[Nhcoll-l] Water distilling

[Simon Moore]

I would endorse what John has just said as I have tested the pH of distilled waters and have found them to go down to pH 4!

With all good wishes, Simon

A deionizer is simply a resin exchange column that can be hooked up to existing plumbing. You do not need ultra-clean water for mixing preserving fluids, so the system does not have to have multiple filters or resin columns.
