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

  • 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
