1. A reaction card (1) consisting of a body, having a front surface (62) and a rear surface (63) defined by an edge (68), at least one input (2, 3, 4 and/or 5) and at least one output (7 and/or 8), connected one (2, 3, 4 and/or 5) to the other (7 and/or 8) through a network of channels (64) constituting at least one reaction path for at least one fluid (70, 71 and/or 72), the fluid or fluids being directed inside the card (1) via valves (11 to 35 and/or 61);

  • each valve (11 to 35 or 61) consists of a flexible film (67), which can be deformed to allow a fluid to pass through or which cooperates with a compression means (75) to prevent the fluid from passing through, the film (67) being fixed on the rear surface (63) of said card (1) at the peripheral indentation (74) of the assembly of channels associated with the valve (11 to 35 or 61);

    the card (1) features channels (64) flush with at least one of its surfaces (62 and/or 63), the channels (64) being of two different cross-sections, a small cross-section serving as a reaction compartment;

    each front (62) or rear surface (63) is delimited by at least one film (48, 49, 65, 66 and/or 67).
