ABSTRACT:
Analysis apparatus which uses a solid reaction support designed to hold successively a quantity of a compound such as a biological liquid which contains a substance to be analyzed, and then a quantity of a first reagent on which is fixed a biological indicator. The apparatus is constituted by an analysis rotor (1) which includes a plurality of peripheral reaction cells (2) each of which contains said reaction support (3), said cells being provided with a peripheral liquid-removal orifice (7). Means (4, 5) convey a washing liquid towards each reaction cell. Each of said reaction cells (2) is associated with a buffer cell (10), which successively receives at least the compound and the first reagent. It shares a common wall (11) with the reaction cell (2). A passage (25) is provided between the cells of each pair through said common wall (11). The first reagent is contained in a suitable receptacle (14) supported by the analysis apparatus. Means are provided to open said receptacle (14) to pour the reagent into the buffer cell (10).
