Abstract

L’invention concerne un dispositif pour système de pipetage multicanaux, comprenant un porte-pistons (34), une tige de guidage (38) du porte-pistons montée coulissante dans un organe de guidage (40), une pluralité de pistons (20a, 20b) présentant une extrémité basse logée à coulissement dans une chambre d’aspiration, ainsi qu’une tête de piston (56) montée sur le porte-pistons par l’intermédiaire d’une liaison mécanique (62). Selon l’invention, la liaison mécanique (62) comporte deux points de contact (64a, 64b) définissant conjointement un axe de rotation de tête de piston (66) orienté orthogonalement à la direction transversale (10) et à l’axe central longitudinal (14) du système de pipetage, et le dispositif comporte en outre, associé au piston (20a, 20b), des moyens élastiques de rappel (68) forçant la tête de piston (56) vers le haut contre le porte-pistons (34), pour l’établissement des deux points de contact (64a, 64b). Figure pour l’abrégé : Figure 6.
