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

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

Product Features

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

6. As there are currently no national standards for the classification of plastic volumetric flasks like 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 data, please refer to the reports issued by the Nanjing Institute of Metrology and Testing.
7. Applications: Widely used in trace analysis, isotope analysis, and experiments such as ICP-MS and ICP-OES; analytical laboratories in various industries including environmental testing centers, new materials, new energy, polysilicon, and semiconductors.
