PURPOSE:To simplify the construction and its handling, by letting plural reaction lines on a pair of fixing tools and connecting a sample supply line and a flow passage in an analyzing system to said reaction lines. CONSTITUTION:A valve 1 consists of a moving central part 2 and a fixed part 3, 3 on both ends, and the two reaction line 4a, 4a and a general line 4b are provided in the part 2. The part 3, 3 of both bends of the valve 1 are provided with a sample supply line 7 and its end part is positioned in a buffer vessel 12. Further, the end part of a liquid discharging line 13 is positioned in a discharge liquid opening 15 and the end part of a washing water line 14 is positioned in a washing water vessel 17. In this manner, the construction and handling can be simplified, eliminating the need of action sucking the sample from a sample cup at every switching of the reaction line accompanied by dispensing. |
