ReproSil-Pur 300 Si

Wide-Pore Silica HPLC Column for Normal-Phase Separations of Large Biomolecules

ReproSil-Pur 300 Si is an unbonded, high-purity silica HPLC column with a 300 Å wide-pore structure, optimized for normal-phase and adsorption chromatography of proteins, peptides, nucleic acids, and other large biomolecules. The large pore size ensures excellent accessibility to the silica surface, enabling efficient interactions even with high-molecular-weight analytes.

With its active silanol groups, ReproSil-Pur 300 Si provides strong polar retention and selectivity, while the high-purity silica minimizes secondary interactions, delivering sharp peak shapes and reproducible results. It is ideally suited for laboratories requiring robust and reliable normal-phase separations of biomolecules.

ReproSil-Pur 300 Si combines ultra-pure wide-pore silica with strong polar selectivity – the dependable choice for laboratories performing normal-phase HPLC separations of large biomolecules.
