Abstract
It is possible to maintain, in clean condition, a solenoid valve for discharge of cleaning fluid accumulated in a vacuum bottle in which the cleaning fluid adhering to a probe collects. An automatic analyzer includes: a cleaning bath that has a cleaning fluid outlet from which cleaning fluid is discharged for cleaning a probe, and a vacuum suction port into which the probe is inserted; a cleaning tank that stores the cleaning fluid; a vacuum tank; a vacuum pump that causes the vacuum tank to be placed under negative pressure with respect to atmospheric pressure; a vacuum bottle placed between the vacuum suction port and the vacuum tank; and, as channels through which the cleaning fluid flows into the vacuum bottle, a first channel connected to the vacuum suction port and a second channel connected to the cleaning tank.
