Hi all,

I have this little buddy (see images) from millipore, and it's been working
pretty well. I haven't had it for too long, but so far, I'm happy.

Best,
Mariana

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.
