    Membrane Adsorber

    for biomolecule purification with i3 Digital Membrane Chromatography

    The i3 Digital Membrane Chromatography Adsorber is designed for the efficient and gentle purification of biomolecules using the DMC-elution method.

    • Ideal for rapid capture and release of highly concentrated biomolecules, monoclonal antibodies and Fc-containing molecules

    • Enables work in small-scale applications such as research, screening and process development

    Its charged surface enhances the binding and separation process, providing rapid purification without compromising the integrity of your samples via DMC. Featuring an integrated ultra-thin gold membrane and contact pins on the housing, this advanced design allows for precise application of an electric field via the i3 DMControl Smart Control Unit. This ensures optimal control over the elution process, enhancing both performance and consistency.

    The Membrane Adsorber is equipped with Luer-Lock connectors for seamless integration with liquid chromatography (LC) systems, making it easy to incorporate into your existing workflows for maximum convenience and flexibility.

    Visit Shop

    The i3 DMCPrA is intended for the affinity purification of monoclonal antibodies and Fc-containing molecules using electrical potential for elution. It enables a rapid purification of highly concentrated eluates for drug discovery applications and in the productions of biomolecules for research and development.

    • Rapid and gentle purification on mAbs and Fc-containing proteins

    • Highly concentrated eluates without aggreration through multiple elution cycles

    • Easy connection to peristatic pumps or chromatographic systems

    • No buffer exchange
