Centrifugationis a technique used for the separation of particles from a solution according to their size, shape, density, viscosity of the medium and rotor speed.
The particles are suspended in a liquid medium and placed in acentrifuge tube.The tube is then placed in arotorand spun at a define speed.
Separation through sedimentation could be done naturally with the earth gravity, nevertheless, it would take ages.Centrifugationis making that natural process much faster.
Rotation of the rotor about a central axis generates acentrifugal forceupon the particles in the suspension.
