Abstract:
A volume adjustable pipette, comprising a plunger mounted for movement in a housing to and from a stop to aspirate a fluid into and dispense the fluid from a tip extending from the housing. The movement of the plunger is damped to reduce sudden plunger movements. An axially moveable volume setting member in the housing defines the stop and a volume setting for the pipette and is axially moveable by a user turnable volume setting member. Turning of the volume adjusting member also controls a coarse volume setting means and a fine volume setting means, the course volume setting means being responsive to a relatively small turning of the volume adjusting member for moving the volume setting member a relatively large axial distance and the fine volume setting means being responsive to a relatively large turning of the volume adjusting member for moving the volume setting member a relatively small axial distance.
