Abstract
A device for carrying out a multiplicity of chemical, biochemical or physical processes in parallel has a plurality of switching blocks ( ), to which a multiplicity of reaction vessels ( ) are removably fastened. Liquids, gases and/or solids can be supplied to and/or extracted from the reaction vessels ( ) through the switching blocks ( ). Each switching block ( ) comprises a gas duct plate ( ) and a functional plate ( ) which is arranged so that it can be displaced on it. The gas duct plate ( ) has a multiplicity of through-holes, a gas duct and a multiplicity of gas duct holes extending from the gas duct to the functional plate ( ) and the functional plate ( ) has a multiplicity of through-holes and depressions open to the gas duct plate ( ). Depending on the position of the plates, through-holes, depressions or sealing surfaces of the functional plate ( ) are located opposite to through-holes and gas duct holes of the gas duct plate ( ).
