Sapphire NMR tubes have extraordinary hardness and a high melting temperature around 2000 °C making them ideal for high pressure experiments up to 5801.5 psi.

• Outstanding chemical resistance to corrosive solvents, including HF acid
• Provides zero background in most NMR experiments
• Guaranteed straightness for optimized shimming quality and tested in spinner turbines

Saphire NMR tubes are popular among the following applications: High Pressure NMR up to 5801.5 psi, tube only, no flange supplied; 19F studies, especially studies with HF acid involved; 29Si studies.
