摘要

A pipette arrangement comprises a body (10) with a tip (11) having a distal end (12); a tip ejecting unit (20) fitted between the distal end and the upper end of the body; and an operating unit arranged in the upper section of the body to interact with the ejecting unit. The operating unit has a tappet element connected with the body using a tilting connection and having an upper surface suitable for contact with the upper side of the ejecting unit to move the ejecting unit in the direction of the longitudinal axis of the pipette arrangement to eject the tip from the distal end. Preferred Features: The pipette additionally has a spring element suitable to return the ejecting unit and the operating unit into their starting positions after ejecting the tip.
