> Shielding the fluid of interest from mixing with the surroundings will prevent evaporation (close the bottle of water and it will remain full, leave it open and then it will evaporate eventually).
If you close the other end, pressure will prevent the ink from flowing out the tip.
- bernulli 6y agoMaybe, if it’s not about a bottle of water where we don’t want anything to flow out, one could use some sort of Transparent Material At The End Of A Gel Pen Refill to close the plastic pipe and prevent exposure to air to prevent evaporation!
- zaarn 6y agoThere is gas pressure pens that have a small amount of pressurize inert gas at the end instead, which means that those are in fact closed on the end and operate much longer due to no evaporation issues.
