Description

Wilmad Precision NMR Quartz Tubes have an extremely low thermal expansion rate and high tensile strength which is 14 times more robust during the cooling/heating process than Type 1 Class A glass tubes

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.

• Naturally occurring quartz maintains an over 85% transmission rate (10mm thickness, with consideration of reflection loss) above 265nm that makes quartz tubes preferable in photochemistry studies
• Half the dielectric constant of Pyrextrademark (TM) glass helps improve the quality factor
• Low Boron density at or below 0.1 ppm guarantees a clean background in Boron-11 NMR studies
• Tight I.D. and O.D. tolerance as small as 0.0065mm accommodates Wilmad inserts
• To maximize SNR, Precision NMR Quartz Tubes have minimal paramagnetic impurities that would impact shimming
• Inner surface is resistant to strong acid and base at ambient temperature
• 100% inspection with multiple NIST traceable gauges and optical surface defect checks
