Equisorb

Versatile and Economical HPLC Columns for Polar and Normal-Phase Chromatography

Equisorb is a cost-effective HPLC column series based on fully porous, high-purity silica, designed for normal-phase, polar interaction, and dual-mode chromatography. With functional options such as C1, C6, C8, C18, CN, NH2, Phenyl, SAX, SCX, and bare silica (Si), Equisorb columns offer flexible selectivity and are well suited for method development, routine polar separations, and training laboratories. These columns deliver reliable retention, reproducibility, and compatibility with both non-polar and polar solvent systems.

Equisorb columns provide practical performance for laboratories requiring flexible, polar-selective chromatography – an economical choice for standard and exploratory HPLC methods.

Good alternative to Spherisorb (Waters™).
