PURPOSE:To decrease pumping mechanisms for dispensing considerably by connecting plural reagent discharge ports and flow passage selectors, connecting reagent containing vessels in the midways of connecting flow passages and performing suction and discharge of reagents in parallel with the suction and discharge operations of a washing liquid supplying device. CONSTITUTION:Selector valves 20a-20d for flow passages for reagents are changed over to the broken line sides and sliding valves 35, 36 are positioned successively to V1-V4 to effect suction operation whereby reagent liquids are sucked into retreated reagent tubes 26a-26d. Thereafter, the valves 20a-20d are changed over to the solid line positions and the sliding valves are positioned successively to V5-V8. In the respective positions, syringes 23 are operated to perform discharging by each prescribed stroke so that the reagent liquids corresponding to respective analyzing items are added to respectively corresponding reacting vessels 3a-3d through the discharge ports of nozzles 11a-11d. Thus, a reagent adding mechanism is constituted with a small number of the syringes and the reduction in the size of the analyzing device is made possible. |
