I presume you are concerned about H2O evaporation. What does Not work is enclosing a smaller volume around your experiment. The easy key is to find an immiscible liquid to float on top ( less dense ) of your H2O and block evaporation. After that finding more solutions ( keys ) starts to get NASA complicated.
It dep3nds on how you define none evaporates - eg if you just need to keep it in a container then seal the top - if you mean none to leave the body of liquid then much harder.
