A cartridge (20) for conducting a chemical reaction includes a body having at least one flow path formed therein. The cartridge also includes a reaction vessel (40) extending from the body for holding a reaction mixture for chemical reaction and optical detection. The vessel (40) comprises a rigid frame defining the side walls of a reaction chamber. The frame includes at least one channel connecting the flow path to the chamber. The vessel also includes flexible films or sheets attached to opposite sides of the rigid frame to form opposing major walls of the chamber. In addition, at least two of the side walls are optically transmissive and angularly offset from each to permit real-time optical detection of analyte in the reaction chamber.

L'invention concerne une cartouche (20) s'utilisant pour réaliser une réaction chimique et comprenant un corps doté d'au moins une voie d'acheminement formée à l'intérieur. La cartouche comprend également une cuve à réaction (40) s'étendant à partir du corps et servant à soutenir un mélange réactionnel pour la réaction chimique et la détection optique. La cuve (40) comporte un cadre rigide définissant les parois latérales d'une chambre de réaction. Ce cadre comporte au moins un canal reliant la voie d'acheminement à la chambre. La cuve comprend également des pellicules ou feuilles souples, fixées à des côtés opposés du cadre rigide afin de former les parois opposées principales de la chambre. En outre, au moins deux des parois latérales sont transparentes et décalées d'un point de vue angulaire afin de permettre une détection optique en temps réel de l'analyte dans la chambre de réaction.
