Designed for ultra-clean analytical workflows, this PTFE (Polytetrafluoroethylene) Volumetric Flask is an essential piece of premium labware for chemical analysis, isotope detection, and precise volume measurement of aggressive corrosive solutions. Unlike glass, PTFE prevents ion contamination and withstands extreme thermal and chemical environments, making it ideal for trace metal analysis, pharmaceutical R&D, and semiconductor testing.
Key Features:
-
Extreme Temperature Resistance: Operates reliably across an ultra-wide temperature range from -196°C to +250°C (-320°F to +482°F) while maintaining 5% elongation toughness at low temperatures.
-
Superior Chemical Inertness: Resistant to virtually all chemical reagents, including strong acids, bases, aqua regia, HF (hydrofluoric acid), and organic solvents.
-
High Lubricity & Non-Stick Surface: Features the lowest friction coefficient among solid materials, preventing liquid buildup and ensuring complete sample recovery.
-
Exceptional Weathering & Aging Resistance: Offers long service life without degradation or yellowing under prolonged exposure.
-
Low Element Blank Values: Ideal for ICP-MS and trace element analysis due to its ultra-low leaching profile.
-
Leak-Proof Solid Stopper: Precision-machined neck and stopper ensure an airtight seal to prevent reagent leakage and evaporation.
Applications:
-
Liquid storage, precise mixing, and transfer of high-purity or highly corrosive chemicals.
-
Trace element and isotope analysis in environmental testing, geochemical laboratories, and semiconductor manufacturing.
-
High-temperature/high-pressure reagent handling without side-reaction risks.
Precautions & Handling:
-
Operating Limits: Do not exceed the maximum recommended temperature (+250°C) or pressure limits to avoid deformation or damage.
-
Cleaning: Ensure thorough cleaning before first use to prevent contamination affecting experimental results.
-
Seal Inspection: Always check the tightness of the stopper when reacting or transferring volatile solutions to prevent leaks.
-
Physical Care: Avoid hard mechanical impacts, drops, or severe vibrations to maintain structural integrity.
