PFA volumetric flasks are also known as imported polytetrafluoroethylene 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 sample volume;

4. Strictly adheres to the one-thousandth weighing requirement, with clear electronic markings and calibration lines. Due to inherent defects in plastic materials, they are susceptible to environmental factors such as air and temperature. Therefore, users must 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 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 values, please refer to the data issued by the Nanjing Institute of Metrology and Testing.

7. Application Fields: Widely used in trace analysis such as ICP-MS, ICP-OES, isotope analysis, and other experiments; analytical laboratories in various industries including environmental testing centers, new materials, new energy, polysilicon, semiconductors, etc.
