Equisil

Versatile HPLC Column Series for Reliable Reversed-Phase Chromatography

Equisil is a flexible HPLC column series based on fully porous, high-purity silica, designed for routine reversed-phase applications across a wide range of industries. With commonly used bonded phases such as C18, C8, and phenyl, Equisil columns offer reliable retention, reproducible peak shape, and broad chemical compatibility. They are well suited for quality control, method development, and general-purpose separations in pharmaceutical, food, environmental, and academic laboratories.

Equisil columns combine versatility and reliability – ideal for laboratories looking for consistent reversed-phase performance at a practical value.
