Abstract

L'invention concerne un mécanisme destiné à relier une tige de piston à un élément coulissant ou à les séparer à l'intérieur d'une pipette. Elle est caractérisée en ce que le mécanisme comprend un bloc de jonction faisant partie dudit élément coulissant et comprenant des ouvertures dont l'une loge une extrémité d'une tige de piston et l'autre l'ensemble d'une came coulissante comprenant une contre-came qu'un organe élastique pousse contre une surface de came et un plongeur s'engageant dans une gorge à l'extrémité de la tige de piston et une came à deux éléments dont le premier place ladite contre-came de façon que son plongeur soit engagé dans la gorge de la tige du piston et dont l'autre la déplace de façon que le plongeur se degage de ladite gorge. Application à la distribution de volumes de liquide précis qui doivent être mélangés avec un échantillon subissant un test dans un laboratoire médical ou un laboratoire clinique.
