PFA volumetric flasks are also known as imported PTFE volumetric flasks or Teflon volumetric flasks.

Common specifications include 10ml, 25ml, 50ml, 100ml, 250ml, 500ml, and 1000ml.

Product Characteristics

1. Resistant to strong acids and alkalis;
2. Low dissolution and precipitation, ensuring no contamination of samples;
3. High transparency for easy observation of sample volumes;
4. Strictly adheres to the one-thousandth weighing requirement, with clear electronic marking lines and calibration lines. Due to inherent limitations of plastic materials, which are susceptible to environmental factors such as air and temperature, users are advised to perform secondary calibration before use;
5. Essential in ICP-MS analysis; primarily used in laboratories for trace and ultra-trace analysis, isotope analysis, etc.;

6. As there is currently no national standard for the classification of plastic volumetric flasks such as PFA in China, we temporarily refer to the calibration standards for glass volumetric flasks, as detailed below:

Single-mark volumetric flasks

Through batch sampling and calibration by the Nanjing Institute of Metrology and Testing, the error values of our volumetric flasks meet the standards of glass volumetric flasks. For specific calibration values, please refer to the data issued by the Nanjing Institute of Metrology and Testing.
7. Applications: Widely used in trace analysis, isotope analysis, and other experiments such as ICP-MS and ICP-OES; applied in analytical laboratories across various industries including environmental testing centers, new materials, new energy, polysilicon, semiconductors, and more.
