If we assume a rotor diameter of 20 cm (as in some modern centrifuges [3]), this would correspond to a centripetal acceleration of around 900,000 x g [4] (around 42 times the max speed of a standard, lab benchtop microcentrifuge [5] and between 0.9 to 9 times the max speed of a standard lab ultracentrifuge [6]) or a linear speed of greater than ...
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.
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]
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.
