The sack sampler is made of high-purity polytetrafluoroethylene (PTFE). It can efficiently and quickly take samples from the sack while preventing the sample from being contaminated by other impurities when it is taken out. The surface of PTFE is smooth and the sample will not adhere to the surface.
PTFE Features:
1. Pure white appearance.
2. High and low temperature resistance: can be used at -200℃~+250℃.
3. Corrosion resistance: resistant to strong acid, strong alkali, aqua regia and organic solvents, and no dissolution, adsorption and precipitation.
4. Anti-pollution: low blank value of metal elements.
5. Insulation: not affected by environment and frequency, low dielectric loss.
6. Resistant to atmospheric aging, radiation and low permeability.
7. Self-lubricating: has a small friction coefficient among plastics.
8. Soft mechanical properties, with very low surface energy.
