In many laboratories, there is a glass or plastic vessel composed of a hemispherical bottom and a cylinder, which is used to place radioactive or corrosive samples, which is a centrifuge tube. Where is it generally used? And what specific role does it have? What are the precautions when using it?

The function of centrifuge tube: it is made of plastic, glass or steel according to national standards and pharmaceutical industry standards, and it is not easy to be damaged. Generally, plastic centrifuge tubes are transparent or translucent, but their hardness is small and easy to deform. The corrosion resistance of organic solvents is poor, and the service life is short. The disadvantage of glass centrifuge tubes is that the sealing is not good enough, it is easy to lose balance, and it is easy to deform. The steel centrifuge tube has high strength, is not easy to deform, and has the functions of heat resistance, frost resistance and chemical corrosion resistance, which is suitable for some chemicals.

Precautions for centrifuge tubes: When using centrifuge tubes, do not use one tube multiple times. Pay attention to the volatilization of samples and the leakage of some radioactive or corrosive samples; in the storage process, it is necessary to seal them well; Prevent the centrifuge tube from being deformed during use.
