Ferrules

Ferrules for HPLC and GC

Ferrules are used in chromatography to help prevent leaks. The ferrule forms a strong, permanent, airtight seal around the column. Ferrules for HPLC and GC by well-known manufacturers such as Agilent Technologies, Grace, Upchurch Scientific, Vici Valco and many more are available in our shop.

We have a large selection of high quality ferrules for liquid chromatography (HPLC) and gas chromatography (GC) to ensure optimal separation efficiencies. The choice of which ferrule to use in your system depends on a number of parameters. Tubing size, pressure requirements, connecting nuts and most importantly, the geometry of the connecting ends must be considered when choosing the right ferrule for any given application. Materials such as PEEK, PCTFE and stainless steel are often used to manufacture ferrules for high pressure applications. Softer polymers, including EFTE and polypropylene, are used in lower-pressure applications.
