How does a pipette work?

A pipette works by creating a vacuum above the liquid-holding chamber and selectively releasing this vacuum to draw up and dispense liquid. Pipettes that dispense between 1 and 1000? l are termed micropipettes, while macropipettes dispense a greater volume of liquid.

How many types of pipettes are there?

The five grades of pipettes include disposable/transfer, graduated/serological, single-channel, multichannel, and repeat pipette.
