Ultracentrifuge is generally used in the field of biology and chemistry, and is a device for extracting, separating and purifying substances. The ultracentrifuge comprises a refrigeration system for reducing the temperature of the rotor and the sample to meet the use requirements. The refrigeration system of the existing ultracentrifuge adopts a refrigeration compressor scheme, and refrigeration is realized through the refrigeration compressor. But the ultracentrifuge adopting the compressor for refrigeration has the advantages that the ultracentrifuge with complex structure and large noise is a part suitable for the centrifugal machine, and the centrifugal box is required to be used when the centrifugal machine is used, and the centrifugal box rotates at the inner part of the centrifugal machine in an overspeed mode and works together with the centrifugal machine.

The container is arranged in the ultracentrifugation box, and is generally a plastic centrifuge tube, and the plastic centrifuge tube has the advantages of transparency or translucency, small hardness and capability of taking out gradients by a puncture method. The defect is easy deformation, poor resistance to organic solvent corrosion and short service life. Plastic centrifuge tubes all have tube covers which function to prevent leakage of the sample, which is important especially when used with radioactive or highly corrosive samples; the tube cap also has the function of preventing sample volatilization and supporting the centrifuge tube and preventing the centrifuge tube from deforming. When choosing this, care should be taken to check if the tube is tightly capped, and if it is tight, to reach an inverted leak-free condition.

However, in the actual use process of the device, the two centrifugal boxes cannot be fixed together, the two centrifugal boxes are inconvenient to fix and place, the traditional centrifugal box fixing mode is troublesome and is not beneficial to efficient work, and finally, the cost performance of the centrifugal box is low, and the use mode is time-consuming and labor-consuming; in view of this, we propose an ultracentrifugation cassette with dust-proof function.
