Abstract

A thermally sterilizable fluid filter (10) 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 (12) 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.
