High Speed Centrifuge 

High-speed centrifuge is a conventional laboratory centrifuge, widely used in biology, chemistry, medicine, and other scientific research, education, and production departments, it uses the strong centrifugal force generated by the high-speed rotation of the rotor to separate the components of liquid and solid particles or liquid mixtures, suitable for the rapid separation of micro-sample synthesis.

Basic Principles Of High Speed Centrifuge

When a suspension containing fine particles is left standing, the gravitational field makes the suspended particles gradually sink. The heavier the particles, the faster they sink, and conversely, the particles with a density smaller than that of the liquid will float. Particles in the gravitational field of the speed of movement and particle size, form, and density, and with the strength of the gravitational field and the viscosity of the liquid. Particles the size of red blood cells, with a diameter of several microns, can be observed in the usual gravitational effect of their sedimentation process. In addition, the settling of substances in the medium is accompanied by diffusion phenomena.

Diffusion is unconditional and absolute. Diffusion is inversely proportional to the mass of the substance; the smaller the particle, the more severe the diffusion. Sedimentation is relative, conditional, and subject to external forces in order to move. Settling is proportional to the weight of the object, the larger the particle, the faster it settles. For particles smaller than a few microns, such as viruses or proteins, which become colloidal or semi-colloidal in solution, it is not possible to observe the settling process using gravity alone.

the smaller the particles, the slower they settle, and the more severe the diffusion phenomenon. Therefore, it is necessary to use high speed centrifuges to generate strong centrifugal forces in order to force these particles to overcome diffusion to produce a settling motion. Centrifugation is the use of the powerful centrifugal force generated by the high-speed rotation of the rotor of the centrifuge to accelerate the settling speed of the particles in the liquid and to separate the substances with different settling coefficients and buoyancy densities in the sample.

Applications Of High Speed Centrifuge

High speed centrifuges generally have a rotational speed between 10,000 and 30,000 r/min and are equipped with a chilling system. Due to the high rotational speed and high centrifugal force, it is an effective preparation instrument for high purity separation, concentration, and refinement of suspended substances in sample solution and extraction of various samples for research. It is an important instrument used in medical, pharmacy, biology, chemistry, agricultural science, food and environmental protection, and other scientific research and production departments, and is widely used for various drugs and biological products, such as blood, cells, proteins, enzymes, nucleic acids, viruses, hormones and so on.
