SP Wilmad-LabGlass Low Pressure Vacuum NMR Tubes, SP Industries

About this item

Ideal for anaerobic and gas-tight NMR experiments, 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 4× larger sealing surface; eliminates leaks and greatly increases lifetime when compared to traditional J. Young tubes
Axial symmetric design guarantees application in spinning experiments

Caution: 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.
