A benchtop low-speed refrigerated centrifuge  is a common laboratory device used to separate materials of different densities, shapes, and sizes. It has the advantages of high automation, wide application and high precision, and has become one of the important tools for laboratory separation, purification and analysis. The principle is based on centrifugal separation, which uses centrifugal force to separate substances into different layers in a centrifugal tube. Generally speaking, the equipment includes the main components of the centrifuge body, rotor, centrifugal tube, cooling system, control system and so on.

The centrifuge body is the basic structure of the equipment, and its role is to provide support and protection for other components. The rotor is an important part of the centrifuge, and its rotation speed and centrifugal force directly determine the rate and effect of separating substances. The centrifugal tube acts as a sample container, which can hold samples of different sizes and shapes. The sample is placed in the centrifugal tube, and when the rotor is rotated, the centrifugal force separates the sample into different layers. The cooling system is the key link to ensure that the sample in the centrifugal tube is not affected by temperature. The cooling system can control the rotor and the centrifugal tube at low temperature, so that the sample will not suffer heat loss during the centrifugal process and ensure the accuracy of the experimental results. Finally, the control system can precisely control and adjust the parameters such as speed, time and temperature to ensure the accuracy and reproducibility of the experimental data.

In terms of application, the desktop low-speed refrigerated centrifuge has a wide range of application fields and functions, such as cell separation, protein separation, nucleic acid separation, preparation of viruses and purified products. In cytology, it can be used to separate different types and densities of cells, such as white blood cells, red blood cells and neurons. In molecular biology research, it can be used to separate proteins, DNA, RNA and other molecules, and analyze and purify them. At the same time, it can also be used in the preparation of virus products, purification of plant extracts, and preparation of high-quality products and other fields.

In short, desktop low-speed refrigerated centrifuge , as a common laboratory equipment, has an important position and role in different fields and applications. Its high degree of automation and accuracy makes it more convenient and accurate for experimenters to separate and purify samples, which guarantees the accuracy and reproducibility of experimental results. With the development and application of science and technology, it is believed that it will have more extensive and in-depth applications in the future.
