  deionizer \de*i"on*iz`er\ n. (Chem.)
     an apparatus used to remove ions from a solution; a common
     variant contains a mixture of cation exchange resin in the
     acid form and anion exchange resin in the hydroxyl form
     inside a replaceable cartridge; ions in aqueous solution are
     exchanged for the elements of water by passing the solution


     through the mixed resin.
  
     Note: In chemistry and biochemistry, experiments often
           require water free from contaminating ions, and
           ordinary distilled water may be further purified by
           passing through a deionizer in order to render the ion
           content sufficiently low so as not to interfere with
           the investigation.
