The blank value of metal elements in the product is low, the content of lead and uranium is less than 0.01ppb, no dissolution and precipitation, no adding back material has a very low background, it not only has good resistance to temperature and various chemical reagents, but also has the advantages of convenient cleaning. Mainly used for trace analysis, isotope analysis and other high-end experimental product characteristics: 1, difficult jointless integrated mold production technology, to ensure the stability of product quality, long service life; 2. The chemical stability of PFA material can significantly reduce cross contamination, the friction coefficient is the lowest in plastics, and there is good electrical performance, and its electrical insulation is not affected by temperature. 3, high temperature resistance: the use of temperature -200 ~ +260â??, in the large temperature difference, can maintain its mechanical strength: from very low to very high temperature, PFA can maintain its flexibility without reducing toughness, and PTFE is the same, which is the highest continuous use of all fluorocarbon polymer temperature. 4, corrosion resistance: resistance to strong acid, alkali, aqua aqua, hydrofluoric acid and various organic solvents; 5, compared with similar products of polytetrafluoroethylene, its high transparency, the specific experimental process, the experimenter can observe the reaction of the sample in the cup at any time, convenient for the experiment; Moreover, the cup body has a precise calibration line, which is accurate in quantification and has minimal error, which can meet the quantitative requirements of routine experiments. 6, easy to clean: PFA itself is non-stick and has the ability to waterproof, oil and other substances, the surface is smooth, without any scratch, in the process of use, easy to clean, to meet the demanding trace analysis experiment needs.
