The invention relates to a device for the capillary transport of a liquid between two opposite lying, essentially planar layers, whereby both layers are arranged at a distance from and parallel to one another in such a way that a capillary active gap is created between both layers. The invention is characterized in such a way that at least one of the layers comprises at least two discrete adjacent parts, and that the capillary active transport of the liquid can flow beyond the common boundary of the parts which are situated in a layer.
