The invention relates to a valve for sampling a fluid from the same collecting vessel in order to carry out a plurality of analyses using reagents. The valve of the invention includes two members (1, 2) mobile relative to each other, including a so-called sampling member (2) that comprises sampling loops each intended for receiving an aliquot of fluid, and another so-called connection member (1) capable of assuming at least three distinct functional positions relative to the sampling member. These three positions enable the delayed access to two separate sampling circuits for filling the same, and for supplying the loops forming them, with reagents.
L'invention concerne une vanne d'échantillonnage, à partir d'un même récipient de prélèvement, d'un fluide en vue de plusieurs analyses utilisant des réactifs. La vanne selon l'invention comprend deux éléments mobiles (1,2) l'un par (2) comprend des boucles d'échantillonnage, chacune destinée à contenir un aliquote du fluide et un autre élément dit de connexion (1) destiné à prendre au moins trois positions fonctionnelles distinctes relativement à l'élément d'échantillonnage. Ces trois positions permettent d'accéder de manière différée à deux circuits d'échantillonnage distincts pour les remplir et pour dispenser les boucles qui les constituent en réactifs.
