Abstract

Dispositif servant à doser des quantités de liquide en volumes désirés et comprenant un piston (3) mobile dans une cavité (4) de boîtier (2) afin de prélever une quantité de liquide depuis une entrée (12) dudit boîtier et de diriger ladite quantité de liquide vers une sortie (13) dudit boîtier. Ledit piston (3) est pourvu de moyens de commutation (8) permettant à ladite cavité (4) de communiquer de façon sélective avec ladite entrée (12) ou ladite sortie (13), lesdits moyens de commutation (8) comportant une extrémité opérationnelle (8a) conçue pour être placée en face de ladite sortie (13), de manière à définir avec ladite sortie (13) une paroi de sortie empêchant l'adhérence d'éventuelles bulles d'air. Appareil mobile associé au dispositif de dosage et comprenant des premiers moyens d'actionnement (41) et des deuxièmes moyens d'actionnement (42) pouvant être accouplés de façon amovible avec une partie d'extrémité inférieure (5) du piston (3) dudit dispositif (1) afin d'imprimer un déplacement linéaire et une rotation audit piston (3).
