Tip vessel for use in connection with a dosage pipette

摘要

A disposable pipette tip vessel intended for use in connection with a dosage pipette. The lowest point of the tip vessel has a hole for suction of the liquid to be pipetted into the tip vessel and, correspondingly, for emptying of the tip vessel of the liquid contained therein. In the bottom part of the tip vessel around the filling and emptying hole, a plane or gently conical bottom portion has been shaped so that the tip vessel is arranged so that, between subsequent dosage steps to be performed by means of the pipette, the tip vessel allows the air column to be sucked into the bottom part of the tip vessel to rise as an air bubble or as bubbles of air above the liquid in the tip vessel, whereby the liquid column is correspondingly lowered to the bottom of the tip vessel.
