Finding ultra-pure water locally...


I've been reading up on record cleaning, and there seems to be something of a consensus that rinsing with ultra pure water / lab-grade water / triple distilled water (I'm assuming these are just different names for essentially the same thing?) helps. Where does one buy such water locally? I would imagine paying postage to ship 10 lbs of water would be rather high. I'm in the San Francisco Bay Area. Tks!

Jtimothya: From the description you posted above, I think you'll be very happy with the water you ordered and that it will every bit as good, if not better than the "ultrapure" being shipped by the various manufacturers of record cleaning products.

In looking at the description compared to a "Contaminant Removal Profile" on ultrapure as described by Pall Life Sciences, the company who provides the water purification equipment used in my wife's lab, the only stage that seems to be missing from Pall's ultrapure profile is a combination Ultrafiltration (UF) and UV photo-oxidation stage just prior to a second stage of deionization and the final .2 micron filtration. This is just a guess, but I would guess that the Nerl "Safe and Secure" ultrapure might be subject to this stage to qualify for its "ultrapure" status.

Good luck and keep us posted. I'm pretty sure you and Albert are going to be quite pleased with the results.
So, let's see....

By my calculations, that makes the Nerl Reagent Grade $5.06 gallon when purchased in bulk (so you'd have to possibly factor in buying a few smaller containers) vs. Lloyd Walker's water at $88 gallon.

Hmmmmmm......
Crem1, I went to pep boys and the battery water was $2.99 a gallon, not $4. Am I getting the right water? I should email you directly as I got the prefection steamer and am getting some spitting. Obviously, I'm very impressed by the results.
Let see to really do this right we would need to have a broad range of purity as well as price. We would need to do a broad sampling of records to be cleaned and then rinsed with our rinse water. From my experience with Walker's water and both distilled water bought at the grocery store and RO water from my unit where I heard a cleaner record with the Walker, we might well expect a strong relationship between price and purity, but would we see a strong relationship between purity and cleanliness of records and their sound? Or would waters with relatively high to high purity sound the same down to some point where the sound went bad. The lowest purity before the sound went bad would be the best buy. Do we know if it is a linear and smooth relationship or a step relationship where there is a sudden jump as purity increases? I don't think so.
