Exactly fills the bill for those whose needs are too small for a full size deionizer, and too large for small laboratory a p paratus. It alone offers: — High output; low cost—Delivers u p to 120 G P H of deionized water, chemically p u r e r t h a n distilled water. Does it a t a fraction of distillation cost. Complete; ready to go—Hook it right into water supply line; delivers deionized water a t line pressure where a n d when you want it. Built-in controls regulate pressure; signal when effluent drops to ohmage (purity) of distilled water. No regeneration—We do it for you! Ion exchange material is in easily handled bags; extra bags supplied with t h e unit. W h e n material is spent, simply replace with fresh bags which come right with t h e unit. T h e n r e t u r n spent bags t o us for p r o m p t regeneration. You always have a supply on hand. N o back-washing, no acids or alkalis to handle, no trained operator needed. No expensive throw a w a y cartridges. Nothing to get out of order. Write for facts
