      Product introduction

      4B is suitable for components separation and moderate purification of biological macromolecules (remove the small molecular weight impurities), such as virus, macromolecule proteins, superhelix DNA, polysaccharide and macromolecular complex.



      1. High (physical and chemical) stability, high flow rate (component separation), high recovery rate (up to 95%).

      2. The moderate elution conditions can completely preserve the biological activity and function of biological macromolecules.

      3. Easy to be implemented.

      4. Easy to maintain.
