When a stirring deviceperforms processing of stirring a mixed solution in a test tube S, a holding mechanismand a movement mechanismare operated so that the test tube S is moved to a position of B. Then, in the test tube S, the cells attached to the inner surface of the test tube S and the liquid are separated. Further, the cells attached to the inner surface of the test tube S are detected by a color sensor. Therefore, it is possible to reduce the work for determining the end of the stirring processing by the user. As a result, the workability of the user when using the stirring devicecan be improved.
