える。As described above, the powdery and granular sample dispenser according to the present invention is provided with a powdery material filled in the measuring part by protruding and retracting the measuring part for quantitatively holding the particulate material sample by a sliding action. The quantitative sample can be easily dispensed without spilling the granular sample into the reaction vessel. In addition, the provision of the hopper enables continuous distribution of the powder sample. Further, by providing the funnel, the scattering of the powder sample at the time of the distribution operation can be prevented. In addition, by arranging a plurality of measuring units in parallel, distribution to a multi-row / multi-row reaction vessel can be performed efficiently.
