PURPOSE:To enable the exact and simple mounting operation of dispensing nozzles for supplying reagents to plural reaction lines by varying the shapes of the dispensing nozzles and the shapes of nozzle mounting parts for each of the reaction lines. CONSTITUTION:The nozzle mounting parts 2A-2C and 3A-3C for 3 rows of the reaction lines A-C are formed to a dispensing nozzle mounting plate 1 which turns around a central axis O. The dispensing nozzles 4A-4C for dispensing the reagents are mounted to said parts. The nozzle mounting parts and the dispensing nozzles are formed to the shapes varying with the plural reaction lines A-C. For example, a star shape is adopted for the inside line A, a round shape for the intermediate line B and a square shape for the outside line C. The dispensing nozzles 4A-4C can, therefore, be exactly and easily mounted by each line and the dispensing errors of the reagents are eliminated. |
