Burette for Bases 25 ml Manufacturer,Supplier and Exporter in India

Burette for Bases 25 ml (Product Code: SCI-115/031) is a 25 ml graduated glass burette with a Teflon or latex valve used to deliver alkaline titrants, such as sodium hydroxide solution, in school and college titration practicals. Chemistry students choose it whenever the titrant would make a ground-glass tap stick, and its scale reads in 0.1 ml divisions, making it a staple of any volumetric analysis kit. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

What Is a Burette for Bases Used For?

A typical use is finding the concentration of an acid by titrating it with standard sodium hydroxide: the alkali goes into the burette, the acid and an indicator such as phenolphthalein go into a conical flask, and the end point is the first permanent pink colour. Alkalis tend to seize ground-glass stopcocks, whereas a Teflon valve resists this and a latex valve has no ground-glass joint at all, so the burette keeps working smoothly.

Mount the burette upright in a burette clamp, rinse it with a little of the alkali before filling and clear any air bubble from the tip. Read the bottom of the meniscus at eye level, and drain and rinse the burette with water soon after the practical, because alkaline solution left standing can etch glass. With a latex valve, check the rubber for cracks before each class.

What to Specify When Ordering

Frequently Asked Questions

What valve does the Burette for Bases 25 ml have?
The Burette for Bases 25 ml is offered with a Teflon or latex valve. Please state which one you want when you ask for a quotation, as both avoid the ground-glass tap that alkaline solutions tend to seize.

Why use a separate burette for bases?
Alkaline solutions such as sodium hydroxide can make a ground-glass stopcock stick fast. The Burette for Bases 25 ml uses a Teflon or latex valve instead, so it keeps delivering smoothly and does not contaminate the acid burette used in the same practical.

What are the capacity and graduation of this base burette?
The Burette for Bases 25 ml holds 25 ml and is graduated in 0.1 ml intervals. It is made of glass described as heat resistant and chemical resistant, with a graduated scale for reading the volume delivered.

How should the Burette for Bases 25 ml be cleaned?
Drain the Burette for Bases 25 ml soon after use, rinse it several times with water, clean the bore with a burette brush if needed and store it upside down. With a latex valve, also check the rubber for cracks or stickiness.
