CelloPure⁺ DEAE media consist of highly cross-linked cellulose beads with an average diameter of 100 μm, which are surface modified with dextran to enhance their performance. It gives high binding capacities even in high flowrates. It allows flow rates of 400 to 500 cm/h through a 15 cm column at 1 bar (14.5 psi, 0.1 MPa), enabling quick separation steps—especially useful in the early stages of purification when fast processing is important. During washing and equilibration, the flow rate can be increased up to 750 cm/h for even faster operation. The basic characteristics of CelloPure⁺ DEAE weak anion exchange chromatography media are shown in Table 1.
