Analysts processing protein or other biological preparations, sterile pharmaceuticals, foods, or beverages must separate wanted products from unwanted process components.

Porozorb cartridges are produced using validated processes, providing sterile, endotoxin-free, ready-to-use adsorbent cartridges that effectively remove detergents (Triton X-100, sodium dodecyl sulfate, TWEEN®, etc.) or other nonpolar, hydrophobic materials from such preparations. They are appropriate for analytical scale to process scale purification schemes.

A certificate of analysis accompanies each Porozorb cartridge. Cartridges are tested for sterility and endotoxin by an accredited test lab following modified USP guidelines. The cartridges can be rinsed with cleaning agents (e.g., most weak acids and bases) or autoclaved at 121 °C. The polycarbonate cartridge can accept 50% organic solutions during analysis, but must be stored in aqueous solutions.

Other Notes

Porozorb cartridges are not for clinical or diagnostic use.
Due to shelf life limitations, Porozorb cartridges are made on receipt of an order. Expect 2-4 week delay in shipping times.
