select the right vial stopper
typical vials
10–13 mm (2 mL), 16–20 mm (10–20 mL), 28–32 mm (100 mL+)
outer diameter of the vial neck
not the cap, not the volume
Bottle capacity (2 mL, 10 mL, 100 mL, etc.) has no bearing on stopper selection - two vials of very different volumes may share the same neck diameter and therefore use the same stopper
When in doubt, contact us with your measurement and we will confirm the correct specification.
