NORELL® is proud to introduce the 3mm & 5mm 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 adjoining tables present a selection of 3mm and 5mm O.D. NMR tubes joined to the VT style valves. However, other tube diameters, lengths (such as 133mm for automated sampling), 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! Now available with Ultra-Thin wall NMR tubes.
Due to the hand crafted nature of our pressure valves overall valve assembly length can vary slightly. A typical variance is 1-2mm. Overall length is based on a fully seated operating cap.

We are delighted to present the Extreme Series line of High Pressure Valved NMR Sample Tubes. The Extreme Series remains similar in function, use and pressure capability to the traditional High Pressure Valved NMR Sample Tubes, but the PTFE fluoropolymer valve plug has been upgraded and improved by changes to the design of the o-ring seal.
