It puts a lower limit on conductivity, but does not define whether it is 
a resistor or not.
Resistors and insulators are separated by a matter of degree with the 
area in between defined as semiconductors, not absolutes.

and most likely not even necessary with DI and distilled water in such 
small systems if the reservoir  is large enough.
