Re: incart refilling

[Ken Mantei <kmantei@mail.csusb.edu>]

  Liquids only boil or evaporate until the partial pressure of the liquid vapor
rises to the vapor pressure of the liquid at the prevailing temperature. At
room temperature, in a small, enclosed space such as your storage bag, very
little evaporation will be necessary to saturate the vapors. If you want to
experiment, "vacuum" seal a drop of water in a bag and see how much of it
disappears (to vapor). Then try it with a drop of isopropyl alcohol. I have
experimented, but a quick and dirty calculation predicts that a drop of water
would need about a liter to fully evaporate into, and isopropyl alcohol about
one-third of that. Since the space in your "vacuum" sealed bags is probably
much less, I think much less than a drop of each ink solvent will evaporate.
