This technique requires the telescopic motion of a spring, facilitating the piston’s suction and discharge of liquids. When the piston is pushed, a part of air is expelled, making a partial vacuum that pulls in the liquid resulting from atmospheric pressure.

good displacement method: Repeated pipettes or specialized optimistic displacement pipettes often make use of the optimistic displacement theory. immediate contact with the liquid is produced by a disposable piston that moves Within the suggestion.

for almost any radioactive contamination, clean the micropipette with an answer like Decon after which air dry.

The technological know-how and procedure guiding a multichannel pipette is comparable to that of an individual channel, except it will require multiple suggestion at any given time.
