The decanter centrifuge cannot separate biological solids with very small density differences, such as cells and viruses. [5] A competitive process that is capable of separating these difficult-to-separate solids is the tubular-bowl centrifuge. The machine can be very noisy and can cause vibration.
Density gradients for purifying cells are also run in these centrifuges. Swinging-bucket rotors tend to be used very widely because of the huge flexibility of sample size through the use of adaptors. [9] These machines have maximum rotor speeds of less than 10 000 rpm and vary from small, bench-top to large, floor-standing centrifuges. [11]
Decantation is a process for the separation of mixtures of immiscible liquids or of a liquid and a solid mixture such as a suspension. [1] The layer closer to the top of the container—the less dense of the two liquids, or the liquid from which the precipitate or sediment has settled out—is poured off, leaving denser liquid or the solid behind.
Large centrifuges are used to simulate high gravity or acceleration environments (for example, high-G training for test pilots). Medium-sized centrifuges are used in washing machines and at some swimming pools to draw water out of fabrics. Gas centrifuges are used for isotope separation, such as to enrich nuclear fuel for fissile isotopes.
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.
Decantation is a process of pouring off the top layer of liquid from a bottom layer of liquid or solid; Decanter centrifuge; Dropping funnels are similar in shape and design, and may be used as separatory funnels. They have standard taper ground glass joints at the stem.
Counter Current Decantation (CCD) is used in some facilities to extract water, totally clear of Uranium. Exchange current decantation depicted in centrifugal extractors as 1st stage. Zippe-type centrifuges use countercurrent multiplication between rising and falling convection currents to reduce the number of stages needed in a cascade.
Disc stack centrifuge is also useful in producing biodiesel, as an initiative to alternative energy sources. The centrifuge separates fuel from methanol or water to convert oils from raw materials (such as rape seed) into diesel fuel. Oil additives is used to improve fuel performances, and in order to remove as much contaminants as possible ...
