The invention relates to a filtration assembly () comprising an annular support () which comprises an annular step () having an apex on which a filter membrane () rests, and a cover () 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 () 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 () which extends as a projection from the ring to cover an external peripheral wall of the annular support and to exhibit an end face () which extends in continuity with a bearing face () of the annular support. The invention also relates to a removable cassette for an apparatus for sampling nanoparticles comprising such a filtration assembly.

Removable cassette for an apparatus for sampling nanoparticles present in an aerosol, and filtration assembly for such a cassette

An assembly for picking and transporting nano-objects, comprises a cassette having first and second components, which are provided with means of mutual assembly and with means for holding the filter. The first and second components define, when the components are in an assembled configuration, a cavity in which the filter is housed and held therein. The means of mutual assembly comprise first clipping means secured to the first component, second clipping means secured to the second component and able to collaborate with the first clipping means so as to clip the two components together. A picking device comprises suction means to which the cassette is able to be removably attached. The first and second clipping means are configured such that they are not accessible from the outside when the components are in the assembled configuration with the cassette fixed to the device.
