The device (1) has a central body (2) forming a stopper with a traversing channel. The traversing channel emerges at the level of an end (2a) of the stopper inside a tubular filter (4) and at the level of another end (2b) of the stopper. The tubular filter has two longitudinal portions respectively having different porosities. The end are associated with external threadings (5, 6), respectively, where the threadings are realized rotationally in a same direction.
