PURPOSE:To provide flexibility to a timing for dispensing a reagent and to dispense the reagent at an optimum timing by rotating a rotary disk to again rotate and move the reaction tube in an optional position where the dispensing of the reagent, etc., by a dispensing means is executed to the position of the dispensing means. CONSTITUTION:The rotary disk 14 and dispensing means 3, etc., are provided. The rotary disk 14 rotates one turn and as much as a piece of the reaction tube intermittently in 1min for one cycle. A sample and reagent are respectively dispensed into the reaction tubes existing in the sample position S1 and reagent dispensing position S2 during the stoppage of the rotary disk. The reaction tube in the optional position subjected already to dispensing of the sample and reagent by the dispensing means 3 is stopped again at the reagent dispensing position S2 of the means 3 in the midway of the movement for one step by rotating the rotary disk 14 when the dispensing as well as cleaning and drying are not executed. The rotary disk 14 is again rotated to return the reaction tube to the original position after the movement by one step upon dispensing of the reagent by which the flexibility is provided to the timing for the 2nd and subsequent dispensing of the reagent. |
