An NMR tube is a thin glass walled tube used to contain samples in nuclear magnetic resonance spectroscopy. Typically NMR tubes come in 5 mm diameters but 10 mm and 3 mm samples are known.

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.

Advance to the next level of sample security, personal safety and time savings. Combine Norell® NorLoc™ II Security Caps™ with Norell® Secure Series™ NMR tubes and experience the ultimate sample containment system. The standard 5mm and 3mm NMR tube cap designs have existed for decades.

High-Throughput NMR Tube and Cap, 4.94665 mm OD x 7" L, Large Marking Spot; 100/Pk

Manufactured out of ASTM Type 1 Class B glass, or commonly referred to as N-51A, these NMR tubes are designed for auto-sampling systems and high-throughput NMR spectroscopy. NMR tube bottoms are uniformly hemispherical and consistent. Suitable for routine NMR. Ideal at room temperatures with no thermal gradients.

The purpose of an NMR tube is to confine a liquid sample in a perfectly cylindrical volume in a magnetic field while being spun at 25Hz. Since this description is based on mechanics, it is not surprising that NMR tubes have been described by structural parameters for many years.
