Looking for fresh DI resin or a deionization kit? When you need zero total dissolved solids (TDS), Air, Water & Ice can help! Our team offers premium color-changing mixed bed deionization / DI resin (strong base CATION + strong base ANION). Our Guaranteed Fresh Factory Direct Deionization Resin is a 1:1 volumetric mixture of CG8-H (an amber-colored hydrogen form cation resin) and SBG1P-OH-ID (a dyed hydroxide form type 1 porous strong base anion resin). The anion component is infused with a permanent pH indicator dye that changes color from blue to amber as the resin exhausts. MBD-30 is intended for use in cartridge applications where a color indication of resin exhaustion is desired.
