Abstract
Capillary filter arrangement for the sterilization of liquid media comprising two semipermeable capillary fibre bundles (4, 5) which are in flow connection and which are arranged adjacent each other in a single housing (1). The opposite openings of the housing (1) are each sealed by an end cap (2; 2a) which comprises at least one connecting opening (3; 3a) for introduction or removal of the medium respectively. The housing (1) comprises at its ends a cast layer (6; 7) in which the ends of the capillary fibre bundles (4; 5) are received, a distributing space (8; 9) being formed between the end cap (2; 2a) and cast layer (6; 7) and a primary filtrate chamber (10) being formed between the cast layer (6; 7). The ends of the first capillary fibre bundle (4) are sealed with respect to the first distributing chamber (8) and the ends of the second capillary fibre bundle (5) are sealed with respect to the second distributing chamber (9 ) so that the entire internal lumen of the first and second capillary fibre bundle (4; 5) respectively is in flow connection only with the second and first distributing chamber (9; 8) respectively.
