Date May 3, 1990.A filter apparatus for filtering a plurality of liquid or gas fluid samples containing particles to be filtered, such as bacteria or cells. The apparatus includes a filter; a device for simultaneously and independently filtering fluid samples on the filter; and apparatus for force filtering the samples. The device for simultaneously and independently filtering fluid samples includes at least one gasket including a plurality of through perforations held clamped in a sealed manner against one face of the filter by appropriate clamps. The clamps have perforations located for being brought into alignment with the perforations through the gasket and for cooperating therewith to put an upstream face of the gasket into communication, via the filter, with a plurality of independent inlets for samples of fluid to be filtered, and to put a downstream face of the gasket into communication with a plurality of likewise independent outlets for the fluid samples. The perforated clamps and the gasket define on the filter a plurality of independent and mutually sealed filter zones adapted to have the fluid samples passing in parallel therethrough under drive from the force filtering apparatus. Apparatus is also provided for indexing the filter. |
