Abstract

A device (1) and method for media filtration with a preparation container (2). A chamber (5) containing a dissolvable medium (29) is situated between the container inflow and outflow, and has a filter (22). A mixing arm (6, 7), connected to the inflow, protrudes into the medium in the chamber with at least one mixing nozzle (19, 20), disposed at the free end (17, 18) of the mixing arm for generating a directed jet of solvent. The preparation container has bottom (10) and top (8) parts bracketing the chamber. The filter is a sterile, has on the filtrate side facing the outflow, a circumferential outer edge (23) resting on a circumferential rest edge (37) of the bottom part of the preparation container and is connected fixedly thereto. A sterilised filtrate space (39) is formed between the filtrate side (38) of the filter and the outflow situated in the bottom part.
