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.
