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

Common specifications: 25ml, 50ml, 100ml, 250ml, 500ml

Product Features

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

6. As there is currently no national standard for grading PFA plastic volumetric flasks 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, our volumetric flasks meet the error tolerance standards of glass volumetric flasks. For specific calibration data, please refer to the official 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; applied in analytical laboratories across various industries including environmental testing centers, new materials, new energy, polysilicon, and semiconductors.
