In ultra-trace elemental analysis, every source of contamination matters. From sample digestion to solution preparation, laboratory vessels play a critical role in maintaining analytical accuracy. While glass volumetric flasks are widely used in routine laboratories, they are not always suitable for applications involving hydrofluoric acid (HF), ultra-low detection limits, or high-purity chemical preparation.
A high-purity PFA volumetric flask offers an ideal solution for these demanding analytical environments.
Virgin PFA provides exceptional chemical resistance and extremely low metal background, making it one of the preferred materials for trace elemental laboratories.
Compared with conventional glass volumetric flasks, PFA offers several important advantages:
Extremely low trace metal contamination
Excellent resistance to HF, HNO₃, HCl, aqua regia, and other aggressive acids
Non-wetting, easy-to-clean surface
Outstanding long-term chemical stability
Suitable for cleanroom and ultra-trace analytical applications
These properties make PFA volumetric flasks particularly suitable for laboratories using ICP-MS, ICP-OES, isotope analysis, and other high-sensitivity analytical techniques.
Although PFA laboratory bottles are widely available, large-volume PFA volumetric flasks remain difficult to source. Laboratories preparing high-purity reagents, calibration standards, or blank solutions often require larger capacities while maintaining accurate volumetric performance.
To meet this need, NJbinglab has developed a 2000 mL High-Purity PFA Volumetric Flask.
Key features include:
Virgin high-purity PFA construction
Manufactured according to Class A standards
Individual calibration certificate available
Leak-tight PFA screw cap
Suitable for ICP-MS and ultra-trace elemental analysis
Excellent resistance to HF, HNO₃, aqua regia, and other strong acids
Each flask is individually calibrated after the order is placed, and a calibration certificate issued by the Nanjing Institute of Metrological Supervision and Testing is available, providing the actual measured volumetric accuracy.
A large-volume PFA volumetric flask is suitable for:
Preparation of ICP-MS calibration standards
High-purity acid and reagent preparation
Geochemistry laboratories
Environmental trace element analysis
Semiconductor chemical laboratories
Nuclear and isotope research
Reference material preparation
Clean laboratory applications
In addition to our new 2000 mL model, NJbinglab also supports custom PFA laboratory vessels for laboratories with unique analytical requirements.
If you are looking for a high-purity PFA volumetric flask or other custom PFA labware for ultra-trace analysis, our engineering team is ready to help you develop the right solution for your application.
