A thermally sterilizable fluid filter () for concentrating substances contained in a fluid by way of micro-, nano- or ultrafiltration of the fluid, particularly for concentrating a pharmaceutical precursor and/or intermediate, in particular a vaccine, in a fluid. The fluid filter has a filter housing with a fluid inlet, a retentate outlet and a permeate outlet. A filter cartridge is arranged in the filter housing () and has a filter medium of a ceramic material and/or a ceramic composite material. The filter cartridge is held with axial play on the filter housing.

A method for the manufacture of ceramic hollow fiber membranes in a spinning process by using a spinning mass, comprising the steps: providing a spinning mass formulation; providing a secondary phase; adding the secondary phase to the spinning mass formulation; manufacturing the ceramic hollow fiber membranes in a spinning process.

Ceramic hollow fiber membranes with improved mechanical properties

A whole blood hollow fiber membrane filter medium is made of a polymeric material having pores of a pore size that ensures permeability to blood plasma or serum but retains blood cells. The whole blood hollow fiber membrane filter medium is used for filtering a whole blood sample so that blood plasma or serum passes through the whole blood hollow fiber membrane filter medium and blood cells are retained. The obtained blood plasma shows no hemolysis.

Polymeric whole blood hollow fiber membrane filter medium and use thereof for separating blood plasma/serum from whole blood

A whole blood hollow fiber membrane filter medium is provided with a ceramic material having pores of a pore size that ensures permeability to blood plasma or serum and its molecular components while blood cells are retained. The whole blood hollow fiber membrane filter medium is used for separating blood plasma from whole blood, wherein the blood plasma preferably shows no hemolysis.

A filter membrane of a multi-layer configuration for filtration of a medium is provided with at least one first layer that has as a main component an oxide ceramic material and is provided with at least one second layer that has as a main component a non-oxide ceramic material. The first layer is a carrier layer and the second layer is a separation layer that filters the medium and generates a retentate and a permeate.

A filtering device features a ceramic filter body for filtering a fluid flow, the filter body consisting of a wavy layer and a flat layer and the wavy and flat layer being wound in a spiral-shaped manner. The wave length of the waves increases from the inside to the outside with increasing distance to the longitudinal axis of the filter body such that the wave troughs and the wave peaks of at least two radially adjacent windings each lie on a common radial plane.
