Abstract
Provided are a device and a cleaning mechanism for a reaction container in the device that are characterized by being provided with: a reaction disk for holding a reaction container; a sample dispensing mechanism for dispensing a sample to the reaction container; a reagent dispensing mechanism for dispensing a reagent to the reaction container; an optical system comprising a light source for applying light to a mixture of the sample and the reagent dispensed to the reaction container, and a detector for detecting the light applied from the light source; and a cleaning mechanism for cleaning the reaction container, wherein the cleaning mechanism is provided with a cleaning liquid supply nozzle for supplying a cleaning liquid to the reaction container after an analysis, a cleaning liquid suction nozzle for suctioning the supplied cleaning liquid, and a cleaning tip provided on the lower end of the cleaning liquid suction nozzle, and the side surface of the cleaning tip is formed such that the width of the cleaning tip becomes smaller downward, in the state where the cleaning tip is inserted into the reaction container, in at least a surface opposing the light source and a surface opposing the detector, and in a range that overlaps with a photometric range in which light applied to the reaction container from the light source passes through the reaction container toward the detector or in a range that is larger than the photometric range.
