PFA, also known as soluble polytetrafluorethylene or Teflon, is resistant to strong acid and alkali and high and low temperature. It is mainly used for trace analysis, isotope detection, ICP-MS/OES/AAS analysis and other high-end experiments. The chemical stability of PFA material can significantly reduce cross contamination, the lowest friction coefficient in plastics, and good electrical performance, its electrical insulation is not affected by temperature, known as the
1. Translucent appearance;
2, high temperature resistance: use temperature
3, corrosion resistance: resistance to strong acid, alkali, aqua roya, hydrofluoric acid and various organic solvents;
4, insulation resistance: dielectric properties and temperature, frequency independent;
5. Anti-pollution: low blank value of metal elements;
6, very low dissolution and precipitation: is the storage of standard materials, strong corrosive, expensive ultra-high purity reagents of the excellent vessels;
7, nozzle and cap molding: open can autoclaving;
8. It can replace the standard solution of the volumetric flask: it can be controlled to add sample and water in the state of drop by drop, and there is no residue in the return water nozzle.
