High Purity PFA NMR Sample Tubes with PTFE Caps Corrosion Resistant Fluoropolymer Labware

Product Overview

This high-performance laboratory system consists of ultra-pure PFA sample tubes paired with precision-engineered PTFE caps, specifically designed for Nuclear Magnetic Resonance (NMR) spectroscopy and trace analysis applications. By utilizing premium fluoropolymer materials, this unit provides an inert environment that eliminates the risk of sample contamination and background interference common with lower-grade materials. The equipment serves as a critical component for researchers and technicians who require absolute chemical purity and structural integrity during complex analytical processes.

The system is primarily utilized in sectors such as pharmaceutical development, semiconductor manufacturing, and advanced petrochemical research, where aggressive reagents and high-temperature conditions are standard. The choice of perfluoroalkoxy (PFA) for the tube body ensures optical clarity and mechanical resilience, while the polytetrafluoroethylene (PTFE) cap offers a robust, leak-proof seal that resists even the most volatile organic solvents and strong acids. This combination delivers a high level of reliability for critical sample preparation and storage.

Built to withstand the rigors of industrial lab environments, this unit maintains its physical properties across a vast temperature spectrum. Procurement teams and laboratory managers can rely on this system for consistent performance in high-stakes testing, knowing that the materials used are specifically selected for their low-leachable profiles and exceptional thermal stability. Each component is manufactured with a focus on precision, ensuring that the assembly fits seamlessly into standard and custom analytical instruments.

Key Features

• Ultra-High Purity Material Construction: The use of high-grade PFA ensures that these tubes possess an exceptionally smooth surface finish and minimal metallic ion content, which is vital for maintaining the integrity of sensitive trace analysis samples.
• Superior Chemical Inertness: Both the PFA tube and PTFE cap are virtually immune to chemical attack, providing reliable performance when handling concentrated hydrofluoric acid, aqua regia, and other aggressive substances that would degrade glass or standard plastics.
• Exceptional Thermal Stability: Engineered to operate efficiently at temperatures up to 260°C (500°F), this system allows for high-temperature NMR studies and heated sample digestion without the risk of structural deformation or material degradation.
• Precision-Machined Sealing Caps: Each PTFE cap is fabricated via high-precision CNC machining to ensure a tight, interference-fit seal, preventing sample evaporation and protecting the environment from hazardous fumes.
• Low Background Interference: The inherent properties of PFA minimize background signals in NMR spectroscopy, allowing for higher resolution and more accurate data acquisition in structural elucidation experiments.
• Non-Stick Surface Properties: The hydrophobic and oleophobic nature of the fluoropolymer materials ensures maximum sample recovery and simplifies the cleaning process, reducing the risk of cross-contamination between batches.
• Robust Durability: Unlike fragile glass alternatives, these fluoropolymer tubes are shatter-resistant and highly durable, providing a safer working environment and reducing long-term replacement costs in high-throughput laboratories.
• Full Customization Potential: This system can be tailored to meet specific experimental requirements, with bespoke dimensions, wall thicknesses, and cap configurations available to match non-standard probe sizes or unique workflow needs.
