Product Introduction

Common specifications: 25ml, 50ml, 100ml, 250ml FEP volumetric flasks, also known as Teflon volumetric flasks, are precise measuring vessels used for preparing solutions of a specific molar concentration, often used in conjunction with pipettes. Widely applied in high-end experiments such as ICP-MS, ICP-OES trace analysis, and isotope analysis. Utilized by institutions including geology, electronic chemicals, semiconductor analysis and testing, disease control centers, pharmaceutical factories, and environmental testing centers.

Product Characteristics

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

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

3. Transparent and colorless appearance, facilitating observation;

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

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

6. Teflon FEP volumetric flask is a transparent long-necked flask with a pear-shaped body, making it easy to swirl liquids and clean, 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 HF;

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

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