Preparation analysiscentrifugeA centrifuge that can not only separate, concentrate, and purify samples, but also observe, photograph, measure, digitally output, print, and automatically display the settling process of samples through an optical system.
　　
Classified by rotational speed: divided into low-speed centrifuge, high-speed centrifuge, and high-speed centrifuge.
　　
low speedcentrifugeThe rotational speed is within 10000rpm or the relative centrifugal force is within 15000 × g.
　　
High speed centrifuge: speed within 10000-30000rpm or relative centrifugal force within 15000-7000xg.
　　
Overspeed centrifuge: The speed is above 30000rpm or the relative centrifugal force is above 70000 × g.
　　
Classified by structure:
　　
Usually at high and low speedscentrifugeClassified by structure and function, there are numerous varieties, and there is no unified standard for naming among manufacturers. It can be divided into desktop centrifuge, multi tube micro desktop centrifuge, cell smear centrifuge, blood washing desktop centrifuge, high-speed freezing centrifuge, large capacity low-speed freezing centrifuge, low-speed freezing centrifuge, desktop high-speed freezing centrifuge, desktop low-speed automatic balancing centrifuge, etc. In addition, there are also triple (five) high-speed cryogenic centrifuges abroad, specifically designed for continuous centrifugation.
　　
A centrifuge is a mechanical device that uses centrifugal force to separate components in a mixture of liquid and solid particles or liquid and liquid.
　　
leavecentrifugeMainly used to separate solid particles from liquids in suspension; Or separate two immiscible liquids with different densities in the emulsion (such as separating cream from milk); It can also be used to remove liquids from wet solids, such as using a washing machine to spin dry and wet clothes; The special high-speed tube separator can also separate gas mixtures of different densities; By taking advantage of the different settling velocities of solid particles with different densities or particle sizes in liquids, some settling centrifuges can also classify solid particles according to density or particle size.
