[Histonet] distilled water

Fri May 20 10:15:23 CDT 2005

When I took physical chemistry, we considered 1 Mohm water pure enough for
making solutions for conductometric titrations.  1 Mohm water is certainly
pure enough for histochemistry.  I suspect that the water I now use for
histochemistry has a resistance somewhat less than 1 Mohm.

I am looking to get a distilled water sytem in my lab, but the question
arose
if I need 1Mohm or if 18Mohm is required.  I perform routine routine
histology
experiments, including IHC and immunofluorescence on skin.  Does anyone know
if
the 1 Mohm system would suffice or if I will need to get the 18Mohm system. 
Any help would be greatly appreciated.  Thank you.
