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 Teflon 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, which makes it a standard item for titration work in schools and colleges. Science Lab Supplies provides it from Ambala, India to institutions, tender contractors and resellers.

Specifications

This model holds 50 ml and carries graduations down to 0.1 ml along its glass tube. The lower end is closed by a Teflon or latex tap fitted with a valve, so an alkaline solution can be run out drop by drop. The glass is listed as 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 and is common practice in school chemistry lab equipment in India.

• CBSE Class 11 chemistry: titrating sodium hydroxide against a standard acid such as oxalic acid.
• 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.

Standard Scope of Supply

The Burette for Bases is supplied as one 50 ml glass burette with its Teflon or latex tap and valve in place, as described above; any optional accessories are listed on the quotation. Stands, clamps, funnels and indicator solutions are separate items that can be added to the order.

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. Requests can be sent via the contact page or built up in the enquiry cart; institutional buyers will find tender details 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 Teflon 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 Teflon or latex tap with a valve for alkaline solutions.

Who supplies the Burette for Bases?
Science Lab Supplies handles the supply from Ambala, India, quoting schools, colleges, dealers and tender contractors directly for single pieces or class quantities.

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.

Related Titration Equipment

Many laboratories keep an acid burette and a base burette side by side on one burette stand. The four items below cover that pairing, the clamp that holds both tubes, the funnel used for filling and the flask that receives the titrant, all from the Chemistry Lab range.

• Burette for Acids — 50 ml burette with a glass stopcock for acidic titrants.
• Double Burette Clamp Fisher — holds two burettes on one stand.
• Glass Funnel — 75 mm short-tail funnel for filling the burette.
• Conical Pot (Erlenmeyer) 100ml — conical flask for the acid sample.
