The Liquid Oval Bottle Adapters are part of the complete set of liquid dosing aids to help your pharmacy run with efficiency. With varying sizes these pharmacy bottle adapters are designed for the Ezy Dose Amber Oval Bottles to ensure a solid seal to prevent unwanted leaks of liquid medications, solvents, and other pharmacy ingredients. These bottle adapters are flexible flanges which provide a tight seal to maintain the USP 671 standard for moisture permeation. Can be used with the child-resistant bottle caps without affecting the seal.
