Reading the Neck Size Against Capacity
The neck size (N/S) column is the standard ground-joint reference for each flask, and it is what determines which stopper and interchangeable-joint accessories will fit — note that the 50ml and 100ml capacities are each available in two neck sizes, so buyers standardising on a single stopper size across their glassware should confirm which N/S variant they are ordering. Tolerance widens steadily with capacity, from ±0.04ml at the 5-25ml sizes up to ±0.6ml at 2000ml, consistent with the way volumetric accuracy is specified across the Class-A range generally.
