General Criteria For Pipette Tips

In 1958, the German company Eppendorf invented the first single-channel fixed-range pipe tte. In 1968, the Finnish Lab system (Raybo) invented a multi-channel fixed-range pipette, which greatly improved the efficiency of pipetting operations. In the early 1970s, Gilson of France introduced the first single-channel adjustable-range pipette and named it Pipetman.

Later, in the late 1970s, Gilson modified it to make the suction/discharge button and the ejection button independent of each other. In the 1980s, Danish CAPP launched a semi-sterilizable, all-metal, high-precision pipette, and Eppendorf launched the Reference series, which can sterilize the entire pipette. In 1984, the United States RAININ (Raining) began to let the world's human body experience the thrill of electric pipettes. In 2000, the Danish cap launched the world's only 64-channel high-precision pipette.

Classification working principle: whether the built-in piston / external piston range is adjustable: adjustable pipette / fixed pipette. Power source: manual pipette / electric pipette. Number of working channels: single-channel pipette / multi channel pipette. special purpose: pipette, continuous dispenser accuracy, and precision accuracy-system error refers to the closeness between the measurement result you get and the real value, expressed as the error.

Generally used to indicate the size of the system error. The degree to which the measured value is close to the true value is called accuracy, and the difference between the two is called error.

Comparative Advantage
It is a common phenomenon in the operation when using the standard tips to remove the surface tension of the liquid, it is easy to leave a film on the inside surface of the tips. The residue of the liquid can lead to the inaccuracy and inconsistency of the fluid transfer results, and also lose some expensive samples. The low-adsorption head was developed to improve the common problem of liquid residue.Half Autoclave Adjustable Pipettes
