Wilmad-Lab Glass 513A-3PP-8-5 Borosilicate Glass Thin Walled Precision NMR Tube, 8 mm OD, 8" Length, 300 MHz (Pack of 5)

To maximize snr, precision nmr tubes have minimal paramagnetic impurities that would impact shimming. Tight ID and OD tolerance as small as 0.0065mm accommodates wilmad inserts.

• Manufactured in a state-of-the-art iso 9001:2008 usa facility using a unique precision shrinking and grinding process to shape the inner surface with maximized filling factor
• Inner surface is resistant to strong acid and base at ambient temperature
• Can be operated safely at temperatures up to 230°c, and within a temperature step of 120°c
• Rated as hydrolytic class 1
• Ideal for experiments requiring critical shimming quality (high/ultrahigh field, non-spinning, multi-dimensional, multi-nuclei, dnp experiments and studies involving biological samples)
