Zusammenfassung:	A changeable pipette tip includes a first end having a fluid opening and a second end having a pipe elastic in the radial direction having an orifice. The orifice and the fluid opening are in fluid connection. The first end is designed to be coupled to a matching coupling unit of a pipetting unit such that liquid may be sucked into the fluid area through the orifice by an actuating unit in the pipetting unit. In order to eject liquid as free-flying droplets or as a jet from the orifice of the pipe elastic in the radial direction, a volume change of a portion of the pipe elastic in the radial direction is effected.
