First, large capacity benchtop low speed refrigerated centrifuge is mainly used to separate and purify cells, viruses, proteins and other macromolecules in biological samples. Its low temperature function can effectively protect samples from thermal damage and ensure that the structure and activity of biological macromolecules are preserved.
Secondly, in cytological research, this device is widely used in cell collection and washing steps in cell culture. When cells grow to a certain density in culture medium, researchers can use this device to efficiently precipitate cells while reducing the pressure and damage to the cells themselves.
In molecular biology experiments, large capacity benchtop low speed refrigerated centrifuge also plays an important role. For example, in the process of DNA extraction, after lysing cells, centrifugation is required to separate DNA and cell fragments. Since DNA molecules are large, low-speed centrifugation is sufficient to complete this step, and low temperature conditions help protect DNA from being damaged by degradative enzymes.
In addition, this device is also commonly used to prepare gradient solutions. In some specific experiments, such as density gradient centrifugation, it is necessary to prepare solutions with gradual density changes to separate cells or virus particles of different densities. The large capacity benchtop low speed refrigerated centrifuge can provide a stable rotation speed and a constant refrigerated environment to ensure the stability of the gradient solution and the separation effect.
In actual operation, to ensure the accuracy of the experimental results, the operator should follow strict operating procedures, including reasonable arrangement of centrifugation time, selection of appropriate speed and temperature settings, and proper handling of samples after the operation.
At the same time, the application of this equipment also requires attention to daily maintenance and care, such as regular inspection of the integrity of the various parts of the centrifuge, attention to the operating status of the centrifuge, and avoid long-term continuous operation.
