Just out of curiosity, what is the limit for impurities in the lab grade water? It has been a decade or so since I worked in a lab, but if I recall correctly the specification for Purified Water USP was 1 ppm total dissolved solids. This is the water we routinely used except for sensitive HPLC testing. Lab grade can mean different things.
Also, the downside to purchasing in large quantities is the length of time it would take to use it all after opening the bottle. It is not easy to keep things from growing in your water. Those specifications dont mean a thing after that.
