PFA Volumetric Flask, Resistant To Strong Acid And Alkali, 1000ml, Screw Top. (CAT#: STEM-WMA-0045-TP)

Highlights

1. The chemical stability of PFA can significantly reduce cross-contamination, the friction coefficient is very low in plastics, and it has good electrical properties. Its electrical insulation is not affected by temperature, and it is known as the "plastic king";
2. The operating temperature is -200~+260℃, and its mechanical strength can be maintained in a large temperature difference: from low to high temperature, PFA can maintain its flexibility without reducing its toughness, which is the same as PTFE, which is the same as all fluorocarbon polymers. Continuous use temperature.
3. Corrosion resistance: resistant to strong acid, strong alkali, aqua regia, hydrofluoric acid and various organic solvents;

Cat Number: STEM-WMA-0045-TP

Application: The volumetric flask is a measuring device.

Description

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 0.21ppb, 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.

Specification

Material: PFA
Withstand temperature: -200 to 260℃

Features

1. The chemical stability of PFA can significantly reduce cross-contamination, the friction coefficient is very low in plastics, and it has good electrical properties. Its electrical insulation is not affected by temperature, and it is known as the "plastic king";
2. The operating temperature is -200~+260℃, and its mechanical strength can be maintained in a large temperature difference: from low to high temperature, PFA can maintain its flexibility without reducing its toughness, which is the same as PTFE, which is the same as all fluorocarbon polymers. Continuous use temperature.
3. Corrosion resistance: resistant to strong acid, strong alkali, aqua regia, hydrofluoric acid and various organic solvents;
4. 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 precise scale line, which is accurate and quantitative. The error is small and can meet the A-level standard;
5. 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 demanding requirements of trace analysis experiments.
