Prep Guard Column Cartridge, RP C4 Wide Pore, 5um, 300A. 30mm ID x 10mm Length. Cogent Brand. 1 EA. Special Order Item.
Additional Information:
Cogent RP C4™ Wide Pore Prep Guard Column Cartridges are designed to protect valuable preparative HPLC columns from particulates, sample contaminants, and strongly retained compounds that can reduce column performance and shorten column life. Packed with the same RP C4™ Wide Pore stationary phase used in Cogent preparative columns, these guard cartridges help maintain method consistency while extending preparative column service life. The stationary phase consists of a four-carbon butyl ligand bonded to ultra-high purity silica and is fully double end capped for reproducible reversed-phase performance.
68504-P30-PG1-3 is a preparative guard column cartridge packed with 5 µm RP C4™ Wide Pore particles featuring a 300 Å pore size in a 30 mm ID x 10 mm format. Designed specifically to protect Cogent RP C4™ Wide Pore preparative columns, the cartridge captures particulates and contaminants before they reach the preparative column bed. Constructed from a stainless steel tube with stainless steel frits, it provides durability and reliable performance in demanding preparative HPLC applications.
Routine replacement of guard column cartridges helps maintain preparative column efficiency, preserve chromatographic performance, and reduce operating costs associated with column replacement. This cartridge is ideal for preparative purification of proteins, peptides, enzymes, and other large biomolecules used in pharmaceutical, biopharmaceutical, and research laboratories.
