NMR Tubes by Norell 
Product Details:
We supply a range of NMR and EMR Tubes manufactured by Norell Inc. (USA) who are a known name for innovation when it comes to NMR Tubes. With our rich experience in supplying specialized lamps to reputed companies for more than 25 years, we also excel in providing NMR & EPR Tubes with other accessories by Norell.
Some of the benefits of selecting NMR Tubes under the brand Norell from us are as follows:
NMR tube bottoms are uniformly hemispherical and consistent, thereby minimizing shimming and susceptibility differences among samples.
This uniformity extends throughout the wall thickness of the tubes, maximizing the concentricity among tubes and lots. This translates to the more consistent placement of the contained sample volumes in today’s advanced, highly homogeneous, high field NMR magnets.
NMR tubes are manufactured with round bottoms and are available with flat bottoms upon request.
We also supply all NMR tubes at any length upon request.
We have classified the portfolio of NMR & EPR Tubes supply according to the various purpose.
HIGH-RESOLUTION NMR TUBES
In case of High-Resolution testing purpose, we supply SelectSeries [TM] from Norell. Advantages of choosing High-Resolution NMR Tubes are as follows:
“Select Series” NMR tubes are manufactured out of ASTM Type 1 Class A glass, commonly referred to as Pyrex® 7740 (Corning), Duran® (Schott Glass), or Kimax® KG-33 (Kimble) glass.
Properties that make this glass type desirable for NMR are its high degree of thermal shock resistance and low expansion coefficient.
This allows for a greater margin of safety from breakage when used in variable temperature applications and freeze/thaw cycling, or under any other application where large temperature variations are required in the experiment.
Each NMR tube is checked for concentricity and camber specifications utilizing the latest computer technology.
ROUTINE NMR TUBES
For the routine purpose, we supply “Standard Series” NMR Tubes manufactured by Norell. Some of the noted features of this series are as follows:
“Standard Series” NMR tubes are manufactured out of ASTM Type 1 Class B glass, commonly referred to as N-51A.
Highly 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.
