Description

Wilmad Precision NMR kvartsrör har en extremt låg termisk expansionshastighet och hög draghållfasthet som är 14 gånger mer robust under kylning/uppvärmningsprocessen än typ 1 klass A glasrör

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
