The invention proceeds from an apparatus for analyzing reactions, comprising a starting material distributor and at least two reactors which are connected in parallel and are each connected via a connecting conduit to an outlet of the starting material distributor. To set the inflow, a pressure regulator and a restrictor are installed in each connecting conduit between the starting material distributor and the reactors or an outlet conduit in which a restrictor and a pressure regulator are installed branches off from each connecting conduit. The invention further relates to a method for analyzing reactions in such an apparatus.
