Abstract

L'invention concerne une pipette pour aspirer les liquides pour l'analyse d'échantillons. Une pipette aspirante 16 se déplace d'une position inférieure où elle est plongée dans un liquide d'un récipient 12, à une position supérieure dans laquelle elle est dégagée du récipient, en entraînant dans son mouvement vers le haut un dispositif de lavage 28 qui permet de laver l'intérieur et l'extérieur de la tige 24 de la pipette lorsqu'elle est dans la dernière position indiquée. La pipette de l'invention est particulièrement utile pour aspirer et éventuellement distribuer des échantillons de liquides, aspirer et éventuellement distribuer des échantillons de liquides, notamment le sérum sanguin, dans l'analyse automatique d'échantillons en écoulement continu.
