The apparatus used for centrifugation is called a centrifuge. The centrifuge consists of a centrifuge tube holder called rotor. The rotor holds balanced centrifugal tubes of equal amounts of the solid-liquid mixture.

In analytical ultracentrifuges the maximum speed is 70000 rpm.

Cenrifugation technique can be used to isolate subcellular organelles of a cell suspension.

Centrifugation is a process which involves the use of the centrifugal force for the sedimentation of heterogeneous mixtures with a centrifuge used in industry and in laboratory settings. This process is used to separate two immiscible liquids.

The separation of cream from milk in the centrifugal separator is based on the fact that when liquids of different specific gravities revolve around the same centre at the same distance with the same angular velocity, a greater centrifugal force is exerted on the heavier liquid than on the lighter one. Milk can be regarded as two liquids of different specific gravities, the serum and the fat.

Centrifugation is a process which involves the use of the centrifugal force for the sedimentation of heterogeneous mixtures with a centrifuge, used in industry and in laboratory settings. This process is used to separate two immiscible liquids.
Uses:

• Separating chalk powder from the water.
  
• Removing fat from milk to produce skimmed milk.
  
• Separating water from textiles
  
• Removing water from lettuce after washing it in a salad spinner.
  
• Separating particles from an air-flow using cyclonic separation.
  
• The clarification and stabilization of wine.
  
• Separation of water particles from clothes while spin-drying in washing machines.
  
• Separation of urine components and blood components in forensic and research laboratory.
  

Centrifugation is a technique which involves the application of centrifugal force to separate particles from a solution according to their size, shape, density, the viscosity of the medium and rotor speed. The larger the size and the larger the density of the particles, the faster they separate from the mixture. Example- washing machine works on the principle of centrifugation.

Particle X and Y are having same size, shape and colour but they are having different masses, 

Centrifugation is a separation process which uses the action of centrifugal force to promote accelerated settling of particles in a solid-liquid mixture. Two distinct major phases are formed in the vessel during centrifugation .It is best method for separating of mixture have different masses for example removing of cream from milk.
