PURPOSE:To permit multinominal inspection of reagent always under the same conditions by connecting a multitubular nozzle having branch parts to a valve, connecting the other end of the valve to a suction pump and sucking the reagents into the respective branch parts. CONSTITUTION:The multitubular nozzles 2, 3 are inserted into a vessel 1 for supplying an objective liquid and a selector valve 4 is held open to both branch pipes 3b, 3c so that the objective liquid L is sucked by a syringe pump 5. The liquid L passed through a common suction part 2 and a base part pipe 3a and is sucked in approximately the same amt. into the two branch pipes 3b, 3c. The differences in inspection accuracy are eliminated between the liquids Lb and Lc and between the liquid in the upper position in the pipes 3b, 3c and the liquid in the lower position thereof if the liquid L is sucked to about the level at which the liquids Lb, Lc in the pipes 3b, 3c to not generate a concn. gradient. The good measurement accuracy is thus obtd. for all inspection items by adequately selecting the amt. of the objective liquid necessary for all the inspection items and the number of the branch pipes. |
