Answer:
The Acrodisc® unit with positively-charged, hydrophilic Mustang® E membrane is ideal for the removal of endotoxin from solution due to its highly crosslinked quaternized amine charged surface. This gives very high dynamic capacities under selected conditions for the removal of endotoxin from process feedstreams, buffers, and water.
