PHARMA long-term-use industrial centrifuge machine China for pharmaceutical

Centrifugation is to use the strong centrifugal force generated by the high-speed rotation of the centrifuge rotor to speed up the settling velocity of particles in the liquid and separate the materials with different settling coefficient and buoyancy density in the sample.
When the suspension containing fine particles stands still, the suspended particles gradually sink due to the action of gravity field.
The heavier the particle, the faster it sinks, whereas particles less dense than the liquid rise.
The speed at which a particle moves in a gravitational field is related to the size, shape, and density of the particle, as well as to the strength of the gravitational field and the viscosity of the liquid.
Particles the size of red blood cells, measured in microns across, can be observed settling under normal gravity.
In addition, the matter in the medium settlement also accompanied by diffusion phenomenon.
Diffusion is unconditional and absolute.
Diffusion is inversely proportional to the mass of the material, the smaller the particle, the more serious the diffusion.
The settlement is relative, conditional, to be subject to external forces to move.
The settlement is proportional to the weight of the object, and the larger the particle, the faster the settlement.
For particles smaller than a few microns, such as viruses or proteins, which form colloids or semi-colloids in solution, the deposition process cannot be observed by gravity alone.
The smaller the particle, the slower the sedimentation and the more serious the diffusion.
Therefore, it is necessary to use a centrifuge to generate a strong centrifugal force, in order to force these particles to overcome the diffusion and produce settling motion.
