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.

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.

WG-1000-7 Type 1 Class B Glass Thin Walled NMR Sample Tube, High-Throughput, 5 mm OD x 7" Length (Pack of 100)

Tubes that are 9 in. L are for making standards and for use with tip-off manifolds. Economy and disposable Wilmad NMR tubes are best used for high-throughput NMR spectroscopy.

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 temperature with no thermal gradients.
