Centrifuge HT20MM Basic principle
When the suspension containing fine particles stands 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 a gravitational field is
related to the size, shape and density of the particles, and is
also related to the strength of the gravitational field and the
viscosity of the liquid. Particles the size of red blood cells with
a diameter of a few microns can be observed under normal gravity.
In addition, when the substance settles in the medium, there is
also a diffusion phenomenon. Diffusion is unconditional and
absolute. 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
move under external forces. The sedimentation is proportional to
the weight of the object, the larger the particle, the faster the
sedimentation. For particles smaller than a few microns, such as
viruses or proteins, they form a colloidal or semi-colloid state in
the solution, and 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
the use of the strong centrifugal force generated by the high-speed
rotation of the centrifuge rotor to accelerate the sedimentation
speed of particles in the liquid, and separate substances with
different sedimentation coefficients and buoyancy densities in the
sample
