PROBLEM TO BE SOLVED: To accurately control the dispensing amount of specimen, prevent the non-uniformity of the absolute value of the dispensing amount and detect error, if found in the dispensing amount. SOLUTION: A prescribed capacity of share valve 10 is inserted in a specimen suction passage 6 and a specimen detecting means 15 is provided on at least one side thereof to detect specimen 18 passing through the share valve itself. In this way, judgement whether the capacity of specimen exists in the share valve 10 or not is made from whether the specimen 18 passing through the share valve 10 is detected or not. Only the specimen 18 in the share valve 10 can be dispensed as specimen. |
