Description General description Specially designed to simplify the work of NMR scientists performing catalytic, gas-liquid phase reactions, air sensitive samples, and elevated temperature studies using low boiling point solvents and can be used for EPR spectrometry too. The Quick Pressure Valve can also be attached to a quartz sample tube for EPR by using a graded seal that connects the Pyrex portion of the valve to the quartz tube. • Easy to operate - one turn to open, one turn to close • Larger opening for convenient sample addition • Light weight, concentric design for better performance • Unions and fittings for both 1/16 in. and 1/8 in. tubing Linkage For instructions, see Quick Pressure Valve Instructions.
