9197-P - Iso-Prep(tm) Guard Holder 21.2 mm
Iso-Prep Guard Holder is part of a system designed to protect valuable prep columns. Iso-Prep Guard Holder helps in protecting prep columns with no degradation of peak shape or plate count. The high-performance guard protects columns in two ways. First, it acts as a filter, trapping particles in the frits. Second, when the guard cartridge is packed with the same material as the prep column, it removes compounds that irreversibly adsorb to the packing material.
