RE: [Histonet] water purification

From:"Monson, Frederick "

Morning Evelyn,
	There should be NO conductivity and resistance, therefore,
should be EXTREMELY high.  For all molecular biology procedures that I
can remember using, I redistilled deionized water in a scrupulously
clean all glass still.  Once I had a system, I used such water for all
my histo- or cyto- preparations and methods, and reserved tap water for
post-rinsing Schiff's reagent and final stabilization of H in H&E.

	With respect to deionizers, the ion trapping bed is generally
specially chosen for the water that is to be processed, and thus, often
does a more-than-adequate job.

Good afternoon,

I wonder if someone could tell me;
What sort of conductivity should one obtain in water purification
systems (deinoised water)for use in PCR? I would be much obliged if you
could help out.
