  • Patent number: 10101346
    Abstract: In accordance with embodiments, a transport mechanism transports a first sample container to a sample aspiration position. A setting part may set a second sample container, that accommodates a sample to be measured, with priority over a measurement of a sample in a first sample container. A nozzle may be capable of moving a sample from a first sample container at a sample aspiration position, and aspirating the sample from the second sample container. A detector may detect components of the sample. A controller may control a transport mechanism such that the first sample container moves to a position distant from the sample aspiration position, when the first sample container has been transported and when sample aspiration of the second sample container is required. A controller may execute control to move the nozzle above the sample aspiration position in state in which the first sample container is distant from the sample aspiration position.
