Equisil ODS

Classical C18 Reversed-Phase Column for Routine HPLC Applications

Equisil ODS is a reversed-phase HPLC column based on fully porous, high-purity silica, bonded with octadecylsilane (C18) groups for strong hydrophobic retention. As a classic ODS (octadecylsilane) phase, this column provides reliable performance, stable retention, and good peak shape, making it ideal for routine reversed-phase separations of non-polar and moderately polar compounds in pharmaceutical, food, and environmental analysis. Equisil ODS is a dependable solution for laboratories requiring consistent results in everyday HPLC workflows.

Equisil ODS offers classical C18 reversed-phase performance – a solid choice for consistent, cost-effective analytical separations.
