Centrifugation Principles

Principles of Centrifugation. Many principles govern the mechanics of centrifugation, but the primary is centrifugal force. Centrifugal force is an outward push experienced during high-speed rotation, acting radially from the center of rotation and causing the movement and sedimentation of particles suspended in a sample.

Applications of Centrifugation

A few important applications of centrifugation are listed below. ... What is the principle of centrifugation? The technique of centrifugation operates using the concept of sedimentation, where the centrifugal force causes denser liquids and particles to travel in the radial direction outwards. Around the same time, objects with relatively low ...

Introduction: Principles and Practices of Centrifugation

 — It is also important to contain the sample during centrifugation, particularly as the samples are often biohazardous or radioactive. Also, the rotors of all ultracentrifuges run in a high vacuum to minimize heating due to air resistance and so it is especially important to isolate the sample, to prevent evaporation, by capping the tubes securely.

8 Types of Centrifugation with Principles and Uses

  1. In a solution, particles whose density is higher than that of the solvent sink (sediment), and particles that are lighter than it floats to the top.
  2. The greater the difference in density, the faster they move. If there is no difference in density (isopycnic conditions), the particles stay steady.
  3. To take advantage of even tiny differences in density to separate various particles in a soluti…

  2. The greater the difference in density, the faster they move. If there is no difference in density (isopycnic conditions), the particles stay steady.
  3. To take advantage of even tiny differences in density to separate various particles in a solution, gravity can be replaced with the much more powerful "centrifugal force" provided by a centrifuge.
  4. A centrifuge is a piece of equipment that puts an object in rotation around a fixed axis (spins it in a circle), applying a potentially strong force perpendicular to the axis of spin (outward).
