Abstract

La présente invention concerne un dispositif d'échantillonnage de liquides qui comprend un tube transparent du type pipette dans les extrémités terminales intérieures duquel sont fixés deux bouchons percés qui permettent la fermeture étanche de l'intérieur du tube transparent au moyen d'une paire de sphères. Le tube transparent est plongé dans le liquide à échantillonner, le liquide entre dans le tube au moyen des orifices présents dans les bouchons et reste piégé quand le tube est sorti et les sphères restent fixes bloquant ainsi les orifices des bouchons. Outre le fait d'être transparent pour permettre une évaluation visuelle du liquide échantillonné, le dispositif comprend une base avec une tige qui traverse l'orifice du bouchon inférieur, déplace ainsi la sphère de sa position et permet de vider le liquide contenu dans le tube. Le dispositif a été conçu pour prélever des échantillons de liquides stockés dans des grandes cuves, comme l'essence, sans que ceci limite d'autres applications possibles dudit dispositif.
