PURPOSE:To prevent the wasteful consumption of a specimen by shortening a specimen suction pipe, by linearly arranging the specimen suction pipe by making a measuring part and an automatic sampler relatively movable in an up-and- down direction. CONSTITUTION:A motor 2 is rotated and light measuring apparatus 1 and a specimen suction pipe 1e are integrally fallen by a screw lever 3. When the suction pipe 1e is immersed in a specimen container 7 and a liquid level is detected by a liquid level detector, the motor 2 is stopped and a pump 5 is operated to suck the specimen into a flow cell 1c from the suction pipe 1e. At the point of time when suction is finished, the motor 2 is rotated reversely to draw up the suction pipe 1e and a sample holder 6b is rotated by one step and the next specimen container is moved to the position under the suction pipe 1e. |
