Abstract
A filter module for sterile filtration and virus filtration of fluid media. The filter module includes a filter membrane with a porous edge structure arranged thereon and at least one anchoring element. The filter membrane with the porous edge structure is embedded in the anchoring element and serves as edge reinforcement to improve the connection of the filter membrane to the anchoring element. The texturing or surface roughness of the edge reinforcement provides an interlocking effect between the filter membrane and the anchoring element. The embedding of the filter membrane in the anchoring element provides a fluid-tight connection of the membrane to the anchoring element which prevents the occurrence of leaks in the end region of the filter module. A method for producing the filter module is also described.
