Valved NMR Tubes for Vacuum & Reduced Pressure

Valved NMR tubes for vacuum & reduced pressure

NORELL® is proud to introduce the new 3mm valved NMR tubes for vacuum & reduced pressure.

Handle your NMR sample without flame-sealing your tubes. Fluoropolymer covered o-ring eliminates material incompatibilities. Completely greaseless fluoropolymer assembly, which is easy to use and to disassemble for cleaning. Includes female joint for quick attachment to your vacuum rack.

A vacuum level of 10-7 kPa (10-6 torr) can be attained with this valve. While this valve can also withstand an internal positive pressure to 500 kPa (5 bar, 72 psi), the VT Valved NMR Tube series is intended principally for vacuum work. When pressurizing internally (by heating the NMR tube, for instance), the valve must be fully closed, so that the female vacuum adapter joint (the short glass tube that slips over the top of the PTFE valve stem, sealing against the upper o-rings) cannot be used to apply or be exposed to a positive pressure.

The tables on this page present a selection of 3 and 5 mm O.D. NMR tubes joined to the VT style valves. However, other tube diameters, lengths, additional MHz ratings and tube materials (such as quartz), are available. Please feel free to request a quote on your custom requirements, as we are continually striving to provide the utmost service and satisfaction to our customers!
