GC septa, ferrules & fittings

GC septa, ferrules & fittings are the consumable seals for a gas chromatograph injector and column connections. GC analysts in environmental, food, petrochemical and pharmaceutical laboratories replace them on a routine schedule to protect peak shape and reduce leaks.

The 31 products listed here are from Macherey-Nagel. Soft silicone septa in N 9, N 11, N 12 and N 13 sizes, 3 mm thick and supplied in packs of 50, are among the listings, with ferrules and fittings for column and inlet connections making up the rest of the section.

Pick a septum by the diameter the injector or cap requires and consider softness against the number of injections it must withstand before replacement. For ferrules, the column outer diameter and the fitting type decide the part. Lancetech Limited can quote GC consumables on request and answer questions on matching parts to your instrument.
