Wilmad-LabGlass™ SP Scienceware™ 5mm O.D. Thin Walled Quartz NMR Tube

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
