Abstract
A reaction card (1) having a body, a front surface (62) and a rear surface (63) defined by an edge (68), at least one inlet (2, 3, 4 and/or 5) and at least one outlet (7and/or 8), connected by a network of channels (64) constituting at least one reaction path for at least one fluid which is directed via valves (11to 36 and/or 61); each valve includes a flexible film (67) which can be deformed to allow fluid passage, the film being fixed on the card's rear surface at a peripheral indentation of an assembly of channels associated with the valve; the card includes channels flush with at least one of its surfaces, the channels being of two different cross-sections, a small cross-section serving as a reaction compartment; each front or rear surface is delimited by at least one film (48, 49, 65, 66 and/or 67).
