Abstract

L'invention concerne un dispositif permettant d'absorber un liquide et comportant une membrane poreuse et un réservoir à liquide muni d'un orifice d'entrée. Ce réservoir est au moins partiellement occupé par une matière en vrac poreuse. Cette membrane est hermétiquement fermée sur le réservoir ou autour de celui-ci, de sorte que les fluides passant à travers l'orifice d'entrée doivent passer à travers la membrane, laquelle présente une dimension de pores moyenne comprise entre 1 et 100 µm.
