   Following up on Wannabe....    
      
   I am indirectly responsible for the care-and-feeding of a lab-grade RO/DI   
   water system serving a 600,000 research facility and vivarium.  It occupies   
   over 300 square feet of footprint, runs 24/7 and will produce hundreds of   
   gallons per hour, if needed.    
   Points:   
      
   Lab Grade RO/DI water is very nearly mineral and salt-free, free of dissolved   
   gasses, metals and other trace elements or contaminants, and very nearly   
   unreactive. Meaning that it is nearly impossible to hydrolyze (break down into   
   H2 & O2 by running a    
   current through it). There are five separate steps in making the stuff, from   
   City Water to Product, including pre-and-post filtration, softening, and going   
   through the De-Ionization and Osmosis processes. This is NOT distilled water,   
   and it is created by    
   a far more complex process than simply boiling water.
