Since 2002, Sepax Technologies, a Delaware US-based company, has been providing cutting edge products and services for liquid chromatography (LC). Sepax specializes in the development and manufacture of LC analytical, preparative and process separation & purification columns, bulk resins and systems in a wide range of modalities, such as SEC, IEX, HIC, Affinity, and RP. Sepax also provides LC services, including analytical testing, method optimization, purification, custom resin development, and ligand immobilization. Certified to ISO 9001:2015 standards, Sepax focuses on customer & market needs, and is continuing to expand its presence and supply chain around the globe in three business platforms: Analytical Chromatography, Industrial Purification and Medical Diagnostics.


As a manufacturer owning core know-how and intellectual properties on chromatography materials science and engineering, Sepax Technologies has developed a wide range of patented and proprietary technologies in the areas of base bead synthesis, surface chemistry and column packing that have established itself as one of the leaders in chromatographic analysis and separation. We serve our customers for analytical to process applications on small molecules to biological macromolecules.

ChromLab is the official distributor for Sepax Technologies in Cyprus , Iraqi Kurdistan , Saudi Arabia , United Arab Emirates , Syria , Lebanon , Oman , Qatar .
