<p>A flexible inflatable polymer film filter assembly or device (10) is provided in pouch or sleeve form for filtration of fluid comprising at least one fluid porous dead-end filter panel (20) located internally within the pouch or sleeve with the opposite end edges (20C, 20D) of the filter panel (20) sealed respectively to first and second polymer film fluid-barrier panels (30, 40) that form the pouch or sleeve so that the respective pouch or sleeve is divided into separate internal chambers, one of which may serve for collection of permeate fluid. The device (10) has a flat two-dimensional form when empty but can assume an inflated three-dimensional form when containing fluid under pressure. The device being constructed of sterilizable thin plastic film, can be cut into transverse segments (for purposes of analysis, further processing, etc.) which can be a segment comprising each filter panel (20) or a segment containing a liquid or non-liquid fluid permeate. The assembly optionally includes a hollow vessel support (90) member for supporting the filter device (10) vertically for gravity flow or forced flow of liquid to be filtered, especially in the laboratory or in the field.</p> |
