The electric centrifuge is a commonly used separation equipment in laboratory and industrial production, which can separate precipitation and solutions, high-viscosity solutions, emulsions and other substances. It relies on high-speed rotation to generate centrifugal force, and the magnitude of centrifugal force is affected by the density of matter, the speed of the motor, and the radius of rotation.
classify
According to the speed, it is divided into three categories: low speed (≤8000r/min), high speed (8000 - 28000r/min), and overspeed (28000 - 120000r/min).
By application, it is divided into preparative type (for separation and purification) and analytical type (detectable particle parameters)
According to the structure, there are floor type (suitable for handling large sample volumes) and benchtop type (suitable for small-scale experiments). In addition, there are classifications such as capacity, refrigeration function, etc.
Basic parameters
It is determined by the host and rotor, including the maximum speed, the maximum preparation capacity, the maximum relative centrifugal force field, etc. These parameters affect the performance and range of application of the centrifuge, such as the maximum speed determines the difference in particle size and density of the separable substance, and the temperature control accuracy affects the protection of the sample by the refrigerated centrifuge.
Ordinary type and high-speed freezing type
Ordinary centrifuges are typically available with 6 tubes with caps, volumes from 10 to 20 ml, and rotational speeds from 0 to 8000 r/min, which are suitable for routine separations. The high-speed refrigerated centrifuge has a speed of up to 24,000 r/min, a temperature of -20°C to +40°C, is computer-controlled, safeguarded, and the rotor can be changed as required.
apply
In the biological field, it is used for cell separation, protein purification,Medically involved in blood analysis, clinical examination,In the field of chemistry, it is used for the separation and purification of substances,Environmental protection industry to treat sewage and monitor the environment,In the food field, it is used for dairy production and food testing, and is an important equipment for scientific research and production.
summary
With its diverse classification and precise parameter control, the electric centrifuge has become the core tool for the separation of substances in modern scientific research and industrial production. From basic laboratories to high-end production scenarios, it promotes technological progress in biological, medical, chemical and other fields with its high-efficiency separation capabilities, and its continuously optimized performance will continue to provide key support for the development of various industries.
