Laboratory centrifuge is a specialized equipment for rapid separation, concentration and purification of different sedimentation coefficient mixtures by centrifugal force generated by high-speed rotation. It is widely used in medical and health, blood stations, pharmaceutical plants, biomedical engineering, animal and plant research, etc. A laboratory centrifuge is a device that produces constant acceleration. It is widely used in the fields of medicine, biology, and pharmacology to separate particles suspended in solution and to separate two different densities. Liquid.

Since different operating environments have different models for the selected laboratory centrifuges, only the centrifuges of the appropriate type can be used for the use of the centrifuges in the production process, and the industrial production can be improved. Overall efficiency. So how do people choose professional laboratory centrifuges for use in laboratories, hospitals, and food production and bioassays.

The type and structure of the laboratory centrifuge are expensive and the price is relatively expensive. When purchasing, it should be measured according to the needs of the work, so that the centrifuge can play its proper role economically and effectively. Usually should consider the following factors:

1 analytical centrifuge  or preparation of centrifuge;

2 separate the size of the sample;

3 separate the capacity of the sample;

4 sample temperature requirements.


According to these factors, whether to purchase the analytical centrifuge or the centrifuge; whether the centrifuge is low speed, high speed or overspeed; whether it is a large capacity centrifuge, a constant or a micro centrifuge; according to the temperature requirement, it needs a normal temperature centrifuge or a constant temperature Laboratory centrifuge. When the model is determined, the price of the centrifuge manufacturer (company) and the centrifuge should be considered. Generally, similar products can reach the main technical indicators, such as the rotational speed, the maximum centrifugal acceleration (relative centrifugal force), temperature, vacuum, capacity and so on.


Laboratory centrifuges, which are routine equipment for a laboratory, show differences in stability, safety, durability and humanity, simple and convenient maintenance, and the availability and reasonable price of consumable parts. There is also a matching problem in the purchase of centrifuges. Generally speaking, ultracentrifuges are limited to ultracentrifugation. It is not suitable for high-speed centrifugation and is not suitable for low-speed centrifugation. The same high-speed centrifuges are not suitable for long-time low-speed centrifugation. Promoted and used, it has achieved high and low speed universal, and can meet both high-capacity and low-speed freeze centrifugation and small-capacity high-speed centrifugation. From the perspective of scientific research and production in China, the low-speed and large-capacity centrifuges of the production units need the most, the scientific research units have the most low-speed centrifuges, the high-speed ones, and the ultra-speed applications are the least. The speed of the main engine of the centrifuge for work development can be appropriately increased. At present, the use of low speed and high speed is the largest, while the utilization rate of ultracentrifuge is low. The overspeed machine should be considered for its function and should not be purchased more. Analytical centrifuges are rare in practical applications and regional settings can be considered. Preparation and analysis of attachments is not suitable for analytical centrifugation work. At present, the ultracentrifuge has not been localized, so it is more prudent to purchase.
