If it isn't, I think I'd shop elsewhere, as for instance a chemical supply store (probably cheaper there anyway).
Acetone is not an expensive chemical, as such things go. I shold prefer strongly to buy a bit more quantity than to pay a substantially higher price for a small, 1-fill-up quantity.
Also -- very important -- OBEY the storage instructions! Acetone is highly volatile under certain circumstances. You don't want any part of that game, m'friend, not at ALL!
FReegards!
Mucho thanks for the info & advice!
