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 I.D. and O.D. 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 9001:2015 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.
