ABSTRACT:
A filter, in particular for the separation of leucocytes from further blood components, has an outer sheath, at least one intermediate layer which is a component of a frame or which forms a frame, an inlet chamber which is in communication with an inlet for the medium to be filtered, an outlet chamber which is in communication with an outlet for the filtrate, and a filter material which separates the inlet chamber from the outlet chamber. The filter is particularly low in dead space and can be centrifuged in a simple manner since the filter material is encompassed between the outer sheath and the intermediate layer.
