Overview
Alfine burettes are made of top quality borosilicate glass. The whole tube consists to the straight tube with graduation scales, stopcock and valve to control the flow of the chemical solution. There are two types: alkali burette and acid burette, which can be made by clear glass or amber glass.

Features
Alkali burette is with a glass bead of latex tube is often used in measuring the volume of non-oxidizing dilute solutions.
Acid burette with glass stopcock or PTFE stopcock is usually used in measuring the volume of a dripped dilute solution which is not strongly alkaline.
Usage
Burette (Volumetric burette, buret) is a volumetric measuring laboratory glassware which is used in analytical chemistry for accurate dispensing of variable, and for measuring the volume of a liquid, especially of one of the reagents in a titration. In a titration of an acid and base solution, the burette can be filled with acid. By turning the tap in a perpendicular direction, the tap can be opened, which then allows the acid in the tube to be able to be added in a stream or drop by drop into a flask.
