Bottle Adapters (Orifice Reducers)

Press-in bottle adapters allow for increased dosing accuracy. Available in various sizes, they fit securely in any bottle with a corresponding opening size. The adapters allow a user to easily draw liquid, ensuring accurate dosing while avoiding spills; they fit flush with the bottle opening so that the original cap can be placed on the bottle. Press-in bottle adapters are available in vented and non-vented forms.

Vented adapters can be used where large doses coupled with low head-space may create a vacuum inside the container. The vent allows air into the bottle as a dose is extracted.


  • 20 mm, 24 mm, 28 mm, and 33 mm sizes
  • Easy, spill-free prefilling of oral syringe
  • Innovative design works with glass or plastic
  • Low profile allows use of standard closure to seal bottle
