ionXelmitge LABORATORY SIZE OF CARTRIDGE DE-IONIZER GIVES MINERAL-FREE WATER The latest development in ionXchange equipment is the mixed-bed de-ionizer, which combines both anion and cation resins in one vessel or tank. The unît shown below is a miniature model of such a de-ionizer, made up in such a manner as to be an ideal accessory in any laboratory where mineralfree water is wanted occasionally in comparatively small quantities. The ILLCO-WAY Cartridge De-Ionizer consists of a plastic tubular column containing 3 lbs. of mixed resin. When the resins are exhausted, as shown by a change in color, the entire cartridge can be discarded and a fresh one substituted. N o electrical connections are needed. The column can be clamped, as shown, in any convenient location or manner. RESEARCH MODEL Produces water comparable to that obtained by triple distillation. Removes all ionizable solids, including silica and CO2.

CAPACITY - 4 5 0 grains
