Serum Bottles Explained: Droppers, Pumps, Sizes & Glass Options
April 3, 2026
Learn how serum bottles differ by glass, capacity, neck finish, dropper or pump system, decoration and formula compatibility.
Serum Bottle Sample Approval is the formal evaluation step before bulk production, where the buyer reviews a physical assembled pack rather than drawings or catalog specifications. It typically covers bottle glass, neck finish, dropper or pump, gasket, dip tube, decoration, labeling, fill volume, and interaction with the actual formula. Approvers should confirm dimensional fit, sealing, torque, dispensing, leakage resistance, appearance, and filling-line behavior under agreed conditions. Because glass and component colors, finishes, and decoration can vary between lots, approval should reference retained samples and clearly documented specifications. Successful sample approval establishes the reference standard for later production, inspection, and dispute resolution.
