PURPOSE:To improve the reliability on the result of measurement by preventing reagents from remaining in dispensing nozzle parts after dispensing of the reagent liquids. CONSTITUTION:The degree of the influence exerted to the reagent liquids in the succeeding dispensing operation by the reagent liquids remaining in the dispensing nozzles 11, 13 after the dispensing operation in the stage of dispensing the reagent liquids from a reagent vessel row 10 to a reaction tube row 5 contg. specimen by reagent liquid dispensing mechanisms 12, 14 is stored in a microcomputer 19. The microcomputer 19 is connected to a mechanism 2 for driving the specimen vessel row 2, a mechanism 6 for dispensing the specimen, a mechanism 8 for washing specimen dispensing nozzles, a mechanism 3 for driving a turntable, the mechanisms 12, 14, a mechanism 15 for washing reagent dispensing nozzles, a mechanism 17 for driving a specimen measuring mechanism, an analog to digital converter 18 and a mechanism 9 for washing and drying the reaction tube row and feeds signals to the respective associated mechanisms to prevent the reagent liquids remaining in the nozzles 11, 13 from affecting the succeeding dispensing reagent liquids with the stored contents as criteria. Since the analysis is thus smoothly and automatically executed, the reliability on the result of the measurement is improved. |
