Save money by refilling your own DI resin cartridge!  This semiconductor grade resin is available in three sizes, and with or without a color indicator.  Resin with the color indicator changes from a deep purple (almost black when wet) to a light tan color when exhausted.  The color change is visibly obvious. The 1.25 lb refill is enough resin for a single refill of a 10" x 2.5" cartridge.  Need larger quantities of any DI resin?  No problem - give Buckeye a call!
