Vespel® GC Ferrules
Fitinky a konektory
Vespel GC ferrules are made from 100% high-temperature polyimide, a hard polymeric material that tends to seal permanently to capillary columns when in use. A firm torque is required to compress and seal.

  • Made from high temperature Dupont polyimide
  • They are not reusable
  • Vespel tends to shrink through repeated heating and cooling cycles
  • Hardest of the polymeric ferrules so a firm torque is required to compress and seal

They are excellent for creating seals on metal or glass and have long lifetimes. 100% Vespel is essentially non-porous to oxygen so it is ideal for GC/MS interface use, where air permeation can raise the background signal and contribute to phase degradation. They also work best in connections that are isothermal or insulated from oven temperature changes.

These ferrules are rated for use up to 350 °C.
