The Introduction of Pipette

The pipette is a kind of pipettor, which is often used for the removal of small or trace liquid in a laboratory.
Different specifications of pipettes are matched with different size of the heads. The shapes produced by different manufacturers are slightly different, but the working principle and operation method are basically the same.
Pipette is a kind of precise instrument. It should be carefully used and stored to prevent damage and to avoid affecting its measuring range.
Pipette first appeared in 1956. It was invented by Schnitger, a scientist at the German Institute of Physiology and Chemistry. Then, in 1958, the German company began to produce button-type pipette and became the first company in the world to produce pipette. These pipettes can be used in clinical routine chemical laboratories for their liquid absorption ranges from 1 to 1000 ml.
With the development of pipette, it is not only more accurate but also has a variety of types.
There are two kinds of physical principles of the micro-adder:
(1) using air cushion (also known as piston stroke) to add samples;
(2) using non-air cushion piston positive displacement (positive displacement) to add samples.
