PURPOSE:To make possible the high-speed treatment of specimens by a random access method while maintaining the high accuracy of measurement by providing a reagent table part and reagent dispensing nozzle parts in such a manner that these parts can be housed in a small space. CONSTITUTION:The reagent table part 14 and the reagent dispensing nozzle parts 19, 20, etc. are provided. The 1st nozzle part 19 absorbs the assigned reagent from the inside of a reagent cup 15. The reagent is dispensed by the prescribed nozzle of the nozzle part 19 into the reaction tube to be dispensed with the 1st reagent when said reaction tube arrives at the 1st reagent dispensing position. On the other hand, the 2nd nozzle part 20 sucks the 2nd reagent from the inside of a cup 15 in the 2nd turntable 16b into the corresponding nozzle by the operation similar to the operation of the part 19. This reagent is dispensed into the corresponding reaction tube in the 2nd reagent dispensing position. The nozzle parts 19, 20 move respectively to nozzle cleaning tanks 24a, 24b, upon completion of the dispensing, where the inside and outside walls of the nozzles are washed. The table part 14 is thus made smaller in size and the high-speed treatment is made possible with the high accuracy. |
