5 mm High Throughput NMR Tube, 4" - Pack of 100 without caps

Wilmad-LabGlass 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 precision NMR 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 microns to guarantee the spectrum resolution for small molecule (MW<250) samples up to 600 MHz.
