Try our family of novel low pressure/vacuum tubes for NMR and EPR experiments as an alternative to other similar tubes. A 4X larger sealing surface eliminates leaks and greatly increases its lifetime when compared to traditional gas-tight tubes. It continues to offer a convenient flame-free sealing solution for air sensitive or volatile liquid samples at any pressure from vacuum to pressure slightly above 1 bar.
Greaseless PTFE piston provides a 100 percentage contamination-free seal.
Axial symmetric design guarantees its application in spinning experiments.
