Abstract

Dans une pipette à volume réglable, comportant un ensemble formant corps 10, un tube de pipette 11, un ensemble plongeur 12 et un ressort de compression 14, on introduit un manchon 15 de réglage volumétrique comportant une série de fentes 15a, 15b et 15c, parallèles à l'axe du corps, lesdites fentes étant espacées angulairement et ayant des longueurs pratiquement égales à des longueurs choisies de la course du mouvement du piston. Un contact 19 est placé sur l'ensemble plongeur et peut s'aligner sélectivement à lune quelconque des fentes, ce qui est facilité par l'existence de marques 21 sur le bouchon 16 et d'une ligne de référence 22 indiquant la position sur le bouton 20. La longueur de la fente dans laquelle s'engage le contact 19 limite la course du mouvement du plongeur et règle donc le volume de liquide prélevé et délivré par le tube de pipette.
