Prosphere 300 C8

Wide-Pore HPLC Column for Balanced Protein and Peptide Separations

Prosphere 300 C8 is a silica-based HPLC column with an octyl bonded phase on wide-pore (300 Å) silica, developed for the analysis of peptides, proteins, and other biomacromolecules. The medium hydrophobic retention of the C8 chains provides a balance between the strong retention of C18 and the milder interactions of C4 phases, offering versatile selectivity for complex biomolecular samples.

The wide-pore structure ensures accessibility for high-molecular-weight analytes, while robust bonding chemistry delivers sharp peak shapes, reproducibility, and long operational lifetimes. Prosphere 300 C8 is particularly suited for biopharmaceutical and proteomic laboratories where balanced retention and reliability are essential.

Prosphere 300 C8 provides balanced retention with wide-pore accessibility – the dependable choice for laboratories analyzing peptides, proteins, and biomolecules in HPLC.
