<p>The filtering bag (1) comprises a filtering element (8), which divides an interior volume of a pocket (9) into two compartments by an orifice. A first compartment receives sample and a second compartment collects filtrate (10). The filtering element consists of a permeable film band whose width is lower than external sheets, and is in the form of sheet. The filtering element is fixed to the sheet by fixing lines and extended to the periphery of lateral and lower edges of the pocket to delimit sheet volume. The filtering bag (1) comprises a filtering element (8), which divides an interior volume of a pocket (9) into two compartments by an orifice. A first compartment receives sample and a second compartment collects filtrate (10). The filtering element consists of a permeable film band whose width is lower than external sheets, and is in the form of sheet. The filtering element is fixed to the sheet by fixing lines and extended to the periphery of lateral and lower edges of the pocket to delimit sheet volume. The fixing lines of the sheets are distinct from the fixing lines of film band and extended along the lateral edges of the film band. A higher edge of the bag and the filtering element are on the same level. A portion of the sheet is common to both the compartments comprising an orifice to facilitate the introduction of a pipette into the collection compartment of the filtrate (10). Adhesive elements are located in the higher part of the sheet comprising notch. The filtering element: is selected based on its width, shape, capacity of filtration, thickness, and center of the filtering element and parallelism, which are compared to its longitudinal axis of symmetry; and has a rigidity, which is different from the sheet. Independent claims are included for: (1) a support-separator to open the bag; and (2) a process of sampling the filtrate.</p> |
