EcoPrep 120 Si

Preparative Unmodified Silica Column for Normal-Phase Chromatography

EcoPrep 120 Si is a preparative HPLC column packed with fully porous, high-purity silica featuring a 120 Å pore size and an unmodified surface, ideal for normal-phase and adsorption chromatography. Designed for the purification of small to medium-sized polar compounds, this column offers strong silanol-based interactions, high sample capacity, and robust mechanical stability for cost-efficient compound isolation.

EcoPrep 120 Si provides reliable normal-phase selectivity and scale-up performance – a robust solution for preparative polar compound purification.

Key Features

  • Bare silica phase (USP L3) with 120 Å pore diameter

  • Optimized for normal-phase and adsorption separations

  • Strong retention of polar and isomeric compounds

  • Fully porous silica with high surface activity and loading capacity

  • Suitable for preparative flow rates and 10 µm particle sizes

Typical Applications

  • Normal-phase purification of polar organic compounds

  • Fractionation of isomers, natural products, and plant extracts

  • Dry-loading and non-aqueous separations

  • Scalable compound isolation in chemical and pharmaceutical workflows
