Abstract

L'invention concerne l'industrie du matériel de laboratoire. Pompe volumétrique à seringue 124 associée à une soupape 112; le plongeur 152 de la seringue effectue un mouvement de va-et-vient par entrée en contact avec un chariot 24 entraîné par un moteur et comportant une barre transversale inférieure pour pousser une tige de mesure 170 sélectionnée contre le plongeur, ainsi qu'un organe de support 56 qui entre en contact avec le plongeur pour le faire descendre, ce qui permet d'aspirer et de refouler une quantité de liquide sélectionnée déterminée par la longueur de la tige de mesure choisie parmi plusieurs qui sont logées dans un plateau tournant 164. Application notamment au prélèvement d'échantillons dans des buts d'analyse.
