The invention relates to a pipette, comprising a tip remover element (6.1) which, upon moving it against a tip, disengages the tip. The remover element is operated with a mechanism, comprising a rotatable ramp member (15.1) which is provided with a circle-forming ramp surface, including one or more segments within which the ramp surface has a high point and a low point, whereby the ramp surface, upon rotating through a single segment, forces the remover element (6.1) first to move against the tip and then allows it to return.
