Interfacing of those pipettes utilizing pneumatics allows a number of solutions to be loaded and switched on demand, with solution change instances of 100ms. Glass micropipettes are fabricated in a micropipette puller and are usually utilized in a micromanipulator. A graduated pipette generally utilized in medical technology with serologic pipettes for volumetric analysis. To minimize the possible growth of musculoskeletal problems due to repetitive pipetting, electronic pipettes generally exchange the mechanical model. Irrespective of brand or expense of pipette, every micropipette manufacturer recommends checking the calibration at least every six months, if used regularly.
Those studying forensics and analysis where quite a lot of testing is commonplace will perform monthly calibrations. The micropipette was invented and patented in 1960 by Dr. Heinrich Schnitger in Marburg, Germany. Afterwards, the co-founder of the biotechnology company Eppendorf, Dr. Heinrich Netheler, inherited the rights and initiated the worldwide and general use of micropipettes in labs. In 1972, the adjustable micropipette was invented at the University of Wisconsin-Madison by a number of people, primarily Warren Gilson and Henry Lardy.

Invented by Alar Ainla, currently situated within the Biophysical Technology Lab at Chalmers University of Technology in Sweden. The pipettes are at present produced by Fluicell AB, Sweden. A current introduction into the micropipette field integrates the flexibility of microfluidics into a freely positionable pipette platform. At the tip of the device a localized circulate zone is created, allowing for fixed management of the nanoliter environment, directly in entrance of the pipette. The pipettes are produced from polydimethylsiloxane (PDMS) which is shaped using reactive injection molding.
Companies in the drug or meals industries are required to calibrate their pipettes quarterly (every three months). Schools which are conducting chemistry courses can have this process annually.
