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 unit 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.
