Abstract

La présente invention concerne un diluteur ajustable. Ce diluteur comporte un organe d'ajustage 1010 de la course du premier piston, présentant sur sa surface extérieure un filetage 1018 apte à coopérer avec un filetage 1020 ménagé sur la surface intérieure du boîtier 120, l'extrémité inférieure dudit organe d'ajustage 1010 jouant le rôle de butée de limitation de course vers le haut du premier piston; un organe tubulaire d'ajustage 1026 dont l'extrémité inférieure présente une surface de butée 1028 apte à coopérer avec l'extrémité supérieure 1030 du manchon de commande 460 du premier piston et dont la surface intérieure présente un filetage 1032; et un élément poussoir tubulaire 500 solidaire de la tige de commande 480 du second piston présentant un filetage extérieure 1036 apte à coopérer avec le filetage intérieur 1032 de l'organe tubulaire d'ajustage 1026. Application au matériel de laboratoire.
