Description

Includes

Tube and disposable cap

To maximize SNR, Precision NMR Tubes have minimal paramagnetic impurities that would impact shimming. Tight ID and OD tolerance as small as 0.0065mm accommodates Wilmad inserts

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.
  • Inner surface is resistant to strong acid and base at ambient temperature
  • Can be operated safely at temperatures up to 230°C, and within a temperature step of 120°C
  • Rated as hydrolytic class 1
  • Made from borosilicate glass that meets the requirement of Type 1 Class A glass from ASTM E438 100% inspection with multiple NIST traceable gauges and optical surface defect checks
