Abstract: A sample analyzer that includes a sample preparing section operative to aspirate a sample from a sample container and a measuring section operative to prepare a plurality of measurement samples from the aspirated sample. A control unit is configured to sequentially measure the plurality of prepared measurement samples, obtain a plurality of measurement data for the respective measurement samples, and obtain an analysis result of a predetermined item of the sample based on the plurality of measurement data.

Abstract: A sample analyzer includes a liquid aspirator to be stuck into the closed container for aspirating a sample from a closed container; a preparing section for preparing an analysis sample using the aspirated sample; and an analyzing section for analyzing the prepared analysis sample; the liquid aspirator including an elongated pipe, the pipe having a liquid flow path extending therein and a plurality of communicating sections provided in an outer surface thereof, at least one of the communicating sections communicating between an inside and an outside of the container when the pipe is stuck into the container.

Abstract: Liquid aspirators are described that include an aspirating pipette; a drive source for descending the aspirating pipette; and a controller for controlling the drive source; the aspirating pipette being stopped from being descended by loss of synchronism of the drive source caused by upward force to be exerted on the aspirating pipette. Analyzers are also described.
