Abstract

PURPOSE:To make separate injection of high precision possible for a long period by eliminating unneeded operations of cylinders arranged on a support board in parallel by selectively driving pistons of cylinders by an operation member via individual ganging mechanisms which are put to work by an external command. CONSTITUTION:Several cylinders 1 are arranged on support board 2 in parallel and change-over valves 6 are provided to suction-discharge parts 1a of respective cylinders 1 and changed over by the same driving member at once. One change-over mouth part 6a is piped to reagent container 9 via pipe 7 and the other change-over mouth part 6b is to sample container 12 via pipe 10. Piston 1b of each cylinder 1 is driven by press board 26 through the vertical movement of sliding member 23 engaged with worm 19 rotated by the motor. Between press board 26 and the lower end of piston 1b, ganging board 27 is provided which can be ganged and detached by the solenoid mechanism, and an external command gangs the board with piston 1b of a desired cylinder via the solenoid to drive piston 1b, thereby performing separate injection.
