1、 Principle

　　Floor standing high-speed centrifugeThe core working principle is to use centrifugal force to achieve material stratification and separation. After the centrifuge is started, its rotor begins to rotate at high speed, usually reaching thousands or even tens of thousands of revolutions per minute. The sample to be separated is placed in the sample container of the rotating head and rotates together with the rotating head. Due to the differences in physical properties such as density and particle size of different substances, they experience different outward forces under the action of centrifugal force field. Substances with higher density and larger particles tend to settle faster to the outer layer of the centrifuge tube, while substances with lower density and finer particles tend to remain near the axis. In this way, multiple substances that were originally mixed together are gradually separated, achieving precise stratification by composition or particle size.

2、 Structural analysis

The structural design carefully considers stability and functionality. Its base is wide and heavy, made of high-quality metal materials, designed to provide solid support for the entire equipment during high-speed operation, ensuring that it will not shift or tilt due to vibration and ensuring operational safety. The rotor of a centrifuge is one of the key components, and there are various types to choose from according to different application requirements. For example, the angular rotor is suitable for differential centrifugation, which can quickly separate different components in the sample under centrifugal force; The flat rotating head is more conducive to separating substances with similar particle sizes but different densities. It can form a uniform thin layer of the sample during the rotation process, improving the separation effect. The rotary head is usually equipped with a high-precision bearing system inside, ensuring its stability and low-noise operation during high-speed rotation. The outer shell not only serves as a protective measure to prevent operators from accidentally coming into contact with high-speed rotating components, but also has good ventilation and heat dissipation functions. During high-speed centrifugation, components such as motors generate a large amount of heat, and timely heat dissipation can ensure the normal operation and service life of the equipment.

3、 Application Fields

In the field of biopharmaceuticals, high-speed centrifuges play an irreplaceable role. In the process of new drug development, it can be used for the extraction and purification of active ingredients in drugs, separating high-purity drug molecules from complex biological systems, laying the foundation for subsequent drug formulation development.

In the food industry, it is widely used in food safety testing and food raw material processing. For example, in the quality inspection of edible oil, impurities, moisture, and suspended solids in the oil can be removed by centrifugation, ensuring the purity and quality of the oil. In the juice production process, the use of high-speed centrifuges can effectively separate solid components such as fruit pulp residue and cellulose in the juice, obtaining clear and transparent juice solution, and improving the taste and appearance quality of the product.

The chemical industry has also benefited greatly. In the treatment of mixtures after chemical reactions, it can quickly separate the solid products generated by the reaction from the liquid solvent, facilitating further purification and analysis of the products. For the preparation process of some nanomaterials, centrifuges can assist in separating nanoparticles of different sizes, controlling the particle size distribution of the material and optimizing its performance.

4、 Highlight advantages

　　Floor standing high-speed centrifugeCompared to other separation devices, it has significant advantages. Firstly, its efficient separation capability enables it to process a large number of samples in a short period of time, improving work efficiency. For example, in large-scale blood screening work, it can quickly perform serum separation on numerous blood samples to meet the needs of high-throughput testing. Next is the precision of separation. With precise speed control and optimized centrifugal force field design, it is possible to accurately separate layers according to the characteristics of the substance, ensuring the purity and accuracy of the obtained sample. Furthermore, it has high reliability and can maintain stable performance over a long period of use through strict quality testing and manufacturing processes, reducing experimental or production delays caused by equipment failures.

5、 Key points of operation and maintenance

The operation of high-speed centrifuges requires strict adherence to standardized procedures. Before operation, carefully check whether the sample is placed in balance to avoid excessive vibration and equipment damage caused by imbalance. At the same time, accurately set parameters such as centrifugal speed, time, and temperature based on the properties of the sample and separation requirements. During use, pay close attention to the operating status of the equipment. If any abnormal noise or excessive vibration is found, stop the machine for inspection in a timely manner.

Daily maintenance is crucial for extending the service life of centrifuges. Regularly clean the rotor and sample container to prevent the accumulation and corrosion of residual substances. Regularly lubricate and maintain the transmission components, bearings, etc. of the equipment to ensure smooth operation.
