The Established IEX Chromatography Media


For Reliable and Effective Protein Purification

Fractogel® media provides the reliability that your applications demand – optimal yields, efficient purification, and an extremely long product lifetime. The innovative tentacle technology of Fractogel® resins offers a number of advantages compared to conventional materials.

The Matrix

Fractogel® media consist of synthetic methacrylate based polymeric beads, providing excellent pressure stability resulting in high flow rates. Depending on your application, you can choose from medium sized M-type beads with a particle size of 40-90 μm, and small S-type beads with a particle size in the range of 20-40 μm.

The Tentacles
The tentacles

Tentacles are long, linear polymer chains that carry the functional ligands. All tentacles are covalently attached to hydroxyl groups of the Fractogel® matrix. This configuration provides a high surface area for biomolecules to bind without steric hindrance. The results: efficient separation and a high binding capacity even at high flow rates. A variety of ligands is available for different chromatography applications, including ion exchange, affinity, hydrophobic interaction, and size exclusion.

High Stability for Multiple of Chromatography Cycles

The excellent pressure stability of Fractogel® media enables very high throughput rates which in turn lead to excellent yields. The high binding capacity of Fractogel® media even at high flow rates saves valuable time and improves process economics. Due to the stronger binding, Fractogel® media provide more reliable results and can be flexibly used in many different applications. Its high stability enables efficient Cleaning in Place (CIP) using a sodium hydroxide solution, extending the lifetime of Fractogel® media even further, up to hundreds of purification and recovery cycles. Longer product lifetime minimizes replacement frequency and enables lower operating costs.
