ABSTRACT:
There is disclosed a pipette and a method of using the pipette in which an active element of the pressurizing system is a bellows within a piston chamber, operated by a motor. To achieve the advantages of the invention, including ease in manufacturing and the ability to actuate a tip ejector, the bellows is mounted so that the outside surface of the sidewall of the bellows, together with the piston chamber, defines the air volume operative on a fluid passageway leading to a disposable tip.
