Prep HPLC Column, RP C4, Wide Pore, 5um, 300A. 30mm ID x 100mm 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 large biomolecules while maintaining the reduced hydrophobic retention characteristics of C4 chemistry. The wide pore design is particularly beneficial for preparative bioseparations where recovery, loading capacity, and chromatographic efficiency are critical.
68504-P30-1003M is a preparative HPLC column packed with 5 µm RP C4™ Wide Pore particles featuring a 300 Å pore size in a 30 mm ID x 100 mm format. The large internal diameter provides exceptional sample loading capacity for purification applications, while the 100 mm length offers an excellent balance between throughput and chromatographic resolution. The 300 Å pore structure improves accessibility and mass transfer for proteins, peptides, enzymes, and other large biomolecules. Typical operating flow rates are approximately 30–60 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 30 mm ID format provides higher loading capacity than smaller preparative columns and is ideal for demanding purification workflows. A specialized preparative HPLC system is required for operation.
