Abstract

A pipette for the handling of a syringe. The pipette has jaw chucks which are adjustably arranged with respect to the plunger receptacle, being pivotably mounted on a plunger-gripping device. The syringe is insertable with opened jaw chucks with the plunger head only partially contacting the jaw chucks. The jaw chucks are laterally engageable on the plunger head upon insertion of the syringe. The engaging movement of the jaw chucks on the plunger head is regulated according to the invention so that the engaging movement has a substantially tangential component with respect to the surface of the plunger head. As a result, a desired and form-locking connection to the plunger head of the syringe results that requires a small amount of force.
