PURPOSE:To improve the capacity of analytical treatment without increasing the area of a reaction line by making the reaction line have a double-circle structure of an inside reaction line and an outside reaction line and by driving these lines independently of each other. CONSTITUTION:For instance, seventy-five reaction vessels 12 are disposed on an outside reaction line 15B. The number inside each reaction vessel 12 is a position number. The reaction vessels 12 are disposed likewise on an inside reaction line 15A, but the number thereof is smaller than seventy-five. Between the inside reaction line 15A and the outside reaction line 15B at desired positions in the peripheral edge of a reaction bath 11, magnets 13 for B/F separation are disposed, and a photometric unit 14 measuring the amount of antigen by subjecting a reaction liquid in each reaction vessel 12 to photometry is disposed. CPU 16 controls the inside reaction line 15A and the outside reaction line 15B constructing a reaction line 15 and first and second driving sources 21 and 22 and makes them execute analytical treatment at a prescribe cycle time. According to this constitution, the capacity of the analytical treatment for immunity can be improved. |
