SP Wilmad-LabGlass 3 mm Thin Wall Precision NMR Sample Tube 7" L, 600MHz

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 stateof-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, nonspinning, multi-dimensional, multi-nuclei, DNP experiments and studies involving biological samples)
• Made from borosilicate glass that meets the requirement of Type 1 Class A glass from ASTM E438
• 100% inspection with multiple NIST traceable gauges and optical surface defect checks
• Include disposable cap

Note: Caps are not recommended for use with samples dissolved in chloroform-d or acetone-d6.
