Description

Technical Field

[0001] The invention relates to the technical field of centrifuges, in particular to an ultra-speed refrigerated centrifuge. Background Art

[0002] Centrifuges have a wide range of applications in the medical industry. They are mainly used in blood separation, DNA research, immunohematology laboratories, inspection rooms, research rooms, etc. They are ideal products for medical and biochemical laboratories for serum, plasma, and radioimmunoassay. They are essential equipment for blood banks, laboratories, blood stations, medical schools, and medical research institutions in various hospitals. The main working principle of medical high-speed refrigerated centrifuges is that when substances precipitate in a medium, they are also accompanied by diffusion. Diffusion is unconditional and absolute. The smaller the particles of a substance, the larger the range of diffusion. Sedimentation is conditional to the action of external forces. The greater the mass of an object, the faster it settles. Therefore, high-speed centrifuges are used. High-speed refrigerated centrifuges use the strong centrifugal force generated by the high-speed rotation of the rotor of a high-speed refrigerated centrifuge to accelerate the sedimentation rate of particles in the liquid and separate substances with different sedimentation coefficients and buoyancy densities in the sample.
