Burettes

A burette is a long graduated glass tube with a stopcock at its lower end and a capillary tube which is tapered at the outlet of the stopcock. It used to transfer desired volumes of a liquid from one vessel to another. These are generally used in titrations. It is also known as Burette. 

The name Burette was given by Joseph Louis Gay-Lussac, a French Chemist, in the year 1824. 

The first Burette was invented by Etienne Ossian Henry in the year 1845. He was also a French Chemist. An improved version of the Burette was later presented by a German Scientist Karl Friedrich Mohr in the year 1855. 

Automatic Burettes 

Automatic Burettes are those in which the least manpower is required to transfer liquids. This type of burette has a vacuum pump with the help of which one can store the liquid in the burette. Automatic Burettes are also available in Amber Colour too to protect the light-sensitive chemicals.
