Abstract:
An amount of gas remaining within a fluid control valve is reduced according to a method for fixing the fluid control valve to achieve highly accurate trace dispensation by simply removing gas. The dispensing device has a discharge nozzle, a liquid feeding tube that is disposed so as to connect a reagent bottle in which a reagent is stored and the discharge nozzle and forms a reagent flow path, and a fluid control valve that is disposed on the liquid feeding tube route connecting the reagent bottle and the discharge nozzle. The fluid control valve is provided with a reagent flow path having a liquid inlet and a liquid outlet and a diaphragm valve provided in the middle of the flow path. The fluid control valve is disposed in an orientation such that the diaphragm valve is disposed at the bottom of the flow path of the fluid control valve.
