container 22 is suctioned specifically after one syringe unit 12 positioned above one sample container 22 is lowered and the sample is suctioned this syringe unit 12 is raised thereafter the arm 11 of the dispensing mechanism 10 is moved in the y axis direction by the transfer unit 70 to position the other syringe unit 12 above the same sample container 22 then after this other syringe unit 12 is lowered and has suctioned the sample from the same sample container 22 this other syringe unit 12 is raised then after the arm 11 of the dispensing mechanism 10 is moved above the innermost reaction detection block 60 a by the transfer unit 70 the two syringe units 12 are lowered and the identical samples are discharged into two cells 66 a of the detection cell 65 in this case the arm 11 of the dispensing mechanism 10 is moved so as to not pass above the other second through fifth reaction detection blocks counting from the inside when sample is discharged into the two cells 66 a of the detection cell 65 the sample and enzyme reagent and primer reagent ck 19 and u03b2 actin accommodated in the two cells 66 a are mixed by multiple repetitions of the suction and discharge actions using the pump 12 b of the two syringe units 12 when dispensing the primer reagent enzyme reagent and sample the fluid temperature within the detection cell 65.
