Abstract:
1. An automatic analyzer comprising: an optical detector for analyzing a sample in a reaction cuvette; a plurality of said sample probes, each said sample probe including a sample probe head having a sample nozzle for dispensing a sample, each said sample probe including a liquid level detecting means detecting a surface level of a liquid, each of said sample probes moving from a sample suction position to a sample discharging position along a different moving path; a plurality of reaction cuvettes into which samples are dispensed by said sample probes and in which a reaction takes place followed by analysis with said optical detector; a plurality of washing ports for washing each of said sample probes, each of said washing ports being arranged along each of said moving paths, a controller for controlling said sample probes to reciprocally move between a single sample container containing sample at said sample suction position and a reaction cuvette at said sample discharge position to receive said sample alternately so as to prevent said sample probes from colliding with each other; and said controller controls one of said sample probes to detect a surface level of said sample in one said sample container, and said controller controls the sample dispensing operations of the other said sample probe on the basis of the information regarding said surface level of said sample in said one sample container.
