NMR Tubes
WilMad LabglassTM NMR Tubes
Committed to providing customers with cost­effective NMR consum­ ables of the highest quality, Wilmad­LabGlass 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 thermal­shock 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.

    Use a Mortar
and Pestle Safely
• Both before and after grinding a sample, clean and dry the mortar and pestle thoroughly.
• Never grind two materials together without first determining if it is safe. Consult the chemicals’ hazard alerts, Safety Data Sheets and safety handbooks prior to use.
• Explosions have resulted when the two previous rules were not observed.
 A “Never”!
NEVER grind a strong oxidizing agent (like potassium chlorate) together with a strong reducing agent because what may result is a highly exothermic reaction. We repeat, NEVER grind potassium chlorate with anything! If mixing is required, grind the substances separately and then gently mix, using a glass stirring rod.
