Low Pressure Vacuum Tubes (LPV)
Low Pressure/Vacuum Tubes
Wilmad Labglass 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 build-up inside the sample
- Greaseless PTFE piston provides a 100% contamination-free seal
- Redesigned with a 4X larger sealing surface; eliminates leaks and greatly increases lifetime when compared to traditional J. Young 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.
