PURPOSE:To rapidly dispense plural reagents without the possibility of contamination with each other by installing dispensers respectively separately to plural pieces of reagent vessels which store the different reagents and are disposed on the same circumference. CONSTITUTION:A reaction vessel is transferred into and stopped at a reagent dispensing position where plural dispensing ports are provided. An operation lever 19 for driving the dispensers 1 of the reagent vessels 9 to discharge the reagents into the reaction vessel is then swiveled by a pulse motor 26 to select the required reagent 10 from the plural vessels 9 and is stopped right above the same. The lever 19 is then moved downward by a vertically moving mechanism (a pulse motor 32, pinion 31, a rack 30, a stopper 29, and a spring 27) to push down the plunger 6 of the dispenser 1, by which the reagent 10 is dispensed from a discharge port 17 through a flow pipe 18 into the reaction vessel from a dispensing port. The lever 19 moves upward to be reset to the initial position thereafter. The lever 19 is in succession subjected to the next swiveling and the downward movement by which the 2nd reagent 10 is dispensed. Since the pipes 18 of the respective reagents 10 are independent, the contamination of the reagents with each other does not arise. |
