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.
In centrifugation the clearing factor or k factor represents the relative pelleting efficiency of a given centrifuge rotor at maximum rotation speed. It can be used to estimate the time t {\displaystyle t} (in hours) required for sedimentation of a fraction with a known sedimentation coefficient s {\displaystyle s} (in svedbergs ):
High-speed or superspeed centrifuges can handle larger sample volumes, from a few tens of millilitres to several litres. Additionally, larger centrifuges can also reach higher angular velocities (around 30,000 rpm). The rotors may come with different adapters to hold various sizes of test tubes, bottles, or microtiter plates.
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 ...
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.

The sedimentation coefficient is typically dependent on the concentration of the solute (i.e. a macromolecular solute such as a protein). Despite 80+ years of study, there is not yet a consensus on the way to perfectly model this relationship while also taking into account all possible non-ideal terms to account for the diverse possible sizes, shapes, and densities of molecular solutes. [2]
A tricanter centrifuge operates on a similar principle to decanter centrifuges but instead separates three phases, consisting of a suspended solids phase and two immiscible liquids. [5] Sedimentation of the suspended solids occurs as normal where they accumulate on the wall of the bowl and are conveyed out of the centrifuge.
