Reducing Ferrules

Graphite Ferrules

• Preconditioned to eliminate out-gassing
• High-purity, high-density graphite
• Smoother surface and cleaner edges than conventional graphite ferrules
• Contain no binders that can off-gas or adsorb analytes
• Stable to 450°C

Vespel/Graphite Ferrules

• 60%/40% Vespel/Graphite blend offers the best combination of sealing and ease of workability
• Seal with minimal torque, reusable and preferred for vacuum and high-pressure uses
• Recommended for mass spec transfer lines
• Stable to 400°C
