They are best used to separate materials that have similar densities; or when insoluble particulates are present in a dissolved solution. A common misconception is that a centrifuge employs a centrifugal force. In fact, all centrifuges work by utilising the sedimentation principle. The sedimentation principle is where the acceleration of the rotor causes a centripetal force to act upon the rotor and centrifuge tubes. This causes the denser substances in the tubes to be forced outward in a radial direction. This also causes the lighter particles to be displaced and move towards the centre. Many particulates can become 'stuck' at the bottom of centrifuge tubes, especially when using a laboratory centrifuge. These particles are commonly known as pellets, and the clarified solution is coined the supernatant. Although you will probably set a centrifuge to spin at revolutions per minute (rpm) or rotational speed, it is the acceleration that is the important factor. This is because two rotors could have different diameters but the same rotational speed. If this is the case the acceleration of the two rotors will not be the same. Because the acceleration is a product of the radius and the square of the angular momentum, the size of the rotor becomes a contributing factor. As a result, Relative Centrifugal Force (RCF) is used as a standard unit and is measured in terms of g. Centrifuge Applications Centrifuges can be used for a multitude of applications, because there are many different types available in today's market. Some common applications for centrifuges are listed below: Separation of mixtures with close densities Separate immiscible liquids Sediment suspended solids Separation of blood Separation insoluble particles (e.g. insoluble proteins in a protein solution) Isotope Separation Gravity simulation environments for astronauts Separating creams Washing machine spin function Separation of wastewater sludge Material synthesis in a high gravity environment #remir8cplus #remicentrifuge #R8cplus #centrifuge #Mannumlt #manojmlt #Manojmlt
