去するようにしている。In such a cleaning tank, when the dispensing nozzle is washed several times, contaminants float in the cleaning liquid stored in the first cleaning liquid storage recess and the second cleaning liquid storage recess. Can adversely affect the results of sample analysis. Therefore, conventionally, a first cleaning liquid supply nozzle and a second cleaning liquid supply nozzle are provided in a cleaning tank, and the cleaning liquid is supplied from these cleaning liquid supply nozzles to the first cleaning liquid storage concave portion and the second cleaning liquid storage concave portion. The first cleaning liquid and the second cleaning liquid overflow from the cleaning liquid storage concave portion and the second cleaning liquid storing concave portion to remove contaminants.

For example, when the first cleaning liquid overflowing from the first cleaning liquid storage recess flows into the second cleaning liquid storage recess,
There is a possibility that the second cleaning liquid stored in the cleaning liquid storage recessed portion is contaminated by the first cleaning liquid. On the other hand, if the first cleaning liquid storage concave portion and the second cleaning liquid storage concave portion are separated from each other and separated as appropriate, not only the cleaning liquid becomes large and the cleaning efficiency decreases, but also the first cleaning liquid storage concave portion becomes large. During the transfer from the recess to the second cleaning liquid storage recess, the remaining liquid during cleaning spills and contaminates the main body of the analyzer, and the deposited components in the first cleaning liquid clog the drainage line after overflow. Can also occur.

The first cleaning liquid storage recess 21
The first cleaning liquid overflowing from the second cleaning liquid does not flow into the second cleaning liquid storage recess 22. As a result, the overflow liquid from the first cleaning liquid storage concave portion 22 and the second cleaning liquid storage concave portion 23 does not flow into other than the overflow liquid recovery concave portion 27, and the first liquid due to the overflow liquid does not flow.
The contamination of the cleaning liquid and the second cleaning liquid can be prevented. In particular, regarding the cleaning of the reagent dispensing nozzle 10, since the second cleaning liquid is a cleaning liquid having a diluting action, such as pure water or ion-exchanged water, the first and third cleaning liquids interfere with each other and the cleaning effect is obtained. There is no risk of offsetting. Also,
In the overflow liquid recovery unit 27, the precipitated components in the acidic detergent are dissolved by water (washing tank 11), or the alkali and the acid are neutralized (washing tank 12).
There is no problem such as clogging or corrosion of the discharge nozzle 28.
