Flasks reaction

Laboratory flasks are vessels or containers which fall into the category of laboratory equipment known as glassware. In laboratory and other scientific settings, they are usually referred to simply as flasks. Flasks come in a number of shapes and a wide range of sizes, but a common distinguishing aspect in their shapes is a wider vessel “body” and one (or sometimes more) narrower tubular sections at the top called necks which have an opening at the top.
