Abstract: A sample analyzer comprises a container setting part on which a liquid container is to be set, a liquid supplying part configured to supply a liquid to the liquid container, an aspiration tube configured to aspirate a sample or a reagent, a movement mechanism configured to move the aspiration tube, a liquid surface sensor configured to detect contact of the aspiration tube with a liquid surface, and a controller configured to execute an aspiration tube adjustment operation. The aspiration tube adjustment operation comprises supplying the liquid to the liquid container by the liquid supplying part, lowering the aspiration tube by the movement mechanism toward the liquid container set on the container setting part, and obtaining information regarding a position in a height direction of the aspiration tube at a time when the aspiration tube has come into contact with the liquid surface.
