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.

Centrifuge

1/7/2018, · A ,centrifuge, is a piece of equipment that puts an object in rotation around a fixed axis (spins it in a circle), applying a force perpendicular to the axis of spin (outward) that can be very strong. The ,centrifuge, works using the sedimentation principle, where the centrifugal acceleration causes denser substances and particles to move outward in the radial direction.

Centrifuges

"The ,Centrifuge, works on the principle of centrifugation, where the acceleration at centripetal force causes denser substances to separate out along the radial direction at the bottom of the tube. In a solution, particles which have higher density will sediment (Pellet) at the bottom and particles that are lighter will float to the top (Supernatant)".

centrifuge principle and application - SlideShare

The RCF value for any centrifuge may be calculated from the following equation: RCF = 1.18 × r × (rpm) 2 ×10-5 Where, 1.18×10-5 = An empirical factor r is the radius in cm from the centre of the centrifuge shaft to the external tip of centrifuge tube. rpm is the number of revolution per minute of the centrifuge rotor
