PFA digestion tube is mainly used for sample digestion before chemical analysis. The chemical stability of PFA material can significantly reduce cross contamination. Its friction coefficient is very low in plastics. It also has good electrical properties. Its electrical insulation is not affected by temperature. It is known as the king of plastics. characteristic: 1. The appearance is translucent, with 30ml and 60ml specifications: U-shaped bottom, V-shaped bottom and flat bottom; 2. High and low temperature resistance: service temperature - 200+260 3. Corrosion resistance: resistant to strong acid, alkali, aqua regia, hydrofluoric acid and various organic solvents; 4. Insulation resistance: the dielectric property is independent of temperature and frequency, and the radiation resistance is excellent; 5. Anti pollution: low blank value of metal elements; 6. With low dissolution and precipitation, it is a good container for storing reference materials, highly corrosive, expensive and ultra-high purity reagents; 7. Drop from a height of 1.2m above the ground, and the bottle body will not crack, the bottle cap will not fall off, and there will be no leakage
