Description
SP Cross-linked Agarose Big Beads are strong ion exchangers designed for industrial applications. The large particle sizes (100-300 µm) and excellent physical stability of the base matrix ensures maintained speed, even with viscous samples. SP Cross-linked Agarose Big Beads are therefore the ultimate ion exchange media for initial purifications when high viscosity precludes the use of ion exchangers with smaller bead size, such as Cross-linked Agarose Fast Flow ion exchangers. The unique flow characteristics are also invaluable when adsorption needs to be done quickly.
Features
Easy to scale-up
High flow rates
High chemical resistance for effective cleaning-in-place (CIP)
Easy maintenance
