Pipette Aspiration Rate and Storage

Hawach introduces pipettes from the pipetting speed of the pipette and precautions during storage.

First, the rate of liquid absorption. It is often seen in the laboratory that in order to “improve efficiency”, the user quickly releases the thumb during aspiration, which causes the liquid to quickly rush into the tip.

As everyone knows, this forces the liquid to form a turbulent state after entering the tip, so that for small and medium-range pipettes, a vapor mist that is invisible to the naked eye will enter the inside of the pipette, for a large-scale pipettes.

You will see the liquid flush directly into the inside of the pipette. The end result is contamination or even corrosion of the piston of the pipette, which is prone to cross-contamination of the sample and has an impact on accuracy.
