PuroSorb™ adsorbents are chemically stable, insoluble, spherical and highly cross-linked polymer. These adsorbents are stable in acidic or alkaline solutions and in most organic solvents. Additionally, they can be regenerated under mild conditions for prolonged life. PuroSorb™ resins are offered in a variety of base matrices, porosities (or pore volumes), surface areas, and pore sizes. They also exhibit non-polar or hydrophobic tendencies which means they readily adsorb highly soluble organic compounds.
