What are PuroSorb™ PAD products?

Purolite Life Sciences offers the broadest available range of synthetic polymers with properties that make them highly effective, selective and unique for individual processes, allowing you to fully optimize production yield.

PuroSorbTM polymeric adsorbents (PAD) are synthetic, highly cross-linked polymers with a highly porous structure as part of their matrix. With either non-polar or hydrophobic tendencies, they readily adsorb highly soluble organic compounds. 

They have a strong affinity for hydrophobic molecules such as polyphenols, vanilla (natural flavor) and naringin (citrus flavanone) that have high electronic density (i.e. unsaturated ring such as benzene). The resin attracts the aromatic groups of the molecules.


The full PAD range is highly stable in acidic or alkaline solutions, as well as the majority of commonly-used organic solvents. They can also be regenerated under mild conditions for prolonged life.

PAD products are ideal for a wide range of applications such as:

  • Debittering
  • Decolorization
  • Organic Removal
  • Antibiotic Purification
  • Desalting
As adsorbents interact with molecules in different ways depending on surrounding conditions (such as heat, pH, competing molecules, solvents, etc), our specialists are always on hand to advise the most suitable product for you.
