Abstract

La présente invention concerne une pipette réglable de distribution d'échantillons liquides. La pipette selon l'invention comporte un boîtier incorporant un mecanisme de réglage du volume et un ensemble indicateur de volume; un embout qui comporte une tubulure latérale d'alimentation munie de moyens permettant l'adaptation étanche d'un réservoir; une chambre de mesures ménagée dans ledit embout de manière à recevoir, avec un faible jeu, un piston calibré élastiquement vers le haut et dont l'extrémité supérieure coopère avec une butée de limitation de course vers le haut, réglable en position au moyen du mécanisme de réglage; une tige de commande dont l'extrémité inférieure coopère avec l'extrémité supérieure du piston calibré et des moyens assurant l'étanchéité de la chambre de mesures. Application à la distribution continue de liquide.
