In the chemical and food industries, special centrifuges can process a continuous stream of particle turning into separated liquid like plasma. Centrifugation is also the most common method used for uranium enrichment , relying on the slight mass difference between atoms of U-238 and U-235 in uranium hexafluoride gas.
A centrifuge can be a very effective filter that separates contaminants from the main body of fluid. Industrial scale centrifuges are commonly used in manufacturing and waste processing to sediment suspended solids, or to separate immiscible liquids. An example is the cream separator found in dairies.
A decanter centrifuge applies a force equivalent to several thousand G's, which reduces the settling time of the particles. It is also favoured to maintain a large G-force, which will result in an improved separation. [8] The rate at which sedimentation occurs is an important characteristic of the decanter centrifuge separation process.
A laboratory ultracentrifuge. In chemistry, a Svedberg unit or svedberg (symbol S, sometimes Sv [a]) is a non-SI metric unit for sedimentation coefficients.The Svedberg unit offers a measure of a particle's size indirectly based on its sedimentation rate under acceleration (i.e. how fast a particle of given size and shape settles out of suspension). [1]
Differential centrifugation. In biochemistry and cell biology, differential centrifugation (also known as differential velocity centrifugation) is a common procedure used to separate organelles and other sub-cellular particles based on their sedimentation rate.
Rate-zonal centrifugation is a centrifugation technique employed to effectively separate particles of different sizes. [1] The tube is first filled with different concentrations of sucrose or another solute establishing layers with different densities and viscosities , forming a density gradient , within which the particles to be separated are ...
A laboratory centrifuge is a piece of laboratory equipment, driven by a motor, which spins liquid samples at high speed. There are various types of centrifuges, depending on the size and the sample capacity.
An ultracentrifuge is a centrifuge optimized for spinning a rotor at very high speeds, capable of generating acceleration as high as 1 000 000 g (approx. 9 800 km/s²). [1] There are two kinds of ultracentrifuges, the preparative and the analytical ultracentrifuge.
