A pipette, also known as a pipette gun, is a device used to quantitatively transfer liquids. When conducting research in analytical testing, a small or trace amount of liquid is generally removed with a pipette. Pipettes can be divided into gas piston pipettes (Air-displacement pipette) and external piston pipettes (Positive-displacement pipette) according to the principle. Gas piston pipettes are mainly used for standard pipetting, and external piston pipettes are mainly used to handle special liquids such as volatile, corrosive and viscous. Many people ignore the correct use of pipettes and some of the details.
