How to Choose the Right Serum Bottle for Your Formula

Compare serum bottle droppers, treatment pumps, capacities and glass options, and learn what to test with your formula before bulk production.
Serum Bottle Pipette Length describes the relationship between a dropper pipette and the internal height of the bottle it serves. The length must allow the tip to reach the formula at expected fill levels while avoiding contact with the base that could block uptake, crack glass, or leave an unusable residue. It also interacts with neck finish, collar, bulb, and bottle shoulder geometry, so a pipette should be selected as part of the complete dropper assembly. Buyers should check filled samples at minimum and maximum fill volumes, confirm dosing behavior, and assess whether the pipette remains straight and stable during use. Physical measurement and functional testing are more reliable than nominal bottle capacity alone.
