Wilmad-LabGlass 10 mm 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 around 1200 ppm and has certain impact on shimming quality at high field over 600 MHz.
10 mm NMR tubes have an averaged camber of 60 micron to gurantee the spectrum reolution for small melecules (MW<500) samples up to 600 MHz. 10 mm Economy tube is ideal for MRI imaging applications. Item is sold in a paper pack of 100. Blue Caps are now included; other colors may be purchased separately.
