The terms 'pipette' and 'pipet' are used interchangeably despite minor historical differences in their usage. Pipettes that dispense between μl are sometimes distinguished as micropipettes. Nomenclature Īlthough specific names exist for each type of pipette, in practice, any type can be referred to as a 'pipette'. The adjustable micropipette is a Wisconsin invention developed through interactions among several people, primarily inventor Warren Gilson and Henry Lardy, a professor of biochemistry at the University of Wisconsin–Madison. Heinrich Netheler, inherited the rights and started the commercial production of micropipettes in 1961. The founder of the company Eppendorf, Dr. The first micropipette was patented in 1957 by Dr Heinrich Schnitger ( Marburg, Germany). Large pipettes continue to be made in glass others are made in squeezable plastic for situations where an exact volume is not required. The first simple pipettes were made in glass, such as Pasteur pipettes. Measurement accuracy varies greatly depending on the instrument.

Many pipette types work by creating a partial vacuum above the liquid-holding chamber and selectively releasing this vacuum to draw up and dispense liquid. Pipettes come in several designs for various purposes with differing levels of accuracy and precision, from single piece glass pipettes to more complex adjustable or electronic pipettes.
