Burettes Class B
Product Code : LSK-GB-10414
Burettes Class B (SKU LSK-GB-10414) are borosilicate glass burettes with an amber printed scale and a PTFE needle valve stopcock that lets the titrant be released in a fine, steady stream or single drops. They are aimed at school, college and training laboratories that need dependable general-purpose burettes for daily titrations. Supply is handled by Science Lab Supplies from Ambala, India, for schools, colleges, institutes, tender contractors and distributors.
Specifications
Each burette tube is borosilicate glass with its graduations printed in amber colour. Flow is set by a PTFE needle valve rather than a plug, so small turns give fine control near the end point and no grease is needed. The Class B rating marks general-purpose tolerance; capacity is confirmed on the quotation.

Applications and Experiments for the Class B Burettes
With a needle valve, students can slow the flow to a drop at a time without the jerky start a plug stopcock sometimes gives. That makes these Class B burettes well suited to learners doing their first end-point titrations, and to technicians who run many routine titrations a day.
- CBSE/NCERT Class 11–12 chemistry: acid-base and permanganate titrations in volumetric analysis.
- B.Sc. chemistry: acid-base, redox and precipitation titrations.
- D.Pharm and B.Pharm pharmaceutical analysis: titrimetric assays.
- Water and food testing: routine titrations such as hardness and acidity checks.
Standard Scope of Supply

Frequently Asked Questions
What is a needle valve stopcock?
It is a tapered PTFE valve opened by turning, so the gap widens gradually. This gives smooth, fine control of flow down to single drops, and it needs no grease.
Are these burettes suitable for school use?
Yes. Class B is the general-purpose tolerance class used in teaching labs, and the amber scale and grease-free valve make the burettes easy for students to read and handle.
Which capacity can I order?
The listing does not specify capacity. Tell us the volume you need through the contact page and the quotation will confirm it.
Who supplies the Burettes Class B?
Science Lab Supplies supplies them from Ambala, Haryana, India, and replies directly to schools, colleges, laboratories and distributors with item-wise quotations.
