PURPOSE:To obtain always the same measurement results in the case of measuring the same items of the same samples regardless of the number of measurement items by subjecting all the reaction cells corresponding to the total number of the measurement items to dispensing of the samples at all times. CONSTITUTION:A sample dispenser 11 is disposed to the position P1 on the outer periphery of an annular thermostatic chamber 10. Many kinds of the samples 11a, 11b, 11c... which are kept housed in the thermostatic chamber are held in the dispenser 11. A reagent dispenser 13 is disposed in the position P2 and many kinds of the reagents 13a, 13b, 13c... which are kept housed in the thermostatic chamber are held in the dispenser 13. All the reaction tubes 15 are first subjected to dispensing of the sample 11a successively by a tube 12 regardless of the presence or absence of the measurement. The reagent necessary for the measurement item is then selected by a tube 14 and the reagent is successively dispensed into the cells 15. The reaction cells to be measured of the same items are subjected to the sample dispensing always at the same suction length in the above-mentioned manner regardless of the number of the measurement items and, therefore, the fluctuation in the concn. at every measurement is obviated. |
