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.
More Details· The smaller the particle size, the higher the centrifugation speed. For example, bacterial cells are pelleted at higher speeds (2000–10,000 x g) than mammalian cells (500–2000 x g). Furthermore, lower centrifugation speeds may be used with more fragile samples. Another critical factor that influences the efficiency of separation is RCF.
More Details· A centrifuge is simply a machine that spins around to make a large and useful force. Small centrifuges are used in scientific laboratories (for example, to separate blood products). You can find much bigger ones in aerospace-labs, where they''re used for testing astronauts, pilots, and their equipment to absolute breaking point.

More DetailsBenjamin Arie Scientist placing a test tube in a centrifuge. A centrifuge is a device that spins an object or substance at high speed. This rotational motion generates centrifugal force on the substance in the centrifuge, which pulls particles away from the center of the device. Centrifuges are used in several types of applications, including laboratory experiments and industrial manufacturing.
More DetailsCentrifugation can also be used to separate emulsions (such as milk) and immiscible solvents (e.g., in combination with LLE). Laboratory centrifuges usually work with 20–40 cm diameter rotors holding 10–100 sample vials or two to four microtiter plates. Efficiency depends on rotational velocity; typical laboratory centrifuges work with 100 ...
