WebTOYOPEARL HW-65S resin is chemically stable from pH 2-14, and it is this stability that allows a constant packing volume over a wide range of salt concentrations and cleaning in place (CIP) with acid or base. Also, this resin can be run at elevated temperatures (4 - 60 °C) and is autoclavable at 121 °C. WebTOYOPEARL HW-65F resin has a 100 nm pore size and a 45 µm bead size. Surface hydroxyl groups render this resin very hydrophilic, therefore minimal non-specific adsorption occurs, making the TOYOPEARL HW-65F resin useful for protein separations of biomolecules between 40,000 and 5,000,000 Da in size.
