Background
The centrifugation is to accelerate the sedimentation velocity of particles in liquid by using the strong centrifugal force generated by the high-speed rotation of a centrifuge rotor, and separate substances with different sedimentation coefficients and buoyancy densities in a sample. The centrifugal working principle is as follows: when a suspension containing fine particles is left to stand still, the suspended particles gradually sink due to the action of the gravitational field. The heavier the particles, the faster they sink, whereas particles of lower density than the liquid will float up. The speed at which the particles move under the gravitational field is related to the size, morphology and density of the particles, and in turn to the strength of the gravitational field and the viscosity of the liquid.
