How to make a low speed centrifuge truly satisfying

2018/3/9 9:58:45      click :

There are many Low-speed centrifuges on the market, but few are satisfied. To achieve sustainable development in today's society, practicality is the focus, but appearance design is also very important. In Hailu Xiang-centrifugal machines for the needs of the industry, the production of ergonomic centrifuge, aerodynamic design, safer and beautiful and practical.


The Low-speed centrifuge adopts microcomputer control, large screen TFT LCD screen and digital screen, to meet the requirements of several customers. Completely steel structure, stainless steel centrifugal chamber, resistant and durable. Low speed centrifuge is designed for hospitals, blood banks, RIA, nuclear medicine and other special units designed by the centrifugal effect at the same time, completely solve the hospital hat in a separate vacutainer problem, it is the most innovative, most advanced, more efficient Separation equipment Automatic lid extraction is a conventional laboratory centrifuge, widely used in clinical medicine, biochemistry, immunology, blood stations, medicine and other departments of education and production of scientific research.


The principle of low speed centrifugal centrifugation and two sedimentation. Centrifugation is a suspension was produced under the centrifugal field of the centrifugal pressure acting on the filter medium, the liquid through the filter media to be filtered, and the solid particles are trapped on the surface of the filter medium, thereby realizing a liquid - solid separation; Centrifugal sedimentation using The principle that components with different suspension (or emulsion) density settle out quickly and stratify in the centrifugal force field can perform liquid-solid (or liquid-liquid) separation. Another type of separator used for the experimental analysis, can be a clear liquid and solid particles enriched or liquid - separation of liquids, such separators have a normal pressure, a vacuum, a different type of structure that operates under refrigeration conditions. Strengthen the separation capacity including increasing the rotation speed of the drum, add a new impulse in the centrifugal separation process, the accelerated speed to push the slag; drum length increase of similar prolonged centrifugal sedimentation separation. The development of large low-speed centrifuge, mainly to increase the use of double-sided drum drum diameter and increase the processing capacity of the unit of coating material handling equipment volume, reduce energy consumption and maintenance costs. In terms of theoretical research, the study focused mainly on the conditions of fluid flow in the drum and the mechanism of filter residue formation, and studied the calculation method of minimum separation and processing capacity.

 

The successive centrifugal centrifuge centrifugal speed increases strength, each component can be set some of the sample solution. Low speed centrifugation is the most common method. In this method, the centrifuge tube is filled with a uniform sample solution. After centrifugation at a certain speed for a certain period of time, two fractions can be obtained: sediment and supernatant. Most unwanted large particles are usually sedimented and removed during the first centrifugation. Most of the components required at this time remain in the supernatant. The collected supernatant is centrifuged at a higher speed to deposit the desired particles. The centrifugation time should be chosen so that most of the unwanted small particles remain in the supernatant. The resulting pellet and supernatant can be further centrifuged until the desired separation purity is achieved. Low speed centrifugation is characterized by a simple operation but a considerable separation purity.


Low-speed centrifuge using different density or particle size of the solid particles in a liquid sedimentation rate of different characteristics, some of the decanter centrifuge further classify solid particles according to the density or particle size. It is the use of the high-speed rotation of the centrifuge rotor a strong centrifugal force, the liquid up to the sedimentation rate of the particles in the sample and a different substances separated sedimentation coefficient of flotation density. It is necessary to use a centrifuge to produce a strong centrifugal force to overcome the force of these diffuser particles generates movement of the settlements. Centrifuges are machines that use centrifugal force to separate the components of a mixture of liquid and solid or liquid and liquid particles. Mainly low speed centrifuge to separate solid particles from a liquid suspension; or emulsion of two different densities, and separate immiscible liquids (separating for example milk cream), but it can also be used for negative liquid wet solids, the strong centrifugal force is centrifuged using a high speed rotation of the rotor of the centrifuge, accelerate the rate of sedimentation of the particles in a liquid, the sample and a different substances separated sedimentation coefficient of flotation density.
