The process of using a centrifuge to separate the mixed liquid containing nanoparticles into solid and liquid is actually to use the density difference between the nano-powder and the liquid. Under the action of high-speed centrifugal force, the nano-powder and the liquid are rapidly stratified and then completely separated from the solid and liquid by the automatic discharge function of the centrifuge.

Due to their very small size, nanoparticles have very unusual physical and chemical properties. Practical applications targeting these properties range from the mundane, such as water-repellent and dust-resistant ("lotus leaf effect") surfaces, to the exotic, such as special functions for medical, optical or microprocessor technology.

The centrifuge is used for the analysis and production of nanoparticles; the GL21M/GL10MA large-capacity centrifuge produced by Kaida occupies a unique position in this respect, with a processing capacity of more than 3L at a time, greatly improving work efficiency.
