Industrial Centrifuges are widely used in the fields of biomedicine, petrochemicals, agriculture, and food hygiene. They utilize the difference in sedimentation rates of different substances in a centrifugal force field to achieve sample analysis and separation. After the 1970s, high-speed industrial centrifuges developed rapidly. Due to their simple structure, low cost, and small size, benchtop high-speed industrial centrifuges quickly became routine instruments in laboratories. Today, industrial centrifuges and centrifuge technology are still continuously improving and evolving.
Numerous industrial centrifuges compete with each other, and the quality, technical performance, after-sales service, and price of the products remain the focus of attention for both manufacturers and users, so comprehensive consideration should be given when selecting a model.
Material characteristics include solid phase particles, density, liquid phase density, viscosity, and suspension concentration. For the selection of industrial centrifuges and filters, comprehensive consideration of the material's sedimentation and filtration characteristics is required.
The type of centrifuge should be determined based on the separation task and material characteristics, such as rotor, speed, capacity, and temperature. Generally, high-speed machines should not be used for low-speed tasks, and specialized machines should not be used for general purposes. General-purpose industrial centrifuges combine high-speed and low-speed capabilities, large capacity, and small volume, with the ability to fit multiple rotors, making them popular in research laboratories, albeit at a relatively higher cost.
Once the model is determined, further inspection of the product's technical data, technical performance, maintainability, safety, stability, reliability, safety standards, price, design, and appearance is necessary. Microcomputer control is superior to discrete component control; controlling and displaying the sample temperature is more practical than controlling and displaying the chamber temperature; higher precision of speed and temperature is better; more functions are better than fewer; a wider range of rotor options is better than narrower; and faster acceleration and deceleration is better than slower. These are all parameters that need attention.
For safety design, whether it is a high-speed industrial centrifuge or a low-speed industrial centrifuge, the more comprehensive the safety measures, the better. Higher automation is preferable, and more standard certification projects are better.
After-sales service from manufacturers is also a major factor for consideration. Industrial centrifuge maintenance is highly technical. It not only involves repair issues but also concerns quality and safety issues. After major repairs or when dealing with safety components, timely calibration according to requirements—such as imbalance detection, speed and temperature accuracy, electrical safety, and electromagnetic compatibility—should be performed. This should be particularly noted by users.
