[0034] Working principle: When changing cell samples during cell separation using a cell centrifuge, a test tube containing the new cell sample can be fixed in the second rotor 9 beforehand. Then, by rotating the handle 3, the take-up reel 4 is rotated. When the take-up reel 4 rotates, the two steel wires 5 fixed on both sides are tightened. At this time, multiple pulleys 8 can assist the tightening of the steel wires 5. As the steel wires 5 tighten, the two clips 6 used to lock the rotor 9 are also pulled outward. At this time, the first rotor 9 inside the machine body 1 can be removed. Then, the second rotor 9 with the new test tube is pressed down into the empty slot of the machine body 1 and engages with the output end of the motor 22. Then, the handle 3 is released. At this time, the two clips 6 are pushed back to their original position by the two springs 7 fixed behind them to lock the second rotor 9. This achieves the effect of convenient and quick replacement of new cell test tubes, thus avoiding the problem of having to stop the cell centrifuge and replace the test tubes one by one, which leads to a long preparation time. The replaced rotor 9 is also easy to clean.

[0035] The centrifuge body 1 is fixed inside the noise reduction cabinet 201. The noise reduction cabinet 201 can reduce and isolate the noise generated during the operation of the cell centrifuge, and also prevent the test tubes from being contaminated by external factors. A rubber pad 202 is fixed around the body 1 to effectively absorb and alleviate the vibration generated during the operation of the cell centrifuge, thereby reducing the impact of the cell centrifuge on the surrounding environment. An observation window 203 is fixed in front of the noise reduction cabinet 201 to facilitate observation of the operation status of the cell centrifuge at any time. A pair of sterile gloves 204 is fixed in the middle of the observation window 203. Researchers can directly adjust the test tubes on the rotor 9 through the sterile gloves 204. The noise reduction cabinet 201 has a side door 206 on the right side that is opened and closed by two hinges 205 for inserting and removing test tubes from the cell centrifuge. This achieves the effect of reducing the noise and vibration of the cell centrifuge, and also reduces the probability of test tubes being contaminated by external factors.
