Preparative Columns: C8 200A* are optimized for large-scale purification of medium to large-sized molecules using reversed-phase HPLC. With a C8 (octyl) bonded phase and a 200Å pore size, these columns offer balanced hydrophobic interaction and enhanced mass transfer, making them ideal for peptides, natural products, and other moderately hydrophobic compounds. The 200Å pore structure supports better accessibility for larger analytes, ensuring high loading capacity, efficient separation, and consistent performance. Suitable for pharmaceutical and biotech preparative workflows, these columns deliver reproducible and reliable results.
