HPLC Columns


TSKgel DEAE-5PW columns are packed with porous hydrophilic polymer beads which are surface modified with a weak anion exchange group. These columns are used for the separation and analysis of proteins, along with nucleotides, nucleosides, and other biomolecules.

TSKgel DEAE-5PW columns are available in internal diameters varying from 2 mm to 21.5 mm and in column housings of either glass or stainless steel.
