Equisil is a group of reversed-phase HPLC columns built on fully porous, high-purity silica, designed to deliver consistent performance and broad applicability in routine analytical workflows. With a variety of bonded phases such as C18, C8, and phenyl, Equisil columns provide stable retention, reproducible peak shape, and compatibility with aqueous-organic mobile phases. They are well suited for use in pharmaceutical, food, environmental, and academic laboratories.
Equisil columns offer a dependable platform for everyday reversed-phase HPLC – a practical solution for labs requiring reproducibility and flexibility in their chromatographic methods.
