ReproSil-Pur 300 C4

Wide-Pore Short-Chain Alkyl Column for Proteins and Peptides

ReproSil-Pur 300 C4 is a silica-based HPLC column with butyl bonded chemistry on high-purity 300 Å silica. The wide-pore structure provides excellent accessibility for large biomolecules such as proteins and peptides, while the short-chain alkyl bonding offers reduced hydrophobic retention compared to C8 or C18 phases. This combination enables efficient separations of sensitive biomolecules under milder chromatographic conditions.

The robust bonding chemistry ensures reproducibility, sharp peak shapes, and long operational lifetimes, even under gradient and elevated temperature conditions. ReproSil-Pur 300 C4 is particularly well suited for biopharmaceutical and proteomic laboratories requiring gentle but effective reversed-phase separations.

ReproSil-Pur 300 C4 combines wide-pore accessibility with balanced hydrophobic retention – the reliable choice for laboratories analyzing proteins and peptides by HPLC.
