SP Wilmad-LabGlass 5 mm Precision NMR Sample Tube Low Pressure/Vacuum Valve (LPV) 7" L , 500MHz

Wilmad’s low pressure/vacuum (LPV) tube is ideal for anaerobic and gas-tight NMR experiments, and offers a convenient flame-free sealing solution for air sensitive or volatile liquid samples.

• Robust sealing system allows pressure buildup inside the sample
• Greaseless PTFE piston provides a 100% contaminationfree seal
• Redesigned with a 4X larger sealing surface, eliminating leaks and greatly increasing lifetime when compared to traditional JYoung tubes
• Axial symmetric design guarantees application in spinning experiments
• Due to the nature of glass, Extreme Caution should be exercised when using at elevated or reduced pressures since a tiny scratch on the glass surface would significantly lower the tensile strength. Adequate safety shielding should always be used when working in these conditions.
