SorbaDex™ – For the Separation of Biomolecules

SorbaDex (also known as Cytiva Sephadex) is a beaded composite material made with ultrapure cross-linked dextran. It has good selectivity, excellent resolution, minimal non-specific adsorption, and excellent chemical stability. The effects of buffer and pH on resolution are minimal.

Superior performance, cost-effective replacement forCytiva Sephadex^™

One of the major advantages of SorbaDex is its ability to quickly remove small molecules and desalt the sample into pure water simultaneously.

SorbaDex is autoclavable at 121 °C, pH 7 for 30 minutes, and is stable in all commonly used buffers.
