Description
Additional Information

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

Common specifications include 10ml, 25ml, 50ml, 100ml, 250ml, 500ml, and 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, customers 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 grade certification of plastic volumetric flasks like PFA in China, we temporarily refer to the calibration standards for glass volumetric flasks, as detailed below:

Single calibration line volumetric flask

≤0.5

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 certification and calibration values, please refer to the data issued by the Nanjing Institute of Metrology and Testing.
7. Application fields: Widely used in trace analysis, isotope analysis, and other experiments such as ICP-MS and ICP-OES; analytical laboratories in various industries including environmental testing centers, new materials, new energy, polysilicon, semiconductors, etc.
