Abstract

Pipette tenue à la main permettant la distribution répétée de volumes précis de liquide. Elle comprend à une première extrémité un bouton commandant la distribution du liquide qui est relié à un ensemble de piston et de cylindre situé à son extrémité opposée et qui peut être séparé de son corps afin d'être nettoyé ou remplacé. Un mécanisme intérieur de cliquet et de crémaillère fait avancer le piston d'une faible distance chaque fois que le bouton est abaissé de façon à distribuer d'une manière répétée de petits volumes de liquide. Un second bouton commande un mécanisme interne qui à la fois pousse le piston vers une position de dépassement dans la chambre qui le contient et qui sépare le piston du mécanisme interne du corps de la pipette. 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.
