Abstract

The invention relates to an apparatus for separating blood, more particularly an apparatus (1) for absorbing blood (19) and separating blood components, e.g. blood plasma, as a sample liquid (2). Said apparatus (1) comprises a feeding device (13) for absorbing the blood (2), a device (15) for separating blood components as a sample liquid (2), a duct which preferably absorbs the sample liquid (2) exclusively by means of capillary forces, and a device for filling the duct (3) with sample liquid (2) in an inlet or feeding zone (18) of the duct (3). The separating device (15), in particular a membrane, is curved, especially convexly shaped, and the apex of said curved, especially convex shape projects into the filling device.
