Key Points

  • Principle of Centrifugation​
    •  As per the principle, the denser particles are forced to the bottom and the lighter particles stay at the top when spun rapidly. Hence statement 1 is incorrect.
    • This principle is applied in diagnostic laboratories for blood and urine tests. Hence statement 2 is correct.
    • This principle is applied in dairies and in homes to separate butter from cream. Hence statement 3 is correct.

​Additional Information

  • Centrifugation is 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 a centrifuge tube.
    • The tube is then placed in a rotor and spun at a defined speed.
