What is the centrifugation principle of the large capacity refrigerated centrifuge?

When a suspension containing fine particles is left still, the suspended particles gradually sink due to the action of the gravity field. The heavier the particle, the faster it sinks, otherwise the particle with a density lower than that of the liquid will float up. The speed of particles moving in the gravity field is related to the size, shape and density of the particles, and also related to the strength of the gravity field and the viscosity of the liquid. Particles the size of red blood cells, with a diameter of several microns, can be observed under normal gravity.

In addition, when a substance settles in a medium, it is accompanied by a diffusion phenomenon. Diffusion is unconditional. Diffusion is inversely proportional to the mass of the substance, the smaller the particle, the more serious the diffusion. The settlement is relative, conditional, and can only be moved by external forces. The settlement is proportional to the weight of the object, the larger the particle, the faster the settlement. For particles smaller than a few microns, such as viruses or proteins, they form a colloidal or semi-colloid state in the solution. It is impossible to observe the sedimentation process only by gravity. Because the smaller the particles, the slower the sedimentation, and the more serious the diffusion phenomenon. Therefore, it is necessary to use a centrifuge to generate a strong centrifugal force to force these particles to overcome diffusion and produce a settling motion.

Centrifugation is to use the powerful centrifugal force generated by the high-speed rotation of the centrifuge rotor to accelerate the sedimentation speed of the particles in the liquid and separate the substances with different sedimentation coefficients and buoyancy densities in the sample.
