Abstract

The invention relates to a device for sample separation, particularly for blood separation, in which the sample liquid is introduced into a feed device. The sample flows vertically through a separating device such as a filter or a membrane, so that sample particles are retained and separated off.The sample liquid thus separated, particularly blood plasma, is received by an inlet chamber underneath the separating device and conveyed by means of a channel in the lateral direction out of the inlet chamber.Particularly advantageously, the channel extends into the inlet chamber, the channel being formed by a recess in the base of the inlet chamber.
