AmberLite FPA90 Cl

Summary

Product identification

Product Name: AmberLite™ FPA90 Cl Ion Exchange Resin Product Type: Food- and Biopharmaceutical-grade, Styrenic, Macroporous, Strong Base Anion Exchange Resin

Description

AmberLite™ FPA90 Cl is a styrenic, macroporous, Type I strong base anion resin specifically designed for the decolorization of liquid sugar syrups. It is also suitable for biopharmaceutical processing, including natural product extraction and recovery of antibiotics from fermentation broth, such as in aminoglycoside and macrolide antibiotic processes.
