A
pipette, comprising a
pipette casing which has disposed therein a seat, a
piston seat in an accommodating body, mounting devices for reversibly fixing the mounting portion and
syringe piston of a
syringe within the seats and
piston adjusting devices for displacing the accommodating body, wherein the mounting portion and
syringe piston are adapted to be slid to their mounting positions through axial apertures, the mounting devices have radially advanceable gripping devices, the gripping devices have syringe gripping levers pivotally supported within the
pipette casing and piston gripping levers pivotally supported within the accommodating body, the syringe gripping levers and piston gripping levers have two arms, the syringe gripping levers, at the insides of their
actuator arms, having contact points which when their
actuator arms are actuated are adapted to be externally pivoted against the
actuator arms of the piston gripping levers, the syringe gripping levers have inwardly projecting release levers on the actuator arms, a transfer element which is slidably guided transversely with respect to the release levers within the pipette casing is adapted to be brought into
abutment against the two release levers by being shifted by a front-end sided
abutment area, and a trigger displaceable within the pipette casing is coupled to the transfer element to displace the transfer element upon displacement of the trigger.
