Semi Prep HPLC Column, RP C8 Octyl, Wide Pore, 10um, 300A. 10mm ID x 100mm 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-SP100-3M is a semi-preparative HPLC column with dimensions of 10 mm ID x 100 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 100 mm length offers an effective balance between purification efficiency and throughput. 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. 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.
