Wilmad-LabGlass™ SP Scienceware™ 10mm O.D. Thin Walled Quartz NMR Tube

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

Supplier:  Wilmad-LabGlass™ 664071095

Catalog No. 16-800-423

Description

• Naturally occurring quartz maintains an over 85% transmission rate (10 mm thickness, with consideration of reflection loss) above 265nm that makes quartz tubes preferable in photochemistry studies
• Half the dielectric constant of Borosilicate 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 check
