Description

Made of high-purity materials that will not contribute background impurities for sensitive and selective detectors; designed to seat securely in a variety of chromatography tube and pipe fittings

For 1/16, 1/8, and 1/4 in. fittings.

100% Graphite ferrules

  • High-density and contain no binders that can off-gas or absorb analytes
  • With a smoother surface and cleaner edges than conventional graphite ferrules
  • Ferrules are very soft and can be easily deformed for an effective seal with fused silica or glass columns
  • Stable to 450°C (842°F)
Vespel™/Graphite ferrules
  • 60%/40% blend, offering the best combination of sealing performance and ease of workability
  • Seal with minimal torque and are preferred for vacuum and high-pressure uses such as GC/MS or other oxygen-sensitive detectors
  • Hard material does not deform easily and may require retightening after several temperature cycles
  • Reusable
  • Stable to 400°C (752°F)
