[0002] In the study of agricultural gene cloning, gene extraction is a key step, which involves isolating DNA or RNA from plant or microbial samples. Centrifuge equipment is an important equipment in this process, which can separate different components in a mixture through the centrifugal force generated by high-speed rotation.

[0003] During the use of some existing centrifugal devices, the devices for placing test tubes are mostly fixed, so they cannot be used for test tubes of different specifications, nor can test tubes of different thicknesses be placed at the same time. As a result, test tubes of different thicknesses need to be separated separately, which is more troublesome. In addition, during the centrifugation process, some microbial samples have certain requirements on the output speed of the motor. The existing speed adjustment requires controlling the current input, so if the motor is run at overspeed for a long time, the internal parts of the motor may be damaged, thereby reducing the service life of the motor.
