NMR Tubes

Wilmad-LabGlass Economy NMR Tubes are manufactured from borosilicate glass that meets the ASTM Type 1 Class B standard and recognized as N51A. Due to its nature, this glass has much less thermal-shock resistance than Class A glass used for our Precision Tubes. It may contain Fe₂O₃ which is paramagnetic (1200 ppm) and has certain impact on shimming quality depending on the magnetic field strength.

Economy tubes are recommended only for experiments with small organic molecule (Molecular Weight ~500) at ambient temperature only. The camber and concentricy listed in the product specification table is the upper limit value.

Each tube comes with a disposable cap.
