Applications and Experiments for the Burette Class B With Glass Stopcock
This burette adds a solution drop by drop while the delivered volume is read from its scale, which makes it suitable for acid–base, redox and precipitation titrations. It fits Class 11–12 chemistry practicals, B.Sc. volumetric analysis, pharmacy analysis labs and laboratory technician training as part of a titration apparatus set.
- CBSE/NCERT Class 11 chemistry: standardising sodium hydroxide against oxalic acid, with the titrand held in a Conical Flask.
- Class 12 chemistry: redox titrations of potassium permanganate against oxalic acid or Mohr's salt.
- B.Sc. chemistry: complexometric and precipitation titrations, with 5 ml aliquots measured in Graduated Pipettes and drawn up with a Pipette Filler Bulb.
- D.Pharm and B.Pharm pharmaceutical analysis: titrimetric assays.

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?
Science Lab Supplies in Ambala, India handles the supply of this burette and prepares item-wise quotations for schools, colleges, contractors and distributors; it can travel in one consignment with stands, clamps and other glassware from the same range.
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 Science Lab Supplies prepares an item-by-item quotation for that quantity, which can also list flasks, pipettes and stands.
