Hi Steve and all, High Density Poly Ethylene; HDPE is said to put nothing in the water. I wrote Nalgene about their resin's surface charge characteristics and they said they do not know and refereed me to a analytical chem text.
Because it puts nothing in the water does not necessarily mean that it does not take from or affect what is in the water. Glass is soluble in distilled water. I don't remember the details, but probably have some info on that in my files/piles. Nalgene says that their HDPE is "Excellent" for the storage of DW at both 20C and 50C.

I wade through all the off-topic posts looking for your post and others who are doing some hard research on this topic. By the way can you and/or other experts develop some sort of standard for visually determining the size of colloids or strength of solution? I know there are quite a few variables. I stick with clear solution registering a strong TE. Make sense? I'm still wondering about using plastic. Sure, the silver will move around in the DW for years potentially, but won't they lose their effectiveness if they gain electrons? Can plastic gain/loose electrons (be affected by static electricity)? Isn't glass a better insulator preventing capactive or actual transfer of electrons from outside to silver ions?
