PFA Volumetric Flask, 25ml, Screw Top. (CAT#: STEM-WMA-0031-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 0.16ppb, 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.

Specifications: 25ml, screw
Material: PFA
Withstand temperature: 260℃

The chemical stability of PFA material can significantly reduce cross-contamination, as well as good electrical properties
1. High and bottom temperature resistance: the operating temperature is -200 ~ +260 ℃, and its mechanical strength can be maintained within a large temperature difference.
2. Corrosion resistance: strong acid, strong alkali, aqua regia, hydrofluoric acid and various organic solvents;
3. Compared with similar products of polytetrafluoroethylene, 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; and the bottle has a scale line, which is accurate in quantification and error. little;
4. Easy to clean: PFA itself is not sticky and has the ability to waterproof, oil and other substances, the surface is smooth and smooth, without any scratches, in the process of use, easy to clean, to meet the needs of demanding trace analysis experiments.
