Plastic centrifuge tubes have caps, which are used to prevent sample leakage, especially when 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 choosing this point, you should also pay attention to check whether the tube cover is tight, and whether it can be tightly covered during the test, so as to achieve the inversion without leakage;
We all know that in plastic centrifuge tubes, the commonly used materials are polyethylene (PE), polycarbonate (PC), polypropylene (PP), etc. Among them, polypropylene PP tubes have relatively good performance.
