ReproSil-XR 300 C8 from Dr. Maisch HPLC GmbH is a high-purity silica-based wide-pore HPLC column with a 300 Å pore size and an octyl bonded phase. The medium alkyl chain provides balanced hydrophobic retention, enabling efficient separation of proteins, peptides, and other high-molecular-weight biomolecules while allowing faster elution than C18 phases. The wide-pore design ensures optimal accessibility and efficient mass transfer, making this column ideal for analytical and preparative workflows in proteomics, biopharma, and biomolecule purification.
ReproSil-XR 300 C8 columns from Dr. Maisch HPLC GmbH combine wide-pore accessibility with balanced hydrophobic selectivity – the versatile choice for high-resolution large biomolecule chromatography.
