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 Burets. 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.
