Product Code : SCL-LG-12006
Borosilicate Glass Burette 50ml (SKU SCL-LG-12006) is a Class A titration burette with 0.1 ml subdivisions and a straight-bore PTFE stopcock plug that turns without grease. It suits accurate titrant delivery in acid-base and redox work, from senior school chemistry to university and quality-control laboratories. Colleges, schools, laboratories, tender contractors and distributors can request it from Science Lab Supplies, which works out of Ambala, India.
Specifications
The 50 ml burette's full specification is tabulated below. In short, it has a heavy-walled borosilicate 3.3 barrel with a uniform bore and enamel graduations fused onto the glass; a handle on the PTFE plug opens the straight bore, a locking nut holds the plug in place, and the tip is shaped for even drops.

Applications and Experiments for the 50 ml Glass Burette
In volumetric analysis the titrant runs from the burette into a conical flask until the indicator changes, and the volume used is read from the scale. Class A tolerance and 0.1 ml divisions suit graded practicals and routine analytical work, with the burette held on a Laboratory Retort Stand.
- CBSE/NCERT Class 11–12 chemistry: titrations of oxalic acid and Mohr's salt against potassium permanganate.
- B.Sc. chemistry: acid-base, redox and precipitation titrations.
- Pharmacy and food-technology labs: standardising solutions and assay titrations.
- Quality-control laboratories: routine titrimetric testing of materials.
Standard Scope of Supply
Each set holds two 50 ml borosilicate burette barrels, two interchangeable straight-bore PTFE stopcock plugs and an operation guide. A burette stand, clamp, filling funnel such as the Borosilicate Filter Funnel, and titrant can be quoted alongside.
Packing, MOQ and Lead Time
Quotes are available for a single set or for the number of sets needed to equip a full titration class. You will receive packing, delivery time and price for your quantity in writing, and clamps, funnels and conical flasks can be combined with the burettes.
Registered as an exporter with an Importer-Exporter Code, Science Lab Supplies can ship to buyers in Sri Lanka, Vietnam, Malaysia, Peru, Egypt and Iraq. The number of burette sets needed can be sent on the contact page, kept with other titration items in the enquiry cart, or matched to a bid through the lab tender page.
Frequently Asked Questions
Does the PTFE stopcock need grease?
No. The straight-bore PTFE plug turns smoothly without grease, so the titrant is not contaminated. If the handle resists, do not force it; adjust the locking nut instead.
How is this burette filled and zeroed?
Clamp it vertically, close the tap, fill through a small funnel to just above zero, run a little liquid into a waste beaker to clear air from the tip, then set the meniscus on the zero line at eye level.
How should it be stored?
Rinse the bore with distilled water after each titration, remove the PTFE plug for long storage so it does not deform, and keep the dried burette upright or inverted in a rack.
Who supplies the Borosilicate Glass Burette 50ml?
Schools, colleges, laboratories and distributors can buy these burette sets from Science Lab Supplies, an Ambala, Haryana, India business that handles each enquiry and quotation directly.
