Flasks that are larger than 2000 mL may contain a 45/50 Rodaviss stopper joint in the center neck, for various attachments or for allowing larger magnetic stir bars to be placed inside the flask.
Having a stir bar that is too big may prevent stirring from occurring in a round bottom flask, as the stir bar may be too large to seat correctly.
