Sigma Aldrich Fine Chemicals Biosciences WilmadR low pressure/vacuu1EA

Novel low pressure/vacuum tube for NMR and EPR spectroscopy. A 4X larger sealing surface eliminates leaks and greatly increases its lifetime when compared to traditional gas-tight tubes. Offers a convenient flame-free sealing SOLUTIONon for air sensitive or volatile liquid samples at any pressure from vacuum to pressure slightly above 1 bar.features Greaseless PTfE piston provides a 100% contamination-free seal. Axial symmetric design guarantees its application in spinning experiments.Economical. reliable CAUTION 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.
