Prosphere 300 C18

Wide-Pore HPLC Column for Robust Protein and Peptide Analysis

Prosphere 300 C18 is a silica-based HPLC column with an octadecyl bonded phase on wide-pore (300 Å) silica, specifically designed for the separation of peptides, proteins, and other biomacromolecules. The long C18 chains provide strong hydrophobic retention, ensuring reproducibility, sharp peak shapes, and reliable performance for large analytes.

The wide-pore structure offers excellent accessibility for high-molecular-weight compounds, while robust bonding chemistry ensures long operational lifetimes under routine and demanding chromatographic conditions. Prosphere 300 C18 is the standard choice for laboratories performing biomolecular reversed-phase separations.

Prosphere 300 C18 delivers strong hydrophobic retention with wide-pore accessibility – the dependable choice for laboratories analyzing proteins, peptides, and biomolecules in HPLC.
