What is the role of a high speed centrifuge?

High-speed centrifuge is a routine laboratory centrifuge, widely used in research, education and production departments of biology, chemistry, medicine, etc. It is used in laboratories, scientific research, schools and other departments, and is suitable for rapid separation and synthesis of trace samples.

The high-speed centrifuge mainly extracts the required components from the liquid mixture. According to the density of each substance, after high-speed rotation, the dense liquid sinks to the bottom layer, and the small density liquid floats on it, thus stratifying the liquid. Refine the pure things I need. It is used in many fields such as medicine and chemical industry.

Centrifugal tubes for high speed centrifuges are typically made of plastic and polypropylene, polyethylene, polycarbonate or borosilicate glass, borosilicate plastic, and the like. In practice, various centrifuge tubes can be selected according to different requirements.

When a substance is precipitated in a medium, it is accompanied by a diffusion phenomenon. The diffusion is unconditional and absolute. The smaller the particle size of the substance, the larger the range of diffusion. The sedimentation is subject to the external force. The interview is conditional, and the mass of the object is larger. The faster the sedimentation rate, the high-speed refrigerated centrifuge is available because some of the particles are too small to see the sedimentation process.

The main working principle of high-speed centrifuge: high-speed centrifuge is the powerful centrifugal force generated by high-speed rotation of the high-speed centrifuge frozen centrifuge rotor to accelerate the sedimentation speed of particles in the liquid, and separate the sedimentation coefficient and buoyant density of the sample.

Centrifuge is a kind of machine that performs solid-liquid, liquid-liquid or solid-liquid phase separation under the action of centrifugal force. The rotor is the main component of the centrifuge. It is mostly made of titanium alloy or aluminum alloy. It is installed at high speed. Separation is achieved by centrifugal force on the vertical or horizontal axis, and can be used for separation of centrifugal separation, centrifugal filtration and centrifugal sedimentation. The separation factor is the main indicator of the separation performance of the centrifuge. It is the ratio of the centrifugal force to the gravity of the material, which is equal to the ratio of the centrifugal acceleration to the gravity acceleration.
