An apparatus for filling a sample volume defining device for separating at least one small defined volume of a liquid sample from a relatively larger undefined volume of said sample, said device including a first body (A) and a second body (B) movable relative to each other, whereby said first body has at least one cavity in a surface thereof, said at least one cavity having said defined volume. One of said first or said second body (A, B) has at least one inlet opening (C) adapted to be placed in a drop of the liquid sample. A defined channel is provided between said first and second body, which channel has fluid connection with said at least one opening (C) and at least beyond said at least one cavity whereby the dimensions of said channel being such that said channel and said at least one cavity is filled with said liquid sample.

L'invention concerne un appareil permettant de remplir un dispositif formant un volume d'échantillon de manière à séparer au moins un petit volume formé d'un échantillon liquide d'un volume non formé relativement plus important dudit échantillon. Ce dispositif comprend un premier corps (A) et un second corps (B) mobiles l'un par rapport à l'autre, ledit premier corps présentant au moins une cavité dans une surface correspondante et ladite cavité contenant ledit volume formé. Un corps parmi lesdits premier ou second corps (A, B) présente au moins une ouverture d'entrée (C) conçue pour être placée dans une gouttelette de l'échantillon liquide. Un canal formé se trouve entre lesdits premier corps et second corps, ledit canal possédant une liaison fluidique avec ladite ouverture (C) et au-delà de la cavité, les dimensions du canal étant telles que le canal et la cavité sont remplis avec l'échantillon liquide.
