NMR Tubes
Thin, glass tubes of different lengths, wall thicknesses, outer diameters, cambers, concentricities, and I.D. and O.D. tolerances designed to hold samples during nuclear magnetic resonance spectroscopic analysis; may include tube cap.NMR tubes are required for analyzing samples using nuclear magnetic resonance spectroscopy. Choose an NMR tube that most closely matches the frequency (MHz) of your spectrometer.
Typically made of borosilicate glass and offered in seven- and eight-inch lengths, the outer diameter of the tube can range from 3mm to 10mm, with 5mm being the most common. For greater testing precision, look for thin-walled NMR tubes. Quartz NMR tubes with low boron concentrations of boron are also available if boron NMR is used.
NMR tubes are available in reusable or disposable versions. Some versions have screw caps, with or without septa. Polyethylene caps are the most common.
Specifications for NMR tubes may include concentricity and camber.
- Concentricity is how round the tube is and is measured using the inner and outer walls
- Camber is a measure of the tube’s straightness; poor camber can cause the tube to wobble during rotation, which can produce spinning side bands
Nuclear magnetic resonance spectroscopy allows you to observe the local magnetic fields around atomic nuclei. As radio waves excite the nuclei, their resonance is detected by a sensitive radio receiver that provides information about the molecule’s electronic structure. NMR spectroscopy is also used to identify monomolecular organic compounds, proteins, and other complex molecules.
Chemglass Life Sciences Tube, NMR, 5mm, Select Series™, With Caps, 7"" Long, 400 MHz, Concentricity 0.0070mm, Camber 0.0190mm
Tube, NMR, 5mm, Select Series™, With Caps, 7" Long, 400 MHz, Concentricity 0.0070mm, Camber 0.0190mm. NORELL™ Select Series™ NMR Tubes are specifically designed for high-resolution NMR. These tubes are manufactured out of ASTM Type 1 Class A glass, commonly referred to as Pyrex 7740 (Corning), Duran, or Kimax (Kimble) KG-33 glass. Several key 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 any other application where large temperature variations are required in the experiment.

Chemglass Life Sciences Tube, NMR, 5mm, Standard Series™, With Caps, 7" Long, 300 MHz, Concentricity ± 0.010mm, Camber ± 0.038mm
Tube, NMR, 5mm, Standard Series™, With Caps, 7" Long, 300 MHz, Concentricity ± 0.010mm, Camber ± 0.038mm. NORELL™ 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, for auto-sampling systems or high throughput NMR. Redesigned from the ground up and with emphasis on quality and precision, Norell™ has succeeded in virtually eliminating tube wall and bottom variation. It is not recommended to fuse this glass with standard vacuum manifolds and like, since they are generally made of Type 1 Class A glass.
