Wilmad^® NMR tubes 5 mm diam., high throughput

High throughput 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 around 1200 ppm and has certain impact on shimming quality at high field over 600 MHz.

High Throughput NMR tubes have an averaged camber of 60 micron to guarantee the spectrum resolution for small molecules (MW<250) samples up to 600 MHz.
