Abstract

La présente invention concerne une pipette manuelle (10) comportant une assistance par aimant (26) destinée à produire une force magnétique s'opposant à la force d'un ressort de rappel (18) agissant sur l'ensemble piston (16), et aider ainsi l'utilisateur de la pipette à placer et à maintenir l'ensemble piston en position de 'repos' à l'intérieur d'un corps (12) de pipette. La pipette est ainsi prête à l'introduction de son bout (15) dans un liquide à aspirer dans le bout.
