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, 8" Long, 500 MHz, Concentricity +- 0.0050mm, Camber +- 0.0130mm
Tube, NMR, 5mm, Select Series, With Caps, 8" Long, 500 MHz, Concentricity 0.0050mm, Camber 0.0130mm. 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.

Norell Inc 5mm, 600MHz 7" EXTREME SERIES LEVEL 3 VALVED THIN WALL NMR TUBE FOR HIGH PRESSURE, 1 TUBE PER PACK
Level 1 includes an additional fluoroelastomer o-ring seal to augment the existing fluoroelastomer o-ring, thus providing a secondary, backup o-ring if the primary one leaks or fails because of wear or physical damage. Level 3 incorporate additional chemical and solvent resistance over Level 1 by the substitution of Kalrez perfluoroelastomer o-ring(s) in place of the fluoroelastomer o-rings. Kalrez perfluoroelastomer is made from tetrafluoroethylene, and is virtually chemically identical to PTFE fluoropolymer, but physically Kalrez behaves as an elastomeric material, unlike PTFE. Kalrez furnishes the same unsurpassed chemical resistance and degree of inertness as that of PTFE, while affording a higher service temperature limit (up to 288°C compared to 260°C for PTFE) and no propensity to cold flow (or distort under a constant mechanical force or pressure).
