Abstract
A pistol-shaped pipetter capable of operation on a full range of pipettes from 0 to 25 ml and which has a pair of vacuum chambers which are activated by trigger-type devices on the pistol grip of the unit. With a small volume pipette the selector valve is placed in one setting wherein only one of the vacuum chambers is directly connected to the pipette. With a larger volume pipette, the selector valve is positioned so as to place both vacuum chambers in communication with it. A rapid discharge of the fluid in the pipette is achieved by trigger actuation while a fine, controlled discharge is achieved by an air bleed valve control.
