help with dark or coloured solutions?
The effect is clearest with colourless liquids. With strongly coloured titrants the meniscus may need to be read at its top edge instead; follow the method your syllabus specifies.

What sizes are offered?
5 ml, 10 ml, 25 ml, 50 ml and 100 ml graduated burettes.

Can I get a calibration certificate?
Please raise any calibration documentation needs with us via the contact page so we can advise before you order.

How should the burette be cleaned?
Rinse with water straight after use, brush the barrel if residues remain, rinse with distilled water and let it drain upside down with the stopcock open.

Burettes with detachable Stopcocks Schellbach Stripe (Product Code: SLE/GBu/08) bring together two practical features in one graduated burette: a Schellbach stripe for accurate meniscus reading and a PTFE key stopcock that can be removed for cleaning. The body is high-quality, heavy-duty borosilicate glass. This combination suits shared teaching laboratories where readings need to be reliable and the glassware must also be easy for technicians to service. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, a laboratory glassware manufacturer serving India and international markets.

Specifications

Typical Use

During a practical, the stripe helps every student read the level the same way: the stripe appears to narrow to a point at the meniscus, and that point is taken as the reading. After the class, the stopcock is detached so the barrel can be brushed through end to end and the key rinsed on its own, which keeps the bore free of dried reagent and the stripe clearly visible for the next group.

When planning a school laboratory setup in India or elsewhere, departments often standardise on one burette pattern for all benches. This model is a sensible choice where both reading consistency and ease of maintenance are priorities. Check each reassembled burette with water for leaks before use, and store it with the stopcock removed or loosened.

Manufacturer

The manufacturer is Jain Scientific Equipments Private Limited, better known by its trading name ScienceLab. From Ambala in Haryana, the company supplies glassware, instruments and teaching aids to laboratories in India and abroad. Learn more on our company profile.

Burettes with Schellbach Stripe (Product Code: SLE/GBu/09) are graduated, heavy-duty borosilicate glass burettes fitted with a traditional glass key stopcock and a Schellbach stripe for accurate meniscus reading. With glass for both the body and the key, they appeal to laboratories that prefer a conventional all-glass burette while still wanting the clearer reading the stripe provides. They are manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, among its chemistry lab glassware for customers in India and international markets.

Specifications

Typical Use

This burette is used for standard volumetric titrations — neutralisation, precipitation and redox methods — in school and college chemistry. Used with an acid base indicator kit, it lets students follow the colour change while the stripe gives a crisp reference point at the meniscus for each reading. Fill it with the help of a small funnel, then remove the funnel before titrating so drops from its stem do not alter the level.

A glass key needs a little care. Apply only a very thin film of stopcock grease to the key, keeping it clear of the bore, and wipe off any excess. After use, rinse the burette and, before storage, remove the key or place a thin strip of paper between key and barrel so the ground surfaces cannot stick together.

Manufacturer

ScienceLab burettes are made by Jain Scientific Equipments Private Limited, headquartered in Ambala, Haryana, India. Trading as ScienceLab, the company produces a broad catalogue of laboratory glassware and apparatus for education and research. Full company information is on the company profile page.

Burette Brush (Product Code: SLE/GBu/10) is a long cleaning brush for the narrow barrel of a burette, measuring 24" overall with an 8.5" section of white nylon bristles and a 0.50" brush diameter. Its double thick gauge, wire-wound handle is heavy-duty yet flexible, so it can be pushed down a full-length burette tube. Laboratory technicians and students use it to clear reagent films and residues after titrations. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, a lab consumables supplier in India and international markets.

Specifications

Typical Use

After a titration session, rinse the burette with tap water, wet the brush in a mild laboratory detergent solution and work it down the barrel from the top with a gentle twisting motion, then draw it back. The long handle reaches the lower graduations without the hand entering the tube, and the flexible wire lets the brush follow the tube rather than jamming. Finish with tap water and a final rinse of distilled water, and let the burette drain inverted.

Do not force the brush into the narrow jet below the stopcock; clean that part by flushing instead. Keep the twisted wire tip away from hard contact with the glass, rinse the brush after each use and hang it to dry. When bristles begin to splay or wear, replace the brush — a routine item for any chemistry consumables supplier in India to stock alongside other glassware cleaning tools.

Supplier

This brush is supplied by Jain Scientific Equipments Private Limited, which trades as ScienceLab from Ambala, Haryana, India, and supports laboratories with glassware, apparatus and cleaning accessories. For vendor registration forms, the company's GSTIN is 06AAECJ8618A1ZT and its LEI is 3358004HRD1JIVXKYX49. Read more on our company profile.

Burette Clamp, Die Cast – Single Clamp (Product Code: SLE/GBu/12) is a die-cast retort clamp with a built-in boss head and a single burette clamp, used to hold one burette upright on a stand rod during titration. Spring-loaded jaws with rubber grips close on the burette quickly and hold it steadily, and the metal surfaces have a high-quality finish. It is supplied as a pack of 10 and manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, as part of the chemistry lab equipment it makes in India for schools, colleges and overseas buyers.

Specifications

Typical Use

Slide the built-in boss head onto the rod of a retort stand and tighten it at a height that leaves the burette jet just inside the neck of the titration flask. Press the spring-loaded jaws open, place the burette between them and release; the rubber grips close around the glass so it stays upright without over-tightening. Because the boss head is part of the casting, there is no separate boss to lose, and the burette can be taken out and replaced in seconds when students refill or change solutions.

Check by eye that the burette hangs vertically before taking readings, and wipe the rubber grips clean if reagent is spilled on them. Supplied in packs of 10, the clamp is convenient for school lab equipment bulk supply, letting a department equip a full row of titration benches with matching fittings.
