PFA Volumetric Flask, Threaded, Sealed, Plastic Volumetric Flask For Elemental Analysis, 250ml, Screw Top. (CAT#: STEM-WMA-0049-TP)

More and more trace analysis experiments require the determination of ultra-low concentrations in the ppb and ppt levels. The general materials currently used will inevitably react with the stored samples, reagents or standard solutions without special treatment, resulting in incorrect results in trace analysis experiments. Our PFA volumetric flask can just make up for its shortcomings. It has a low blank value of metal elements, the content of lead and uranium is less than 0.25ppb, no dissolution and precipitation, and a very low background. It not only has good resistance to temperature and various chemical agents, but also has the advantages of convenient cleaning. This product is mainly used for trace analysis, isotope analysis and other experiments.

Specifications: 250ml, screw
Material: PFA
Withstand temperature: -200 to 260℃

1. The chemical stability of PFA can significantly reduce cross-contamination, the friction coefficient is the lowest among plastics, and it has good electrical properties, and its electrical insulation is not affected by temperature;
2. High and bottom temperature resistance: the operating temperature is -200 ~ +260 ℃, and its mechanical strength can be maintained within a large temperature difference.
3. Corrosion resistance;
4. Compared with similar products of PTFE, it has a high degree of transparency. During the specific experiment process, the experimenter can observe the reaction of the sample in the cup at any time, which is convenient for the experiment;
5. Easy to clean: PFA itself is not sticky and has the ability to waterproof, oil and other substances.
