Abstract

An array of valves are arranged in n columns and m lines and which are each designed to control a fluid flow in an associated flow channel in a lab-on-a-chip system. The array includes at least two valves, every column having not more than one valve and every line having from zero to n valves. A device is used for actuating the valves. The valves are pressure-actuated. To produce the device, the flow channels are arranged in accordance with the arrangement of the valves. Which valves are actuated being changeable by movement of projections relative to array of valves so as to change which valves the projections are pressed against.
