Abstract

A bioreactor having a filter unit and a method for treating a cell broth. The filter unit has a supply channel (2), a first filter medium (4), a retentate channel (1), a second filter medium (5) and a permeate channel (3), arranged so that the first filter medium delimits the supply channel and the retentate channel from one another; and the second filter medium delimits the retentate channel and the permeate channel from one another. The supply channel is connected to an inlet for a supply medium; the retentate channel is connected to an inlet for a cell broth and to an outlet for the cell broth; the permeate channel is connected to an outlet for a permeate; and the interior of the bioreactor is connected to the inlet for the cell broth and to the outlet for the cell broth.
