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 highly corrosive samples. It 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 the centrifuge tubes: It is made of plastic, glass or steel according to the requirements of national standards and medical industry standards. It is not easy to be destroyed. Generally, the plastic centrifuge tube is transparent or translucent, and its hardness is small and easy to deform. The corrosion resistance of organic solvents is poor, and the service life is short. The disadvantage of the glass centrifuge tube 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 also has the effects of heat resistance, frost resistance, and chemical corrosion resistance. It is suitable for some chemicals.
Precautions for the centrifuge tubes: When we use the centrifuge tube, do not use one tube multiple times, pay attention to the volatilization of the sample and the leakage of some radioactive or corrosive samples; in the storage process, it must be sealed; Prevent the centrifuge tube from being deformed during use.
