Prep HPLC Column, RP C4, Wide Pore, 5um, 300A. 21.2mm ID x 150mm Length. Cogent Brand. 1 EA. Special Order Item.
Additional Information:
Cogent RP C4™ Wide Pore is a reversed-phase HPLC stationary phase designed for the purification and isolation of proteins, peptides, enzymes, and other large hydrophobic or neutral compounds. Manufactured using a four-carbon butyl ligand bonded to ultra-high purity silica and fully double end capped, this 300 Å wide pore stationary phase provides enhanced accessibility for larger biomolecules while maintaining the reduced hydrophobic retention characteristics of C4 chemistry. The wide pore architecture makes this phase particularly valuable for preparative bioseparations and biomolecule purification.
68504-P21-1503M is a preparative HPLC column packed with 5 µm RP C4™ Wide Pore particles featuring a 300 Å pore size in a 21.2 mm ID x 150 mm format. The large internal diameter provides substantial sample loading capacity, while the increased 150 mm column length delivers enhanced resolution and peak capacity compared to shorter preparative columns. The 300 Å pore structure improves accessibility and mass transfer for proteins, peptides, enzymes, and other large biomolecules. Typical operating flow rates are approximately 15–30 mL/min depending on analyte characteristics, mobile phase composition, and system capabilities.
This column is particularly useful for the purification of proteins, peptides, enzymes, and other large biomolecules in pharmaceutical, biopharmaceutical, and research laboratories. Compared to more hydrophobic C8 and C18 phases, the C4 bonded phase generally provides lower retention, which can improve recovery and purification efficiency for larger analytes. The 21.2 mm ID format is ideal for preparative applications requiring high loading capacity and efficient fraction collection. A specialized preparative HPLC system is required for operation.
