The pipette is a kind of pipettor, which is often used for the removal of small or trace liquids in a laboratory. Different specifications of pipettes are matched with different sizes of 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 pipettes and became the first company in the world to produce pipettes. These pipettes can be used in clinical routine chemical laboratories for their liquid absorption ranges from 1 to 1000 ml.
The right pipette tip is key for proceeding the accurate and reliable results. Divided into advanced pipette tips, standard pipettes, and advanced filter pipette tips, Hawach pipette tips are designed for multiple applications. With volume ranging from 10ul to 10ml, Hawach pipette tips are flexible and soft tip cone that ensures better sealing without leaking. And you can always get the best recovery of the sample liquid.
Hawach has two different kinds of pipette stands, linear stand and round stand. Both of them can hold up to 6 pipettes. The stand can keep the pipettes away from contamination after use. It also can help you to make your lab neat and in the right order.
With the development of the 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 an air cushion (also known as piston stroke) to add samples; (2) using non-air cushion piston positive displacement (positive displacement) to add samples.
