PFA Volumetric Flask, Constant Volume, Drop-Resistant And Durable, 500ml, Screw Top. (CAT#: STEM-WMA-0038-TP)

PFA volumetric flask, also known as volumetric flask, is a precision measuring instrument used to prepare a solution of a certain volume and concentration of a certain substance.

Specifications: 500ml, screw
Material: PFA
Withstand temperature: -200 to 260℃

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.
