Description
Additional Information

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 precipitation, non-contaminating to samples;
3. High transparency for easy observation of volumetric samples;
4. Strictly meets the one-thousandth weighing requirement with clear electronic markings 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/ultra-trace analysis, isotope analysis, and other laboratories;

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

Through batch sampling and calibration by the Nanjing Institute of Metrology and Testing, our volumetric flasks meet the error 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. Application fields: Widely used in trace analysis such as ICP-MS, ICP-OES, isotope analysis, and other experiments; analytical laboratories in environmental testing centers, new materials, new energy, polysilicon, semiconductors, and various other industries.
