INSTRUMENT SUPPLIES

Ferrules

*For micropacked columns.

**For 0.28 mm MXT columns.

Capillary Ferrules

for

-Inch Compression-Type Fittings

Available in Vespel®, graphite, or Vespel®/graphite material.

Vespel® Ferrules

• 100% high-temperature polyimide.

• Stable to 350 °C.

• Durable, leak-tight.

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

• VG2, 60% Vespel®/40% graphite blend offers the best combination of sealing and

ease of workability.

• VG1, 85% Vespel®/15% graphite blend offers equivalent composition to Agilent

Vespel®/graphite ferrules.

• Seal with minimal torque, reusable, and preferred for vacuum and high-pressure

uses.

• Stable to 400 °C.

• Recommended for mass spec transfer lines.

Encapsulated Ferrules

for

-Inch Compression Fittings

• Reusable—will not deform and stick in fittings.

• Less torque needed to seal ferrule.

• Restek’s unique blend of graphite minimizes fragmentation and out-gassing.

tech tip

Choosing the Right Ferrule

Graphite ferrules are soft, easy to seal, stable

to 450 °C, and contain no binders that might

off-gas. Vespel®/graphite ferrules work better

for vacuum and high-pressure applications

(e.g., GC-MS) because they will not fragment

or allow oxygen to permeate into the system,

whereas graphite ferrules will. Because

Vespel®/graphite ferrules are made from

a harder material, they might require retight-

ening after several temperature cycles.
