ABSTRACT:
In a distributing device for sucking a desired amount of a sample liquid in a sample vessel and discharging the thus sucked sample liquid into a reaction vessel, a probe for sucking and discharging the liquid is connected to a syringe driven by a pulse motor. A photoelectric detector is provided for detecting whether the sample liquid is present or not up to a predetermined level in the sample vessel and an actual amount of the sample liquid aspirated by the syringe is detected by a counter which counts clock pulses during the aspirating operation. When the liquid level descends lower than the predetermined level, the counting operation is stopped. The actual amount of the aspirated liquid in the probe is compared with a desired amount stored in a memory. When the actual amount of the sucked liquid is smaller than the desired value, an alarm is produced.
