PURPOSE:To enable discharge to accurate liquid measure within a certain time by controlling clinical examinations so that the exhaustion of a sample syringe will end before that of a diluent syringe. CONSTITUTION:Sample syringe 1 and diluent syringe 2, connected to each other via valve 3, have sample suction-exhaustion tube 5 which sucks and holds a liquid sample through the suction of syringe 1, and passage 25 which can suck a diluent from diluent tank 7 through the suction of syringe 2, so that the sample and diluent will be discharged from tube 5 through the exhaustion of syringes 1 and 2. In this case, driving part 11 of syringe 1 is so operated that the exhaustion of syringe 1 will end before that of syringe 2. |
