Abstract
The present invention relates to a coupling formation of a pipetting channel of a pipetting device for coupling of an implement, for instance a pipette tip, or a laboratory instrument, laboratory tool or the like, thereto, wherein the coupling formation surrounds a pipetting channel section which extends along a pipetting channel axis which defines an axial direction, wherein the coupling formation additionally has, at its free longitudinal end, a pressure-imparting orifice into which the pipetting channel section opens and has, at its radially outer surface which surrounds the pipetting channel axis and extends principally in axial direction and in peripheral direction about the pipetting channel axis relative to the pipetting channel axis, a coupling projection which yields in the radial direction, which is characterized in that the coupling projection is provided so as to be essentially undeformable but radially movable on a spring arrangement which is elastic in radial direction.
