  • Publication number: 20210292698
    Abstract: A stirring device 11 includes a stirring mechanism 7 and a control unit 15. The stirring mechanism 7 includes a motor 74 and a pedestal portion 77. In the stirring device 11, the motor 74 repeats forward rotation and reverse rotation alternately under the control of the control unit 15. Then, the pedestal portion 77 repeats turning in one direction and turning in the other direction alternately. As a result, the test tube S repeats the movement in one direction and the movement in the other direction alternately, and the vortex rotating in one direction and the vortex rotating in the other direction are alternately generated in the mixed solution in the test tube S. Then, the mixed solution in the test tube S is stirred to be rotated, and is stirred to be moved in the vertical direction. Therefore, the mixed solution in the test tube S can be efficiently stirred. As a result, the time required for stirring the mixed solution in the test tube S can be shortened.

  • Publication number: 20210292705
    Abstract: When a stirring device 11 performs processing of stirring a mixed solution in a test tube S, a holding mechanism 13 and a movement mechanism 14 are operated so that the test tube S is moved to a position of B2. 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 152. 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 device 11 can be improved.
