Filtration Device and method for enriching target and the subsequent release of biogenic agents

The invention relates to a filtration device for enriching target and the subsequent release of biogenic agents, comprising: may have a hollow body as a container, in which a piston up as a front part of a punch in the axial direction and slide, a filter module, which is fitted to an opening at a rear end of the container and / or attached, comprising a housing and a perpendicular, that is, with its face in an axial direction oriented membrane within the housing, forming a gap between the membrane and an inner side of a side wall of the housing is arranged, wherein at least a part of the stamp can be guided through the filter module in the axial direction, and a filter formed on the module connection for a sample feed, and optionally an additional filter formed on the module connection for a sampling port. In this case, there is a fluid connection between the terminal for the sample inlet and the container, passing through the gap and the diaphragm, wherein a negative pressure in the container can be generated by an axial movement of the plunger, which allows a sample from the gap while retaining particulate components to be drawn through the vertically mounted in the filter module membrane.
