摘要
The invention relates to a filtration assembly (5) comprising an annular support (12) which comprises an annular step (13) having an apex on which a filter membrane (11) rests, and a cover (20) covering the annular support in order to hold a periphery of the membrane between the cover and the annular support. The cover comprises a ring (21) which fits around the step to trap the periphery of the membrane between the ring and the annular support, the ring being extended by a skirt (22) which extends as a projection from the ring to cover an external peripheral wall of the annular support and to exhibit an end face (23) which extends in continuity with a bearing face (24) of the annular support. The invention also relates to a removable cassette for an apparatus for sampling nanoparticles comprising such a filtration assembly.
