A flow‐through cartridge for indicating acidic and basic conditions during acid regeneration of immunoadsorption columns is described. Based on a pH dye covalently bound to polyacrylamide beads, it offers a direct visual indication of whether the pH of a column is in a range which is safe for use. The device, mounted in the waste line, may be reused several times.
