PURPOSE:To continuously perform the distribution of a specimen, by performing the washing of a reaction tube by recirculating and passing the same through the same washing apparatus during the analysis of each specimen by recirculating and passing the reaction tube through the washing apparatus provided to a reaction line constituted in an endless form during the analysis of each specimen while continuously distributing the specimen. CONSTITUTION:In the first rotation of a reaction tue disc 12, one carrier 23 from a carrier throw-in apparatus 22 is thrown in the U-shaped tube 11 positioned at a stop position S1 from the large opening part 11a of said tube 11. At this stop position S1, a predetermined amount of a first reagent 17 comprising a buffer solution is simultaneously distributed in the tube 11 by a first reagent distributing apparatus 16. After the reaction tube 11 is sent over by three pitches, a predetermined amount of a specimen is distributed in the tube 11 at a position S4 by a specimen distributing apparatus 13. By this procedure, antigen-antibody reaction is started. The reaction tube reaches a stop position S25 at the last stage of the first rotation and washing is performed by a washing apparatus 26 while a first time B.F separation is performed. In the next step, the reaction tube disc 12 enters a second rotation and, at a stop position S3, second reaction is started. At the final stop position S25 of the second rotation, second B.F separation is performed by a washing apparatus 25. |
