5 mm Thin Wall Precision Suprasil NMR Sample Tube 9 L, 300M

Wilmad Precision NMR Suprasil® (Synthetic Quartz) Tubes are manufactured from high purity synthetic fused silica materials with <0.005ppm Fe2O3 and outstanding optical characteristics in the deep UV to the near IR. Transmission rate from 190nm to 2600nm is well over 95% (10mm thickness) excluding reflection Possesses a similar thermal expansion rate and tensile strength as natural quartz which is 14 times more robust during the cooling/heating process than Type 1 Class A glass Tight ID and OD tolerance as small as 0.0065mm accommodates Wilmad inserts To maximize SNR, Wilmad Precision NMR Suprasil® Tubes have minimal paramagnetic impurities that would impact shimming 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 Ideal for photolysis experiments that employ 266nm light from a Q-Switched laser or 254nm light emitted by a mercury low pressure lamp with a Schott UG 5 filter, as well as variable temperature experiments that have a temperature step over 120°C Safe for experiments at temperatures up to 1300°C 100% inspection with multiple NIST traceable gauges and optical surface defect checks Includes disposable cap Note: Caps are not recommended for use with samples dissolved in chloroform-d or acetone-d6.
