Patent ID: 6989133

Claim:
An apparatus for conducting chemical reactions comprising: a reaction slider in which are formed a multiplicity of through holes serving as reaction chambers, a selector slider located on a side of the reaction slider at which the reaction chambers emerge, and having a continuous control orifice, wherein the selector slider is movable relative to the reaction slider, a chemical slider, located on the opposite side of the reaction slider to the selector slider, wherein feed holes for the supply of chemicals emerge on the surface of the chemical slider facing the selector slider, and the reaction chambers of the reaction slider and the feed holes of the chemical slider are arranged along an orbit, and the reaction slider and the selector slider may be so moved relative to the chemical slider by rotation around a common axis of rotation which passes through the centre point of the orbit that one of the feed holes, one of the reaction chambers and the control orifice may be brought into alignment, so that a through connection to supply the reaction chamber with a predetermined reagent may be made, and a device is provided for applying a force to the sliders in order to seal their contact faces, this device is acting on a connecting rod, which extends through central openings in the sliders, so that a force, which is applied by the device for applying a force to the sliders, acts in the area of the axis of rotation.
