Plastic centrifuge tubes have caps. Its function is to prevent sample leakage, especially when it is used for radioactive or highly corrosive samples. It is very important to prevent sample leakage; the tube cap also has a function to prevent sample volatilization. And support the centrifuge tube to prevent deformation of the centrifuge tube. When selecting this point, pay attention to check whether the tube cover is tight, and whether it can be closed tightly during the test, so as to ensure that it is inverted and does not leak;
We all know that among plastic centrifuge tubes, the commonly used materials are polyethylene (PE), polycarbonate (PC), polypropylene (PP), etc. Among them, the performance of polypropylene PP tube will be relatively good, so we are choosing plastic centrifuge When piping, consider polypropylene plastic centrifuge tubes as much as possible.
Plastic centrifuge tubes are generally disposable experimental instruments, and it is not recommended to reuse them multiple times. In order to save money, the PP centrifuge tube can be reused according to the situation, but it needs to be thoroughly sterilized by high temperature and high pressure to ensure the scientificity of the experimental results. The centrifuge tube made of PE cannot be sterilized by high temperature and high pressure.
Plastic centrifuge tube packaging or instructions generally indicate the centrifugal force or recommended speed that the product can withstand. In order to ensure the safety of the experiment and reliable results, a centrifuge tube that meets the requirements of the experimental speed should be selected.
