Burette Class B With Glass Stopcock
Product Code : LSK-GB-10415
Burette Class B With Glass Stopcock (SKU LSK-GB-10415) is a graduated borosilicate glass tube with a glass stopcock at its lower end, used to deliver measured volumes of solution during titrations. Students meet it in school volumetric analysis practicals, and it stays in daily use in college, pharmacy and technician training laboratories. Science Lab Supplies supplies it from Ambala, India to schools, colleges, training institutes, tender contractors and distributors.
Specifications
The burette body is borosilicate glass, and its graduations are printed in amber colour so they stand out against clear solutions. Flow is controlled by a glass stopcock, and the Class B marking places it in the general-purpose tolerance class that teaching laboratories and routine titration work commonly use.

Applications and Experiments for the Burette Class B With Glass Stopcock
This burette is used wherever a solution must be added drop by drop and its volume read accurately, most often in acid–base, redox and precipitation titrations. It is standard titration apparatus for Class 11–12 chemistry practicals, B.Sc. volumetric analysis, pharmacy analysis labs and laboratory technician training.
- CBSE/NCERT Class 11 chemistry: standardising sodium hydroxide against oxalic acid.
- Class 12 chemistry: redox titrations of potassium permanganate against oxalic acid or Mohr's salt.
- B.Sc. chemistry: volumetric analysis, including complexometric and precipitation titrations.
- D.Pharm and B.Pharm pharmaceutical analysis: titrimetric assays.
Standard Scope of Supply
The Burette Class B With Glass Stopcock is supplied as a single unit as described above, with its glass stopcock; any optional accessories are listed on the quotation. A burette stand, clamp and titration flasks are separate items and can be added to the same enquiry.

Frequently Asked Questions
What does Class B mean on this burette?
Class B is the general-purpose tolerance class for volumetric glassware. It allows a wider tolerance than Class A, so it suits student titrations and routine work where the tightest volumetric accuracy is not needed.
How should the glass stopcock be looked after?
Keep a thin film of stopcock grease on the glass key and rinse the burette after use. Do not leave strong alkaline solutions standing in it, because they can make a glass key seize.
Who supplies the Burette Class B With Glass Stopcock?
It is supplied by Science Lab Supplies from Ambala, India. Schools, colleges, contractors and distributors receive item-wise quotations, and the burette can share one order with stands, clamps and other glassware.
Can burettes be quoted in bulk for a school or tender?
Yes. Send the number of burettes, the delivery location and any tender specification, and the quotation is prepared item by item for that quantity.
