International Classification of Centrifuges and Their Roles

According to the speed classification: divided into low-speed centrifuges, high-speed centrifuges, ultra-centrifuges.

Low-speed centrifuge: The rotation speed is within 10,000 rpm or relative centrifugal force within 15000×g.

High-speed centrifuge: The rotation speed is within 10,000 ∽ 30000 rpm or the relative centrifugal force is within 15000 ∽ 70,000 × g.

Ultracentrifuge: Rotating speed above 30000 rpm or relative centrifugal force above 70,000 x g.

Classified by structure:

In general, high-speed and low-speed centrifuges are classified according to structure and function. There are many varieties and there is no uniform standard for each manufacturer. Can be divided into table-top centrifuges, multi-tube micro tabletop centrifuges, cell smear centrifuges, blood-washing tabletop centrifuges, high-speed refrigerated centrifuges, large-capacity low-speed refrigerated centrifuges, low-speed refrigerated centrifuges, bench-top high-speed refrigerated centrifuges, benchtops Low-speed automatic balance centrifuge. In addition, there are triple-type (five-joint) high-speed refrigerated centrifuges abroad, designed for continuous centrifugal use.

Centrifuges are machines that use centrifugal force to separate the components of a mixture of liquid and solid particles or liquid and liquid.

Centrifuges are mainly used to separate the solid particles in the suspension from the liquid; or to separate the two incompatible emulsions in the emulsion (for example, to separate cream from the milk); it can also be used to eliminate Liquids in wet solids, such as washing wet clothes with a washing machine; special overspeed tube separators can also separate gas mixtures of different densities; use different characteristics of solid particles of different densities or particle sizes in the liquid, some settlement Centrifuges can also classify solid particles by density or size.
