[Histonet] distilled water

[Kristopher Kalleberg]

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.
