Abstract

La présente invention concerne une pipette réglable de distribution à répétition de solutions ou de suspensions. La pipette selon l'invention comprend en combinaison un boîtier incorporant un mécanisme de réglage du volume à distribuer et un ensemble indicateur dudit volume; une seringue adaptable à l'extrémité inférieure dudit boîtier; un piston apte à se déplacer à l'intérieur de ladite seringue; une tige de commande du piston dont l'extrémité supérieure sortant dudit boîtier est munie d'un bouton de traction; un levier d'entraînement au coup par coup de la tige de piston, qui est apte à se déplacer et entraîner ladite tige de piston selon une course predéterminée. et qui comprend une première partie traversée par un orifice permettant le passage avec un faible jeu de ladite tige de piston et une seconde partie s'étendant sensiblement de façon perpendiculaire à l'axe dudit orifice, et un organe de commande de la distribution agencé pour exercer une force de pression sur le levier d'entraînement Application aux instruments de laboratoires.
