In Reply to: lab grade water needed posted by chosenhandle on September 12, 2006 at 06:34:07:
the question is - do you really need it? regular distilled water works for me, and I've been through all the major cleaning systems.

Having sold scientific products and supplies I can tell you that often material is shipped freeze dried and must be reconsistuted for lab testing.The water they use for reagents, test kits and sampling is lab grade water. Typically this is triple distilled and deionized water. This gives the equipment greater reproductable lab results and lab QA usually require 97 percent reproducability to maintain their licenses.
Lab water is perfect for reproduceable testing results and is probably way overkill for record cleaning. I feel my standard distilled water I buy at the grocery store is perfect for a final rinse on my thrift store finds.
