Corrosion Resistant PFA NMR Tubes with PTFE Caps for High Temperature Trace Analysis Applications

Product Overview

This high-performance sample containment system is engineered for the most demanding analytical environments, specifically where traditional glass or standard polymers fail due to chemical reactivity or thermal limitations. Constructed from premium-grade Perfluoroalkoxy (PFA), these tubes provide an inert, non-contaminating vessel for NMR spectroscopy and trace element analysis. The integration of precision-machined Polytetrafluoroethylene (PTFE) caps ensures a secure, leak-proof seal that maintains sample integrity even when subjected to volatile solvents or aggressive reagents.

Designed for use in sectors ranging from pharmaceutical research to semiconductor manufacturing, the equipment excels in scenarios requiring absolute purity and resistance to hydrofluoric acid, strong alkalis, and concentrated organic solvents. By utilizing advanced fluoropolymer materials, this unit eliminates the risk of ion leaching and sample adsorption, which are critical factors in high-sensitivity spectroscopy. The transparent nature of the PFA body allows for clear visual monitoring of samples, ensuring that reactions or phase changes can be observed in real-time without compromising the containment environment.

Our commitment to engineering excellence ensures that every unit is manufactured to exacting tolerances, providing the reliability and performance consistency required for reproducible scientific results. Whether utilized in routine laboratory workflows or specialized industrial processes, this system represents the pinnacle of fluoropolymer fabrication. Backed by extensive material expertise, we provide these components as customizable solutions, tailored to the specific geometric and functional requirements of sophisticated modern instrumentation.

Key Features

• Exceptional Chemical Inertness: The PFA construction provides near-universal resistance to corrosive chemicals, including aqua regia and hydrofluoric acid, ensuring the vessel does not react with or contaminate the sample.
• Extreme Thermal Stability: This system operates reliably across a vast temperature spectrum, from cryogenic conditions to sustained high-temperature environments reaching 260°C without loss of structural integrity.
• Low Background Noise for NMR: The fluoropolymer material is selected specifically for its low interference properties, making it an ideal choice for sensitive nuclear magnetic resonance applications where purity is paramount.
• Precision-Engineered PTFE Caps: Each unit features a custom-machined cap that provides a high-performance mechanical seal, preventing evaporation and protecting the sample from atmospheric contamination.
• Non-Stick Surface Properties: The ultra-smooth internal finish of the fluoropolymer ensures minimal sample adherence, facilitating complete sample recovery and simplifying the cleaning process for reuse.
• Superior Transparency: High-grade PFA ensures excellent optical clarity, allowing technicians to inspect sample consistency, color changes, or precipitation without opening the vessel.
• High-Purity Manufacturing: Produced in controlled environments to prevent the introduction of trace metal ions or organic impurities, making the equipment suitable for ppt-level analytical work.
• Customizable Dimensions: Beyond standard sizing, these units can be tailored through CNC fabrication to meet specific length, wall thickness, or diameter requirements for non-standard probes.
• Robust Impact Resistance: Unlike traditional quartz or glass tubes, this fluoropolymer unit is highly resistant to mechanical shock and breakage, reducing the risk of hazardous spills and sample loss.
• UV and Radiation Resistance: The material naturally resists degradation from UV exposure and high-energy radiation, maintaining its physical properties and clarity over long-term use in various laboratory conditions.
