Why a Round Bottom for Heating Applications
A round-bottom shape has no flat base, which allows heat from a mantle or bath to spread more evenly around the flask than a flat-bottom design would, reducing localized stress on the glass during heating or reflux. The narrow neck with a finished rim on this flask suits fitting a single stopper, condenser or thermometer for reflux and distillation set-ups.
