Wilmad Quick Pressure Valve Sample Tubes are specially designed to simplify the work of NMR/EPR studies for catalysis, gas-liquid phase reactions, air sensitive samples and elevated temperature studies using low boiling point solvents. 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..
