WebSeparators are centrifuges for liquid–liquid separation, for liquid–liquid solid separation or for liquid–solid separation. They have tubular discs or angular chamber bowls. Separators operate continuously in terms of discharges of the liquid phase. In respect of the solid discharge, they work either discontinuously (i.e. discontinuous disc-type centrifuges, … Protocols for centrifugation typically specify the amount of acceleration to be applied to the sample, rather than specifying a rotational speed such as revolutions per minute. This distinction is important because two rotors with different diameters running at the same rotational speed will subject samples to … Ver mais A centrifuge is a device that uses centrifugal force to subject a specimen to a specified constant force, for example to separate various components of a fluid. This is achieved by spinning the fluid at high speed within a … Ver mais English military engineer Benjamin Robins (1707–1751) invented a whirling arm apparatus to determine drag.
