Description
The Brownlee conventional column pre-filter and guard column holder systems allow you to select from three different levels of column protection that couple directly to the head of your column. The 10 mm guard cartridge holder with a pre-filter provides the ultimate in column protection with a selectable filter frit for elimination of particulates along with a guard cartridge packed with a selectable stationary phase to protect against compounds that irreversibly absorb onto the stationary phase.
Provides protection against compounds that irreversibly adsorb onto the stationary phase and eliminates particulates.
