2016-9-1 · Electronic pipettes also possess an immunity so to speak against many issues that plague manual pipettes. More robust seals and O-rings resist wear and tear over a longer course of time while components that fatigue in manual pipettes—the micrometer spring and friction ring for instance—aren t present in electronic pipettes.
Both pipette types have a piston that moves in a cylinder or capillary. In air displacement pipettes a certain volume of air remains between the piston and the liquid. In positive displacement pipetting the piston is in direct contact with the liquid. Complete the form and download a pdf version of the GLP Guide. Download now.

A pipette is a type of chemical dropper used in laboratory experiments to measure and transport fixed volumes of chemicals. There are several designs of pipettes but they all function in the same way. The pipette is inserted into a liquid-filled container where it creates a vacuum. The vacuum suction draws up a designated amount of liquid and
