China Centrifuges are one of the most important chemistry lab equipments. They are simple devices usually driven by a motor that woks on the principle of sedimentation. Objects in a centrifuge is rotated around a fixed axis, thus applying a force perpendicular to the axis. The sedimentation principle uses the centripetal acceleration to evenly separate substances of varying density.

A large range of China centrifuges are available in market today. Some of them are very generic while some are highly specific. Centrifuges can be divided or categorized on several basis.

Usually the China centrifuges can be divided in two main categories. They are stationary centrifuges and rotating centrifuges. However both types work on the same principle. Particles of varying masses are set into motion around a common center. The faster the particles rotate, the greater will be the difference with which they separate from their common center, the easier they will be separated.

In the stationary types of China centrifuges, fluids(either gas or liquid) consisting of more than two components are injected at a high speed into a conical or cylindrical chamber. When the fluid moves around the sides of chamber, the components are separated. The heavier substances travel to the outer side while the lighter substances move closer to the center of the cylinder.

For the centrifuges used in laboratories, there are mainly two sizes. The bigger sized ones are simply known as centrifuges in which samples are contained in centrifuge tubes. Smaller laboratory China centrifuges are known as micro-centrifuges or microfuges and microfuge tubes are used foe containing sample.
