For Routine NMR
Our “Standard Series™” NMR tubes are manufactured out of ASTM Type 1 Class B glass, commonly referred to as N-51A. Applications that are suited for using this type of glass are routine NMR where samples are run under room temperatures with no thermal gradients. It is therefore not recommended to fuse this glass with standard vacuum manifolds and the like, since these are generally made out of Type 1 Class A glass. Each NMR tube is checked for concentricity and camber specifications utilizing the latest computer technology.
For Silicon and Boron NMR, we recommend the use of either TL-5-TUBEKIT for 5mm probes or TL-10-TUBEKIT for 10mm probes. Kit is designed for either Varian, Bruker, or JEOL spinners as a holding device for the fluoropolymer liner. Probe only “sees” fluoropolymer, allowing for excellent 29Si and 11B spectra.
Patented Design Elements Allow Safe & Secure Closure
The standard 5mm and 3mm NMR tube cap designs have existed for decades. Many users can attest to the significant flaws inherent in the traditional NMR tube caps, especially when faced with the chore of capping numerous sample tubes.
NorLoc™ Caps work well with any NMR tube but are best when paired with Secure Series™ NMR sample tubes from Norell®. Internal components of NorLoc™ caps engage with the security band printed on our Secure Series™ NMR tubes and indicate one of two stages of closure.

For High Pressure
Ultimate Protection: Level 3 Level 3 incorporates additional chemical and solvent resistance over Level 1 and the traditional High Pressure Valved NMR Sample tubes, by the substitution of Kalrez® perfluoroelastomer o-ring(s) in place of the standard fluoroelastomer o-rings. Kalrez® perfluoroelastomer o-rings offer the ultimate level of physical and chemical resistance with the inclusion of a secondary, backup o-ring.
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.
The Extreme Series line consists of two categories: Level 1 and Level 3. Both levels incorporate a certain higher degree of valve seal integrity to guard against leakage or pressure loss due to o-ring failure caused by wear or other physical damage, and / or deterioration or damage caused by chemical exposure.
5mm, Standard, Natural Quartz EPR Sample Tubes, 5 Pack Norell EPR tubes produce lower background signals and have better resistance to breakage than competitor brands. Our proprietary technical treatment reduces background noise along with the benefit of protecting against tube breakage.
Additionally, we have designed a new fluoropolymer closure system around our fire-polished tube ends that prevents sample loss during temperature gradients. Available in both standard and ultra precision. Supplied with tapered fluoropolymer caps.
