Food-grade, Macroporous, Adsorbent Resin

AmberLite FPX66 Polymeric Adsorbent is a macroporous, non-functionalized, adsorbent resin designed for food and biopharmaceutical processing.
In food processing, AmberLite FPX66 can be used for a wide variety of applications to purify and decolorize food-additive streams and to recover high-value materials.
In biopharmaceutical processing, AmberLite FPX66 is an excellent choice for separation and purification of small molecular weight compounds such as antibiotics, vitamins, steroids, amino acids, enzymes, and peptides.
AmberLite FPX66 is resistant to commonly used organic solvents, and it has high mechanical and thermal stability, making it an ideal choice for use in column or batch systems over a large number of process cycles. The resin has high capacity and high selectivity to provide increased product yields.
