Semi Prep HPLC Column, RP C8 Octyl, Wide Pore, 10um, 300A. 10mm ID x 50mm Length. Cogent Brand. 1 EA.
Additional Information:
Cogent RP C8 Octyl Wide Pore is a reversed-phase semi-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 molecules while maintaining the moderate hydrophobicity and selectivity characteristic of C8 chemistry. This stationary phase is well suited for semi-preparative purification workflows where recovery, loading capacity, and efficient fraction collection are critical.
68008-SP50-3M is a semi-preparative HPLC column with dimensions of 10 mm ID x 50 mm length, packed with 10 µm RP C8 Octyl Wide Pore particles featuring a 300 Å pore size. The 10 mm internal diameter provides significantly greater sample loading capacity than analytical columns, while the shorter 50 mm length is optimized for rapid purification cycles, high throughput processing, and efficient method optimization. The 10 µm particle size supports higher flow rates with lower operating backpressure, making this column suitable for purification, method transfer, and scale-up workflows. Typical operating flow rates are approximately 8–15 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, and other large hydrophobic or neutral compounds. The wide pore architecture improves analyte accessibility while supporting efficient purification of higher molecular weight compounds. The shorter column format is often selected when throughput and loading capacity are prioritized over maximum chromatographic resolution. Analytical methods are commonly developed on analytical columns before being transferred and optimized on semi-preparative columns such as this one. A semi-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.
