Burettes with PTFE Key Stopcock Schellbach Stripe Manufacturer,Supplier and Exporter in India

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.

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.

Do you supply schools in bulk and export orders?
Yes, to institutions and distributors throughout India and international markets.
