Abstract: A sampling apparatus 1 samples a culture medium in a bioreactor 11. A pump 21 circulates the culture medium in the bioreactor 11 via a flow path 41 by leading out the culture medium from the bioreactor 11 into the flow path 41 and introducing the culture medium from the flow path 41 into the bioreactor 11. A valve 22 is provided in the middle of the flow path 41, and switches a flow path such that the culture medium circulated in the flow path 41 flows out to a branch flow path 42 to be sampled.

Abstract: A dispensing apparatus that sucks and discharges liquid through a tip includes a motor, a tip attaching and detaching unit allowing attachment and detachment of a plurality of the tips, a tip holder that holds the plurality of tips, a support member that supports the tip attaching and detaching unit in a displaceable manner, and a drive transmitter that transmits a driving force of the motor to the support member. The drive transmitter includes a transmission switch that switches the drive transmitter from a transmission state in which the driving force of the motor is transmitted to a non-transmission state in which transmission of the driving force of the motor is blocked when an overload on the motor exceeds an upper limit value in a case where the plurality of tips held by the tip holder is attached to the tip attaching and detaching unit along with a displacement of a position of the tip attaching and detaching unit.

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.

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.
