About the 2 mL reference
The 2 mL amount is the RetaGrade reference used in this guide.
It applies to the catalog-vial example shown here and should not be presented as a clinical-trial rule.
Confirm vial capacity: The vial must hold the full 2 mL with usable space remaining. Never force liquid into a vial that is too small.
