Deionized Water (Type II) is a very clean, high purity water for many industries including laboratory, pharmaceutical, cosmetic uses and more.
Deionized water has gone through a treatment which removes all ions and impurities in the water, making it less likely to negatively impact the manufacturing process.
What's the difference between deionized water and distilled water?
Distilled water is water which has been turned into steam and collected.
Deionized water passes through a chemical treatment process which ensures that all positive/negative ions and charges have been removed.
Distilled water conducts electricity, whereas deionized water does not.
