Abstract

A sample liquid-surface position measurement device includes: a first light source that illuminates a side face of a container containing a sample; a first optical measurement sensor that is located on the opposite side of the container from the first light source, and measures transmitted light from the first light source; a first label position measuring unit that measures a position of a label affixed to the container; and an analysis section that calculates a liquid-surface position or an interface position of the sample in the container, from transmitted-light intensity data in a longitudinal direction of the container which is measured by the first optical measurement sensor, and from the position of the label in the longitudinal direction of the container which is measured by the first label position measuring unit.
