Prep HPLC Column, RP C8 Octyl, Wide Pore, 10um, 300A. 21.2mm ID x 250mm Length. Cogent Brand. 1 EA.
Additional Information:
Cogent RP C8 Octyl Wide Pore is a reversed-phase preparative HPLC stationary phase manufactured using high-purity silica with traditional octyl (C8) silane bonding and complete double endcapping. The 300 Å pore structure is specifically designed to improve accessibility for proteins, peptides, and other large biomolecules while maintaining the moderate hydrophobicity and selectivity characteristic of C8 chemistry. This stationary phase is well suited for preparative purification workflows where recovery, loading capacity, and efficient fraction collection are critical.
68008-P21-2503M is a preparative HPLC column with dimensions of 21.2 mm ID x 250 mm length, packed with 10 µm RP C8 Octyl Wide Pore particles featuring a 300 Å pore size. The large internal diameter provides substantial sample loading capacity, while the extended 250 mm length delivers increased resolving power and peak capacity for demanding purification applications. The 10 µm particle size supports higher flow rates with lower operating backpressure, making this column suitable for purification, process development, and preparative scale-up workflows. Typical operating flow rates are approximately 15–40 mL/min depending on sample load, mobile phase composition, and system capabilities.
Designed for purification and fraction collection rather than routine analytical HPLC, this column is particularly useful for proteins, peptides, enzymes, and other large hydrophobic or neutral biomolecules. The longer column bed helps improve separation of closely related compounds and can enhance purity during preparative isolations. Analytical methods are typically developed on analytical columns before transfer and optimization on preparative columns such as this one. A specialized preparative HPLC system capable of higher flow rates, larger injection volumes, and fraction collection is required. This product is supplied as a Special Order Item manufactured specifically upon receipt of order.
