Description
Replacement ferrule > 2 µm for holder 718966 is a specialised PEEK ferrule intended for HPLC columns with particle sizes greater than 2 µm. It is designed for the Column Protection System guard column holder (REF 718966) and provides a dependable seal in analytical chromatography setups using conventional particle packings. The product is supplied as a pack of five pieces, so laboratories can stock consumable fittings for regular maintenance of guard column assemblies that protect analytical columns from particulates and matrix residues. Manufactured from PEEK, the ferrule offers mechanical stability and solvent compatibility suited to everyday HPLC mobile phases and operating conditions. Used with the matching CPS holder from manufacturer Macherey-Nagel, it supports EC-format guard columns as part of the Column Protection System. Keeping dedicated ferrules for packings above 2 µm helps maintain leak-free connections and consistent system performance during method work. Installation is straightforward alongside the holder’s capillaries and tools, making this pack a practical spare for chromatography laboratories performing routine guard cartridge changes.
