Abstract: Filter module and filter unit with an inlet for medium that is to be filtered, and with an outlet for the permeate, with at least one filter sheet, a first spacer adjacent to the media side and a second spacer adjacent to the permeate side, the spacers being designed with a draining action, and the first spacer being connected to an inlet and the second spacer to an outlet, wherein the at least one filter sheet forms a first filter unit together with the two adjacent spacers, the filter sheet is designed as a single filter or a filter stack, the first spacer is designed to be impermeable to liquid on its outer face directed away from the filter sheet and is sealed off at its boundary to the outlet end, and the second spacer is designed to be impermeable to liquid on its outer face directed away from the filter sheet and is sealed off at its boundary to the inlet end.

Abstract: The invention relates to the use of single- or multilayer plastic web plates in a sloped channel-type solid material separator with a lamella package.

Abstract: The invention relates to a separator for retaining and recirculating cells in a continuous-flow or batch-flow type plastic bag or bottle, which can preferably be operated outside of a bioreactor. Additionally, the invention relates to a method for retaining and recirculating cells within or outside a bioreactor. The invention further relates to a method for producing the separator according to the invention.
