摘要

Device for the filtration of a plurality of fluid samples (46), liquids or gases, containing particles to be filtered, such as bacteria, cells or other elements, particularly contained in milk or blood, comprising at least one filter (2a, 2b) and means allowing the simultaneous and independent filtration, on the same filter, of said fluid samples. These means include at least one seal (3) which is comprised of a plurality of perforations throughout its thickness and which is maintained sealingly tight against one face of the filter (2a, 2b) by appropriate clamping means (7a, 7b), said perforations communicating at an upstream end, by interpositioning of the filter (2a), with a plurality of independent inlets of fluid samples to be filtered, and at a downstream end with a plurality of outlets, also independent, for said samples.
