Cole-Parmer Direct-Connect Guard Cartridge Holder; 1/Ea

Cole-Parmer® guards and filters are designed to ensure that erroneous materials do not find their way into the more important and expensive analytical column.

The direct-connect guard cartridge holder allows for quick replacement of guard cartridges, cartridges sold separately. The guard cartridge system adds sufficient protection to the system without changing retention or selectivity parameters.

An alternative to a guard cartridge system is an in-line filter. These filters have a fingertight direct connection design and are placed between the column and the fitting to trap particulate matter before it reaches the analytical column.

Cartridge holder is required to use guard cartridges. The holder sits just before the column and comes with a fitting that screws into the column. Cartridges are quick to replace, minimizing downtime.
