The bottom of the cuvette (1) comprises a curved raceway placed so as to guide the oscillating movement of a ball inserted into the cuvette. In addition, the cuvette comprises means of attachment, in two perpendicular directions, to adjacent unit cuvettes. The cuvettes can thus be stored as plates (19) in a feed magazine (27) of an analytical device (22). The analytical device comprises several stations (29-37) placed around a rotary ring (25). Only where it is desired to determine the clotting time of the blood contained in the cuvette a ball is introduced into the latter, at a ball distribution post (36). The cuvette equipped in this way is then brought to a station (37) where the test is carried out. The major advantage of the invention is the polyvalence of the cuvette and of the analytical device. |
