Wilmad’s Pressure Vacuum Tube is the most reliable NMR tube on the market for medium range pressure (<300 psi) and ultra vacuum (10-8 torr) experiments.
- Connect to a 1/8" metal (SST or brass) vacuum line using Swagelok® fittings
- Pressure vacuum valve is made of PTFE, all other parts are Pyrex® or equivalent
Due to the nature of glass, Extreme Caution should be exercised when using at elevated or reduced pressures as performance of tubes under pressure or vacuum cannot be guaranteed. Adequate safety shielding should always be used when working in these conditions.
