Abstract

An apparatus for carrying out chemical reaction sequences includes a stack of reaction plates arranged one above another and displaceable according to choice step by step in relation to one another, which are provided with passages arranged at the stepping interval, one of which passes in each case is formed as reaction chamber. A plate displacement device serves for the displacement of the respective plate, according to choice, in relation to the remaining plate stack. A pressure application part of a clamping device is provided with a faculty for movement of the plates in relation to one another between a pressure application position with sealing clamping together of the plates and a release position. A force transmission device in the form of a two-armed lever couples the plate displacement device with the pressure application part, so that on a movement of the plate displacement device beyond one of the two outer plate displacement positions into an end position the pressure application part is moved into the pressure application position.
