Abstract

A method and apparatus for reacting a plurality of different mixtures in parallel in a semi-batch or continuous mode is provided. Each reaction is contained within a reactor vessel, the reactor vessels combined into a reactor block. Reactant(s) to be added during the reaction are kept in a header barrel, which has a plunger to feed reactant(s) from the header barrel through a transfer line into the reactor vessel. The plunger is moved using a drive system. The header barrels are optionally combined in a header block. The header block is sealed to a plate containing the transfer lines, which in turn is sealed to the reactor block. A latch mechanism is provided for easy sealing of the reactor and header blocks to the plate. The entire apparatus may be placed on a rocker or rotating plate for mixture as the reaction is proceeding.
