Abstract:
Device for carrying out a multiplicity of chemical, biochemical or physical processes in parallel, having at least one switching block (1) to which are fastened a multiplicity of reaction vessels (5, 5â€²) in a removable or fixed manner, it being possible for liquids, gases and/or solids to be supplied to and/or extracted from the reaction vessels (5, 5â€²) through the switching block (1), wherein the switching block (1) comprises at least one gas duct plate (11) with at least one gas duct (112) and at least one adjacent functional plate (12), at least one of these plates being arranged so that it can be displaced relative to the other, and the gas duct plate (11) or plates and the functional plate (12) or plates have through-holes (111, 121), through-slots and/or depressions (122), which are located opposite to one anothera) in at least one plate position in such a way that gases and/or liquids can be supplied to or extracted from at least two reaction vessels (5, 5â€²) simultaneously via the same gas duct (112), and b) in at least another plate position in such a way that gases, liquids and/or solids can be supplied to or extracted from at least one reaction vessel (5, 5â€²) both through the gas duct plate (11) or through at least one gas duct plate (11) and through the functional plate (12) or through at least one functional plate (12).
