Type II grade of reagent water is prepared by distillation using a still designed to produce a distillate having a conductivity of less than 1.0 µS/cm at 298 K (25°C).


  • Deionized
  • Used for general laboratory applications
  • Suitable for feeding ultra-pure systems, among other uses


Ion exchange, distillation, or reverse osmosis and organic adsorption may be required prior to distillation if the purity cannot be attained by single distillation.
