Abstract

A filter element (200) and a method are disclosed for retaining particles of a medium for example (rare) cells of blood. The filter element (200) comprises at least one opening (220) that (i) has an elongate cross section and/or (ii) has a cross section that decreases in flow direction (x) and/or (iii) is bordered by a transparent wall. Preferably the filter element (100 200 300) is provided with a plurality of elongate openings (220) of stepwise decreasing cross section that are arranged on a common transparent slide. Thus high flow rates can be realized throughout the filtering process and the retained particles are immediately ready for visual inspection without a need for a further transfer.
