REACTION BLOCK ASSEMBLY FOR CHEMICAL SYNTHESIS

摘要

The reaction block assembly (20) comprises a reaction block (12) containing a plurality of reaction wells (14). Influent and effluent ducts (38, 38', 39, 39') open at the upper face of the reaction block adjacent each to each of the reaction wells. These ducts provide communication between each reaction well and a source of reagents and gases and with waste removal means for removal of effluent from the reaction wells. A membrane sheet (28) overlies the upper face of the reaction block to define a pneumatic valve to open and lose the duct openings. The reaction block assembly preferably includes a temperature control block (16) that underlies the reaction block for control of the temperature in the reaction wells. Overlying the reaction block is a top manifold plate (18) block for delivery of high pressure gas to actuate the pneumatic valves by applying pressure against the membrane to seal the duct openings.
