[Nhcoll-l] [EXTERN] Re: Water distilling

[Dirk Neumann]

Hi Joosep,

I would look for certified (industry standard) devices; there are several reliable companies and vendors (search "deionizer lab water purification"), e.g. sartorius, merckmillipore. Might be worth asking a lab planner in Estonia to get an overview over the Estonian market (maintenance).

With best wishes
Dirk

Thanks Simon and John!

Can you suggest some product also that can be in sale in Europe also?

Sincerely,

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

For use with fluid preserved specimens a deionizer would be much better than a distiller. Distilled water tends to be rather acidic, and a distiller requires electricity and heat to operate. 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.

Hi!

I am looking for good product to distill water in lab for fluid-collection.
I think 3-5 L per day is ok.
 Can you suggest something that is also on sale in Europe?
 Also, what it needs to be installed into lab?
