7ml PFA vial, U/V/flat bottom, with screw cap
Extreme Purity: Lowest metal ion leaching of any fluoropolymer; essential for ppt-level trace analysis.
Wide Temp Range: Exceptional stability from -200°C to +260°C, outperforming FEP in high-heat applications.
Universal Inertness: Immune to nearly all chemicals, including concentrated HF, aqua regia, and organic solvents.
Hydrophobic Surface: Non-stick interior ensures near-total sample recovery and effortless cleaning.
Superior Sealing: Precision-threaded PFA caps provide a liquid-tight, contamination-free seal without liners.

PFASpecification :
7ml, U/V/flat bottomPFA Vials represent the pinnacle of sample containment technology for ultra-trace analysis. While similar to FEP, PFA (Perfluoroalkoxy) offers enhanced thermal resistance and even lower background contamination, making it the industry standard for ICP-MS sample preparation. These vials are translucent, unbreakable, and designed with a smooth bottom contour to ensure maximum pipette recovery of precious or limited samples.
Engineered for a seamless, ultra-clean analytical workflow:
FEP Reagent Bottles: Used for bulk storage of the high-purity acids used to dilute samples within the PFA vials.
PFA Pipette Tips: The perfect partner for moving microliter volumes into vials without introducing trace metal artifacts.
Hot Blocks & Digestion Systems: PFA vials are ideal for open or closed-vessel acid digestion due to their high thermal ceiling (260°C).
PFA Autosampler Vials: Specifically sized to fit standard ICP-MS/OES autosampler racks for direct instrument injection.
Semiconductor Industry: Analysis of ultra-pure water (UPW) and photoresist chemicals where sub-ppt purity is required.
Geochemistry & Geochronology: Dissolution of rock and mineral samples using concentrated acids over extended periods.
Clinical & Forensic Toxicology: Safe storage of biological fluids and detection of heavy metal poisoning at trace levels.
Space & Earth Sciences: Handling of rare extraterrestrial materials or deep-sea sediments where sample integrity is paramount.
