With regard to storage, I ran across the following from a Wikipedia article on Dionized Water:
"Laboratory grade ultra pure water cannot be stored in glass or plastic containers because such materials leach contaminants at very low concentrations into the water. Storage vessels made of silica are used for less demanding applications but for highest purity uses, containers made from ultra pure Tin are used."
With regards to buying, to follow up on Hdm's earlier posts, the numbers 9800-1, -3, -5, appear to be product numbers for different packagings of Reagent Grade Water from NERL Diagnostics, a division of Thermo Scientific. Likewise the "Safe & Sure Ultra Pure Reagent Grade Water" appears to be a higher grade and has a different product number. It doesn't seem to be sold on-line by the various supply houses, however one can get a quote for it from Thermo Scientific
If that is the case, MedicalMailOrder.com is offering the 20 liter (~5 gallon) 9800-5 Reagent Grade water at $25.32 plus shipping ($8.27 UPS ground to my zip in upper Midwest where it is a balmy 3 degrees F.)
I'll find out how much fun is a five gallon box of frozen water. (Not just any water, Mr. Bond, reagent grade laser water.)
