PURPOSE:To easily detect the abnormality of the discharge of liquid from cuvettes, the dispensation of cleaning liquid, etc., by detecting whether or not there is liquid in the cuvettes during the rotation of a centrifugal separating rotor from the characteristic absorption wavelength of the liquid at the cleaning stage of the curvettes. CONSTITUTION:The dispensation is performed from a sample tray 13 and a 1st and the 2nd reagent bottle receivers 6 and 7 to the cuvettes 3 on a reaction tray 2 by a pipetter 9 and the 1st and the 2nd reagent dispensers 17 and 23 and a measurement is taken after fast rotation. The tray 2 is fed stepwise after the measuring operation to inject the cleaning water in all cuvettes 3 by a cleaning water dispenser 32, and then the tray 2 is rotated at a high speed to discharge the cleaning water by a siphon phenomenon. A measuring instrument 49 for abnormality detection provided to a measurement part 30 finds the absorbance of detection light 52 passing through the reaction and light measurement part 46 of the cuvette 3 during the water discharging operation and then the absorbance of the reaction and light measurement part 46 which is clean and empty is compared with that of the reaction and light measurement part 46 which is filled with the washing liquid to detect whether or not there is abnormality. |
