NMR Tubes with PTFE Valve – for Air-Sensitive Samples under Inert Conditions
Our NMR tubes with integrated PTFE (Teflon) valve offer a safe and convenient solution for sample preparation under inert atmosphere – without the need for flame sealing.
Ideal for use in organic chemistry, catalysis research, materials science, and wherever samples must be prepared under inert gas or vacuum conditions.
- Safe Handling under Protective Atmosphere: The high-quality PTFE valve enables precise filling, evacuation, and airtight sealing – perfect for handling air-sensitive compounds.
- Vacuum-Compatible: The glass adapter allows easy connection to vacuum systems for controlled processing under reduced pressure.
- Chemically Resistant & Gentle on Materials: The Teflon-coated O-ring prevents unwanted reactions with solvents, ensuring maximum chemical compatibility and safety.
- Easy to Clean & Reusable: The grease-free valve assembly is easy to disassemble and clean – ideal for repeated use in everyday lab routines.
- Compatible with Autosamplers: Also available in a shortened version suitable for common NMR autosamplers – enabling automated NMR measurements under inert conditions without manual handling.
- Custom Versions Available: In addition to standard sizes, we offer customized variants with special lengths or specifications. Feel free to contact us!
