Centrifugation: Theory, Sedimentation Rate, Coefficient ...

The instantaneous sedimentation rate of a particle during centrifugation is determined by three forces: (1) F C, the centrifugal force, (2) F B, the buoyant force of the medium, and (3) F F, the frictional resistance to the particle's movement.. Equation 12-13 is very important to the understanding of particle sedimentation and should be carefully examined, for the equation shows that ...

The centrifuge is composed of a rotor, which is used to house the tubes where separation occurs. There are two main types of centrifuge rotors: fixed-angle or swinging bucket. Fixed-angle rotors hold tubes at a stable angle (typically 45°) relative to the axis of rotation. A swinging-bucket rotor swings out when centripetal force is applied ...

How a Centrifuge Works - Drucker Diagnostics

A centrifuge is a machine that uses centrifugal force to separate the contents of a sample based on their density. When the centrifuge spins, it creates a strong centrifugal force. Though separation would eventually happen naturally with Earth's gravity, the centrifuge machine delivers rapid results for laboratory and other applications.

Centrifuge - Wikipedia

A centrifuge is a device that uses centrifugal force to separate various components of a fluid. This is achieved by spinning the fluid at high speed within a container, thereby separating fluids of different densities (e.g. cream from milk) or liquids from solids. It works by causing denser substances and particles to move outward in the radial direction.
