Product Introduction

Common Specifications: 25ml, 50ml, 100ml, 250ml. FEP volumetric flasks, also known as Teflon volumetric flasks, are precise measuring vessels used for preparing accurate molar concentrations of solutions, often used in conjunction with pipettes. They are widely used in high-end experiments such as ICP-MS, ICP-OES trace analysis, and isotope analysis. Institutions include geology, electronic chemicals, semiconductor analysis and testing, disease control centers, pharmaceutical factories, environmental testing centers, and others.

Product Features

High and low temperature resistance: operating temperature range from -200°C to +205°C;

Resistant to strong acids, strong bases, and other organic solvents;

3. Transparent and colorless appearance for easy observation;

4. Excellent chemical resistance, capable of withstanding almost all chemical solvents;

5. High transparency, allowing visible inspection of the liquid inside the container;

6. Teflon FEP volumetric flask is a transparent long-neck flask with a pear-shaped body, facilitating liquid agitation and cleaning, and can replace expensive PFA volumetric flasks on the market;

7. Suitable only for preparing standard solutions, not for long-term storage of solutions;

8. Must be rinsed with water after use;

9. Primarily used for experiments requiring strong acids and bases, especially hydrofluoric acid;

10. Similar to glass volumetric flasks, each FEP volumetric flask's calibration line is precisely weighed and marked using a 0.001g electronic balance. Laser-engraved lines;

11. Compared to PTFE volumetric flasks, FEP volumetric flasks offer better transparency and are reliable products for laboratory volumetric measurements. Due to regional variations, calibration lines on plastic volumetric flasks may be affected, so recalibration by the user is recommended!
