The SelRO nanofiltration membranes provide outstanding chemical and thermal stability to satisfy the demanding requirements of pharmaceutical processes involving high and low pH, high temperature and organic solvents media. Most nanofiltration membranes previously available were limited to aqueous applications within the pH range from 2 to 11. The SelRO membranes can be operated within a pH range of 0–14. They enable the concentration of pharmaceutical intermediates in aqueous solutions, which may also contain organic solvents such as methanol, ethanol, acetone, acetonitrile and others. The membrane modules are available in tubular and spiral configurations in a wide variety of pilot and commercial sizes.
