1. Translucent appearance, easy to observe the reagents in the tank;
2. High and low temperature resistance: -200~+260℃
3. Corrosion resistance: strong acid, strong alkali, aqua regia, HF and various organic solvents;
4. Insulation resistance: dielectric properties are independent of temperature and frequency;
5. Anti-pollution: low background value, metal element lead and uranium content is less than 0.01ppb;
6. Low dissolution and precipitation, will not pollute experimental utensils, etc.;
8. Stable chemical properties, good recoverability, not easy to deform;
9. Teflon plastic, durable and not easy to break.
