PURPOSE:To attain to enhance measuring accuracy, by performing the injection of a specimen into a cuvette and the change-over of a specimen cup and a rinse cup only by rotating an arm. CONSTITUTION:The titled apparatus equipped with a freely movable table 4 holding a turntable 2, which supports specimen cups 1, and a rinse cup 3, a cuvette 5 provided in the side opposite to the cups 1 and the cup 3 and a freely rotatable arm 8 supporting the nozzle 6 injecting a specimen in the cuvette 5 and driven by a motor 7. The sucking and emission of the specimen and the washing of the nozzle 6 with a rinse solution are performed by a syringe through a tube 11. Further, a change-over means 12 for allowing the cups 1 and the cup 3 to alternately position at the falling part of the nozzle in synchronous relation to the rotation of the arm 8 is provided to the motor 7 and the table 4. Therefore, the cups 1 and the cup 3 are changed over in synchronous relation to the rotation of the arm 8 by the change-over means 12 and the enhancement of measuring accuracy can be attained. |
