Abstract
The invention relates to a device for microfluid analyses for a substrate with plane base surface and cover surface, wherein a chamber is integrated in the substrate for receiving liquid with at least two admissions and a semipermeable or permeable membrane is arranged in the chamber, wherein the chamber is subdivided by the membrane into two sectional chambers with at least one admission each.

Device for microfluid analyses with a substrate with plane base and cover surfaces, wherein
- a chamber for receiving liquid comprising at least two admissions is integrated in the substrate, and
- in the chamber a semipermeable or permeable membrane is arranged, the chamber being subdivided into two sectional chambers with at least one admission each by the membrane,
- wherein the substrate comprises a covering element, in the base surface of which a recess for the chamber is provided, and
- wherein the covering element comprises an intermediate plate in which an opening for the chamber is provided, and a cover plate which is provided for covering the opening on one side of the intermediate plate.
