Editing Pipette (section)

==History==
The first simple pipettes were made of glass, such as [[Pasteur pipette]]s. Large pipettes continue to be made of glass; others are made of squeezable plastic for situations where an exact volume is not required.

During or prior to 1877, [[Joseph Lister]] (1827 – 1912) invented the first adjustable micropipette, consisting of a "pipette with a syringe"<ref name="e841"></ref> (photograph shown at right).

The micropipette was patented in 1957 by Dr [[Heinrich Schnitger]] ([[Marburg]], Germany). The founder of the company [[Eppendorf (company)|Eppendorf]], Dr. Heinrich Netheler, inherited the rights and started the commercial production of micropipettes in 1961.

The modern 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]].<ref>{{cite web|url=http://www.biotech.wisc.edu/outreach/pipettestory.html|title=Biotechnology Outreach|access-date=3 March 2016}}</ref><ref>{{cite journal|title=When a common problem meets an ingenious mind |pmc=1369176 |pmid=16138087 |doi=10.1038/sj.embor.7400520 |volume=6 |issue=9 |year=2005 |journal=EMBO Rep. |pages=797–800 |last1=Klingenberg |first1=M}}</ref>
