A Consistent 24/40 Joint Across the Whole Range
Like several other jointed flasks in this range, this Round Bottom Flask uses a single 24/40 socket size across its entire 50ml to 1000ml capacity span, so stoppers, condensers and other 24/40 fittings already in a lab's inventory will fit any size in the range. The round-bottom shape suits even heat distribution for reflux and distillation work.
