DOWEX® Ion Exchange Resins

DOWEX® Ion Exchange Resins

DOWEX® resins are made of spherical particles. The benefit for the user is a highly efficient exchange process, due to optimal flow-through kinetics because of the round (spherical) particles.

We offer a broad range of DOWEX® ion exchangers (anion and cation) featuring small particle sizes and narrow particle size distributions (50 - 100 mesh, 100 - 200 mesh, 200 - 400 mesh). In addition, analytical grade qualities of DOWEX® resins are available. These products are processed from original DOWEX® (»practical grades«) resins, following a proprietory procedure developed by us.
