Summary:A liquid filter assembly, for the analysis of particles or biological contaminants, having a reservoir (1) and a filter cartridge (2) with a membrane to retain the solids and microorganisms, is new. The reservoir is under pressure from a bottle (4) of compressed gas. The reservoir is transparent, and has marked graduations, with the filter cartridge fitted to the reservoir cap (7) at the threads (8). L'invention concerne les dispositifs de filtration destinés aux usages diagnostiques.Le dispositif de l'invention est du type comportant un réservoir supérieur pourvu d'un ensemble de pressurisation autonome constitué par au moins un accumulateur de gaz sous pression. Le réservoir supérieur est associé à une cartouche de filtration permettant d'envoyer au laboratoire la seule cartouche de filtration.Le dispositif selon l'invention permet à toute personne de procéder directement à la filtration de l'échantillon prélevé sans qu'il soit nécessaire de transporter le prélèvement liquide au laboratoire.
