Flow cell consisting of layer and connection means

Flow cell with a layered arrangement of three plates (3-5), in which an intermediate plate (4) made of a flexible material is held between plates (3, 5) made of a more rigid material, the intermediate plate (4) having at least one recess (16, 17) forming a chamber (17) and/or a connecting hole (16;

• 78, 79;
• 85, 87;
• 96;
• 102, 103) for holding fluid, wherein the plates (3-5) are connected with one another by connecting means (12, 13, 18) arranged some distance from the recess (15, 17) in the direction parallel to the plane of the plates in such a way that the intermediate plate (4) is compressed, wherein at least one of the plates (3, 5) of rigid material has at least one recess (10) open toward the intermediate plate (4) that forms a holding seat for a separately prefabricated microcomponent, wherein the recess (10) having a shoulder forming a through opening in the plate (3) or the recess (10) only being open on one side toward the intermediate plate (4), wherein the microcomponent (6) is held in the recess (10) by positive engagement and is bordered on a side facing away from the recess (10) by the recess (16, 17;
