CONE EJECTION SYSTEM WITH IMPROVED ERGONOMICS FOR A PIPETTE

摘要

A taper ejection system (2) for a sampling pipette, the system comprising: - a cone ejection button (25) for translational movement by the thumb (4) of an operator ; a cone ejection device (24); - Elastic return means (32) for returning the device (24) for ejection of cone in a high position. According to the invention, the system further comprises a lever (40) for controlling the ejection device (24), the control lever comprising: - a first end (40a) intended to be mounted on a piece of (46) the pipette; - a second end (40b) cooperating with said ejection button (25), so as to be solicited by it; an intermediate portion (40c) for actuating the ejection device (24).
