A pipette, also known as a pipette gun, is a measuring tool that transfers liquid from the original container to another container within a certain range. It is widely used in biology, chemistry, and other fields.
The basic structure
Hawach pipette is widely used in the clinical laboratory because of its simple structure and easy to use. Its basic structure mainly has the display window, the capacity adjustment part, the piston, the 0- shape ring, the suction tube and the suction head (suction nozzle) and so on several parts.

The working principle of
The design basis of the micropipette commonly used in the clinic is Hooke’s law: that is, the long force of spring extension is proportional to the elasticity within a certain limit, that is, the volume of liquid in the pipette is proportional to the spring elasticity in the pipette.
There are two physical principles of micropipette loading: the use of air pad loading and the use of positive displacement with no air pad. The micropipette of these two different principles has different specific applications.

Common classification
According to the working principle, it can be divided into air displacement pipette and forward displacement pipette.
It can be divided into the single-channel pipette and multi-channel pipette according to the number of pipettes that can be installed simultaneously.
