One Socket Size Across the Whole Capacity Range
Unlike some jointed flasks that pair different socket sizes with different capacities, this Flat Bottom Flask with Joint uses a single 24/40 socket size across its entire 50ml to 2000ml range — simplifying stopper and fitting selection when a lab stocks multiple flask sizes for different batch volumes. The flat base gives it a stable benchtop footing that a round-bottom flask does not have.
