Abstract

Pipettes à échantillons utilisées en particulier pour l'injection d'échantillons dans des appareils de chromatographie liquide à haute pression, qui sont pourvues d'une aiguille creuse (4) destinée à prélever un échantillon et à expulser ce dernier dans un récipient ou dans le dispositif récepteur d'échantillon de l'appareil. Une canule interchangeable (7) est montée sur l'aiguille creuse d'une pipette de ce type, ladite canule pouvant contenir des éléments fonctionnels supplémentaires (12) tels que des filtres, des phases chimiquement actives, etc.
