The chemistry flask is a legendary junk item in Fallout Shelter and thus can only be found at high level quests, on long dweller explorations or locations, with a low percentage chance of obtaining it. It can also be rarely found in a lunchbox. Like most items, it takes up one space of storage.
Currently it is used for creating various weapons and armors in combination with recipes found in the wasteland and other junk of various quality. It is however, generally used to make higher quality items with workshops of various levels.
