From Wikipedia, the free encyclopedia
Micropipettes are microtools constructed from glass tubings for microinjection and micromanipulation purposes. Many types and sizes of glass tubing are available, mainly in three different compositions: borosilicate, aluminosilicate and quartz. Each composition has its own unique properties and the right selection is determined by the application it is used for. Micropipettes are mainly used in biological and chemistry experiments. Normal glass pipettes which are used in chemical labs are not highly accurate for volumes less than 1ml, but micropipettes (autopipettes) are both accurate and precise.
