Use of a filter module for filtering a biotechnical liquid and filter module for the filtration of a biotechnical liquid

A filter module for filtration of a biotechnological liquid, said filter module comprising:

• a. a filter housing,
• b. a filter arranged in the filter housing with a bundle of hollow fibres,
• c. a centrifugal pump rotor arranged in the filter housing such that the centrifugal pump rotor is fluidically connected to an interior of the hollow fibres, wherein the centrifugal pump rotor is able to be magnetically driven and the centrifugal pump rotor is configured to force the biotechnological liquid into the hollow fibres such that the biotechnological liquid flows through the hollow fibres parallel to a longitudinal axis of the filter,
• d. a first port for the supply of the biotechnological liquid to be filtered, which said first port is fluidically connected to the interior of the hollow fibres, wherein an inlet flow path is defined such that the biotechnological liquid is flowable into the filter housing to the centrifugal pump rotor, the inlet flow path being perpendicular to the longitudinal axis of the filter, and the inlet flow path is designed such that the biotechnological liquid flows into a hollow centre of the centrifugal pump rotor and the biotechnological liquid is deflected such that the biotechnological liquid thereafter flows parallel to the longitudinal axis of the filter and enters the hollow fibres of the filter by the centrifugal pump rotor forcing the biotechnological liquid into the hollow fibres,
• e. a second port for the removal of the biotechnological liquid to be filtered, which said second port is fluidically connected to the interior of the hollow fibres,
• f. a third port for the removal of precipitated waste liquid, which said third port is fluidically connected to an exterior of the hollow fibres.
