Abstract

Sonde d'échantillons liquides à repère déplaçable indicatif des volumes aspirés. Un repère, une bulle d'air par exemple, est introduit à l'entrée de la sonde préalablement à chaque cycle d'aspiration, de manière à se déplacer dans le système de sonde pendant ledit cycle. L'emplacement du repère est détecté à la fin du cycle approprié a été aspiré. Le liquide aspiré est ensuite distribué, en même temps que le repère et un volume prédéterminé de diluant. Un signal d'alarme peut être actionné si un volume inexact a été aspiré. Applicable notamment à l'analyse de séries d'échantillons liquides, par colorimétrie ou autrement.
