Abstract: This analysis unit (2) comprises a rack (11) suitable for receiving at least a first and a second container (3a, 3b), and an agitating device (22) suitable for mounting on the rack (11), the agitating device (22) being designed to drive at least the first container (3a) in rotation when the agitating device cooperates with a drive unit of an analysis device. The agitating device (22) comprises coupling means designed to rotationally couple at least the first and second containers (3a, 3b) held on the rack (11), the coupling means being configured to drive at least the second container (3b) in rotation when the first container (3a) is driven in rotation by the agitating device.

Abstract: The device comprises reaction unit cuvettes (22) for different types of tests, a vertical axis rotor (7) which is associated with a rotation drive means and provided with a horizontal gear-teeth crown (8) delimiting radially outwardly open cavities for receiving the reaction unit cuvettes (22), a device (20) for supplying the gear-teeth crown with the reaction unit cuvettes (22), a device (6) for supplying cuvettes with analyzable biological liquid samples, stations (13, 19) arranged around the crown for carrying out measurements and/or analysis and an automation for managing the sequences of a desired process for each cuvette.

Abstract: The bottom of the cuvette 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 in a feed magazine of an analytical device. The analytical device comprises several stations placed around a rotary ring. 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. The cuvette equipped in this way is then brought to a station where the test is carried out. The major advantage of the invention is the polyvalence of the cuvette and of the analytical device.
