Centrifuge Tube Cap Function

We all know that common materials used in plastic centrifuge tubes include polyethylene (PE), polycarbonate (PC), and polypropylene (PP). Among these, polypropylene (PP) tubes generally have better performance. Therefore, when selecting plastic centrifuge tubes, we should consider polypropylene tubes whenever possible.

The functions of the tube cap are:
1. To prevent sample leakage when using radioactive or highly corrosive samples.

2. To prevent sample evaporation.

3. To support the centrifuge tube and prevent deformation.
