Ferrules
Ferrules are all thermally conditioned and ready for immediate high temperature GC use. They are available in different materials (100% graphite, 85% Polyimide/15% graphite, 60% Polyimide/40% graphite, 100% Polyimide and 100% Teflon depending on the maximum operating temperatures required and in different format depending on the connection needed.
Choosing the Right Ferrule
All ferrules are thermally conditioned and ready for immediate high temperature GC use.
Advantages of Graphite Ferrules:
Our graphite ferrules fit Swagelok® or Parker® fittings. Graphite ferrules are soft and compliant. They will not stick to glass at higher temperatures. These ferrules are ideal for glass to metal connections. The graphite ferrule can be reused if not over tightened.
Advantages of Polyimide Ferrules:
Improved mixing techniques for polyimide ferrules allow for better homogenous mixing of graphite and polyimide resin. One can observe this when looking at a polyimide ferrule. The surfaces are very smooth and exhibit a highly polished or highly shined surface. Polyimide ferrules exhibit a lower coefficient of expansion than other polyimide resins, therefore, reducing the tendency of the column nuts loosening in the heated GC ovens.
Advantages of PTFE Ferrules:
The PTFE ferrules are a one piece design and require no back ferrule. These ferrules are completely inert.
