Centrifugation is the use of the powerful centrifugal force generated by the high-speed rotation of the centrifuge rotor to accelerate the sedimentation velocity of the particles in the liquid, and separate the sedimentation coefficient and the buoyant density of the sample.Therefore, it is necessary to use a centrifugal machine to generate a strong centrifugal force in order to force these particles to overcome the diffusion to produce a settling motion. The centrifuge has a cylinder that rotates at a high speed about its own axis, called a drum, which is usually driven by an electric motor. After the suspension (or emulsion) is added to the drum, it is rapidly driven to rotate at the same speed as the drum, and the components are separated under the action of centrifugal force and discharged separately.Generally, the higher the drum speed, the better the separation effect. Centrifugation is to use the powerful centrifugal force generated by the high-speed rotation of the rotor of the centrifuge to accelerate the settling speed of particles in the liquid and separate the materials with different settling coefficients and buoyancy density in the sample. Centrifuges are widely used in chemical, petroleum, food, pharmaceutical, mineral processing, coal, water treatment and shipping sectors.
