Centrifugation is to use the powerful centrifugal force produced by the high-speed rotation of the centrifuge rotor to speed up the settling speed of the particles in the liquid, and separate the materials with different sedimentation coefficient and buoyancy density in the sample. Therefore, it is necessary to use centrifuge to produce strong centrifugal force to force these particles to overcome the diffusion and produce sedimentation movement.

Centrifuge is the use of centrifugal force, the separation of liquid and solid particles or liquid and liquid mixture of components of the machinery. Centrifuges are mainly used to separate the solid particles in the suspension from the liquid; or to separate two kinds of liquid with different density and mutual immiscible in the emulsion (such as separating cream from milk); it can also be used to remove the liquid in the wet solid, such as drying wet clothes with a washing machine; the special super speed tube separator can also separate gas mixtures with different densities; the use of different types of centrifuges can also be used to separate gas mixtures with different densities Some centrifuges can also classify solid particles according to their density or particle size.

Centrifuges are widely used in chemical, petroleum, food, pharmaceutical, mineral processing, coal, water treatment and shipping departments.

The selection of centrifuge must be based on the size and concentration of solid particles in suspension (or emulsion), density difference between solid and liquid (or two liquids), liquid viscosity, and characteristics of filter residue (or sediment).

Price

The difference between domestic centrifuges and domestic centrifuges is not very big. China has already grasped the core technology of centrifuges. The price difference between centrifuges of the same grade is not very big, mainly in terms of performance and configuration.

The main difference is that in terms of performance, the centrifuge with refrigeration is much more expensive than ordinary centrifuges. Some centrifuges have heating function, and the more control programs, the higher the price of centrifuges. The big difference is in configuration. Sometimes the price of accessories is higher than that of the host. When purchasing, you should pay attention to the selection of rotors (quantity and type) in addition to the main engine, as well as the necessary centrifugal tube, tube sleeve, special centrifugal bottle or blood bag. All of these add up to the price of a complete centrifuge.
