A pipette for use with a pipette tip or syringe including a piston positioned within a cylinder comprises a pipette housing extending between an upper end and a lower end. Two parallel rods are positioned in the pipette housing, wherein one of the two parallel rods is coupled to a lifting rod. An operating element is configured to protrude outwardly from the pipette housing and be displaced relative to the pipette housing. A gear mechanism is arranged in the pipette housing and comprises a drive comprising a moveable input member and configured to be driven by the operating element, and an output comprising at least one moveable output member and configured to drive the two parallel rods. Successive displacements of the input member by the operating element are configured to alternately displace one of the two parallel rods and then another of the two parallel rods by the output member.
