E-Pak®

E-Pak cartridges are radial flow adsorption cartridges developed specifically for pharmaceutical processing. Created with proprietary technology, E-Pak cartridges provide the rapid kinetics of fine particle adsorption at flow rates and capacities suitable for laboratory, pilot plant, and full-scale commercial operations. They are designed for use in both aqueous and organic solvent systems, and incorporate design features compatible with use in explosion proof environments.

  • Proven cartridge design assures simple, reliable adsorption processes with excellent scalability from bench scale to full commercial production
  • Fixed porous media completely eliminates handling and safety issues associated with loose carbon
  • Large adsorption capacity in a small footprint increases product recovery and reduces solvent requirement
  • RETROFIT KITS available to allow cartridge use in most existing filter housings

Applications: E-Pak adsorbent cartridges are designed for the purification of API’s and intermediates dissolved in polar and nonpolar solvents. Primary applications include removal and recovery of catalyst, reaction-by-products and color from synthetic reaction mixtures and natural products. Compared to loose media, prepacked columns and ventricular style filters, Graver Process Scale Adsorbents provide important advantages including: Reduced process time, increased purity and recovery, improved safety, handling disposal, and lower operating cost.

E-Pak adsorbent cartridges are available in a range of sizes and formulations (based on many of the adsorbent formulations in our Ecosorb C-Series of adsorbents) to accommodate the broad range of processing requirements encountered over the typical API development cycle.

Graver supplies filter housings for the complete range of cartridge sizes and configurations available, and will also supply retrofit kits for many commonly used filter housings. Contact Graver for complete details.
