The invention relates to a device for separation of substance mixtures on the micro scale. The invention further relates to a process for separating substance mixtures using the inventive device. The device is a device for separating substance mixtures and for performing chemical reactions between immiscible fluid media on the micro scale, comprising a first channel plate with at least one first process channel for a first fluid medium, an inlet and an outlet, and a connecting or distributing channel in each case, which connects the inlet to the first process channel, and a further connecting or distributing channel which connects the first process channel to the outlet, a second channel plate with at least one second process channel for a second fluid medium immiscible with the first, an inlet and an outlet, and a connecting or distributing channel in each case, which connects the inlet to the second process channel, and a further connecting or distributing channel which connects the second process channel to the outlet, and a microscreen as a separating means between the two process channel, wherein the microscreen has a multitude of orifices which have an aspect ratio of 1.5 to 10.
