Abstract

A device for dosing amounts of liquid in desired volumes, comprises piston means (3) movable in a cavity (4) of casing means (2) for collecting an amount of liquid from an inlet (12) of said casing means (2) and directing said amount of liquid towards an outlet (13) of said casing means (2); said piston means (3) is provided with commutating means (8) such to selectively make communicating said cavity (4). with said inlet (12) or with said outlet (13), said commutating means. (8) being provided with an operating end (8a) suitable for being faced to at least said outlet (13) in order to define with said outlet (13) an outflow wall such to inhibit the adhesion of possible air bubbles,- a moving apparatus for a dosing device comprises first actuating means (41) and second actuating means (42) removably connectible. with a lower end portion (5) of piston means (3) of said device (1) in order to linearly and rotationally move said piston means (3).
