Description
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)
- 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)
