Stoppering and Supporting the 250 ml Flask
Because the neck is tooled to an even bore, a stopper of the matching size seats squarely, which matters when it carries a thermometer or a delivery tube. Clamp the flask by the neck over a wire gauze for heating, and rest it in a flask ring or cork ring at other times, since the round base rolls on a flat bench. Never heat it with a solid stopper closing the neck; vapour needs a way out. The flask can be autoclaved, and the 250 ml size heats a small charge of liquid quickly.
