Patent ID: 7172735

Claim:
A modular microreaction system comprising a housing and functional base modules accommodated therein, the housing having at least one fluid inlet and at least one fluid outlet, the base modules being arranged one behind another in a row in the housing and being designed such that fluid can flow successively through them in series, and at least some of the base modules being constructed from a plurality of, substantially rectangular foils having plate-like surfaces in essentially parallel planes which foils are connected to one another and are arranged in layers one above another, forming a foil stack, at least a first of the foils comprising at least on of microstructured channels, sensor elements, heating elements and combinations thereof on at least one plate-like surface of the at least a first of the foils and each foil stack having at least one foil which is provided on a plate-like surface of the at least one foil with channels which are constructed such that for one fluid line they lead from one side of the foil stack to another side of the foil stack, wherein the base modules ( 2 , 2 â€², 2 â€³) each have at least one frame element ( 10 ), which is arranged essentially perpendicular to planes of the foils and is connected to the foil stack in a fluid-tight manner and the foil stacks, together with the frame elements, form base elements that, can be inserted into and removed from the housing ( 1 ) as a unit.
