Abstract
The invention relates to a flow cell comprising a layered arrangement of three plates (3-5) in which an intermediate plate (4) consisting of a flexible material is inserted between plates (3, 5) consisting of a more solid material, and at least one of the plates comprises at least one recess (15, 17) for receiving fluid, that is bordered by another plate (3, 5) of the layered arrangement. Such recesses are especially microchannels and reaction chambers. According to the invention, the plates are interconnected by means arranged parallel to the plate plane at a distance to the recess, compressing the intermediate plate.
