Class-A Tolerance With a PE Stopper
This flask pairs Class-A certified tolerance — the tighter of the two standard tolerance classes — with a polyethylene stopper rather than glass, giving a lighter closure that will not chip like a ground-glass stopper. The neck size (N/S) column determines which stopper and accessories fit each capacity, and the 50ml and 100ml sizes are each available in two neck-size variants.
