SP Sepharose 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 ensure maintained speed even with viscous samples.

Description:SP Sepharose 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 Sepharose 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 Sepharose Fast Flow ion exchangers. The unique flow characteristics are also invaluable when adsorption needs to be done quickly.Feature:- Easy to scale-up- High flow rates- High chemical resistance for effective cleaning-in-place (CIP)- Easy maintenance
