Imported PFA volumetric flask with calibration certificate.

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 compliant with one-thousandth weighing requirements, with clear electronic graduation lines 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 laboratories for trace and ultra-trace analysis, isotope analysis, etc.;

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

Single-mark volumetric flask

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