Centrifugal Grading Machine

Product Details

Centrifugation is a method of separating molecules having different densities by spinning them in solution around an axis (in a centrifuge rotor) at high speed. It is one of the most useful and frequently employed techniques in the molecular biology laboratory.A centrifuge is a laboratory device that is used for the separation of fluids, gas or liquid, based on density. Separation is achieved by spinning a vessel containing material at high speed; the centrifugal force pushes heavier materials to the outside of the vessel.Some common examples of centrifugation include: The extraction of fat from milk in order to produce skimmed milk. The removal of water from moist lettuce with the help of a salad spinner. The Spin-drying of water in washing machines in order to remove water from the clothing.
