Antonin Prandtl, an 1864 inventor of the dairy centrifuge that separates cream from milk, proposed the idea. Gas centrifuges can be used to separate isotopes, such as enriching nuclear fuel for fissile elements.īenjamin Robins (1707-1751), an English military engineer, invented a whirling-arm apparatus to measure drag. For the extraction of water from fabrics, medium-sized centrifuges can be found in washing machines as well as at swimming pools. For example, large centrifuges can be used to simulate high acceleration or gravity environments (for pilot training). Ultracentrifuges and high-speed centrifuges that can provide high accelerations are capable of separating fine particles down to the nanoscale and molecules with different masses. One example of this is the cream separator used in dairy plants. In manufacturing and waste treatment, industrial centrifuges are used to remove suspended solids or separate immiscible fluids. A centrifuge is a powerful filter that can separate contaminants from main fluid. A laboratory centrifuge using sample tubes causes the radial acceleration to cause denser particles settle to the bottom of a tube while lower-density substances rise up to the top. Conversely, objects with a lower density are displaced and moved to the centre. It causes particles and substances that are denser to move in the radial direction. It can then separate fluids with different densities (e.g. This is done by spinning fluid at high speeds within a container. A centrifuge uses centrifugal force in order to separate different components from a fluid.
