Pipetting device for metering liquids comprising a piston actuating rod, at least one receiver for a piston head arranged on one end of the piston actuating rod and which is defined by an abutment surface for the piston head in the axial direction of the piston actuating rod, and comprises a through-opening for a piston rod opposing said piston head and a base for supporting the piston head surrounding the through-opening, at least one cylinder with a hollow space, at least one seat for holding a pipette tip, at least one through-channel connecting the hollow space of a cylinder to a through-hole in a seat and at least one piston arranged longitudinally displaceably in a cylinder with a piston rod extending through the through-opening of a receiver and a piston head at the end of the piston rod arranged in the receiver, which is positioned on the base with a lower face facing the piston rod and comprises a resilient body projecting beyond the upper face facing away from the piston rod, which does not bear against the abutment surface in an elastically compressed manner or bears against the abutment surface in a partially elastically compressed manner.
