Burette for Bases

Product Code : SCL-CL-11693
Burette for Bases (SKU SCL-CL-11693) is a 50 ml graduated glass burette whose outlet is controlled by a PTFE or latex tap with a valve instead of a ground-glass stopcock. That design lets alkaline titrants such as sodium hydroxide be dispensed without the tap seizing, and it suits titration work in schools and colleges. Orders for it are handled by Science Lab Supplies in Ambala, India, whether the buyer is a school, a college department, a reseller or a tender contractor.
Specifications
The table lists every specification of this alkali burette. In short, the 50 ml glass tube is graduated down to 0.1 ml and closed at the lower end by a PTFE or latex tap fitted with a valve, so an alkaline solution can be run out drop by drop; the glass is heat resistant and chemical resistant.

Applications and Experiments for the Burette for Bases
The base burette delivers measured volumes of alkali into a flask until an indicator changes colour, so students can calculate the strength of an acid or check a standard solution. Keeping a separate burette for alkaline titrants avoids stuck glass taps, which makes it useful school chemistry lab equipment in India for regular titration practicals.
- CBSE Class 11 chemistry: titrating sodium hydroxide against a standard acid such as oxalic acid held in a Conical Pot (Erlenmeyer) 100ml.
- Class 10 science: neutralisation between an acid and a base shown with an indicator.
- B.Sc. chemistry: alkalimetry and the preparation and checking of standard alkali solutions.
- Bench routine: fill the tube through a Glass Funnel and rinse it afterwards from a Plastic Washing Bottle (Pisetta).
Standard Scope of Supply
The Burette for Bases is supplied as one 50 ml graduated glass burette with its PTFE or latex tap and valve in place, as described above; any optional accessories are listed on the quotation. Stands, clamps, funnels and indicator solutions can be added to the same order on request.
Packing, MOQ and Lead Time
You can ask for a single burette or a batch large enough for a full practical class. The quotation you receive sets out packing, delivery time and price for that exact number, and it can also include a burette stand, clamps and flasks for the same titration bench.
Science Lab Supplies holds an Importer-Exporter Code as a registered exporter and is able to ship to buyers in Bangladesh, Zambia, Rwanda, South Africa, Qatar and Sri Lanka. Send your burette count and delivery town through the contact page, build a combined list in the enquiry cart, or read the bid terms on the lab tender page.
Frequently Asked Questions
Why use a separate burette for bases?
Strong alkalis such as sodium hydroxide can make a ground-glass stopcock stick. A PTFE or latex tap with a valve avoids that problem, so the burette keeps working smoothly after repeated alkali titrations.
How is it different from the Burette for Acids?
Both hold 50 ml and read to 0.1 ml. The acid version uses a glass stopcock suited to acids and oxidising titrants, while this one has a PTFE or latex tap with a valve for alkaline solutions.
Who supplies the Burette for Bases?
Quotations for this burette are prepared by Science Lab Supplies in Ambala, India. Schools, colleges, dealers and tender contractors can each ask for a single piece or a class quantity, and the same document can carry the matching acid burette.
How should the burette be cleaned after use?
Run distilled water through the tube and tap straight after the titration, drain it fully and store it upside down or in a rack so that no alkali dries inside the tap.
