Product Details
Committed to providing customers with cost-effective NMR consumables of the highest quality, 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 Precision Tubes. It may contain Fe2O3, which is paramagnetic (1200 ppm) and has a certain impact on shimming quality depending on the magnetic field strength. Economy tubes are recommended only for experiments with small organic molecules (molecular weight ~500) at ambient temperature only. 5 mm outer diameter.
