Precision Eye & Ear Drop Glass Vials

Eye and ear drops are dispensed one drop at a time into a sensitive area, so the container is really a precision dropping system. The dropper or controlled-drop tip is engineered to release a consistent drop size and to limit contamination, while the glass vial provides an inert, stable container for delicate ophthalmic and otic formulations.

Glass is particularly valued for sensitive actives and preservative-free products, where it avoids the absorption and leaching that can occur with some plastics over shelf life.

These vials carry ophthalmic eye drops, otic ear drops, lubricating and dry-eye drops, antibiotic and steroid drops, glaucoma medications and preservative-free formulations, as well as veterinary eye and ear products. Ophthalmic manufacturers, compounding pharmacies and specialty brands use the format. The 2–10 ml sizes match typical treatment courses and multi-dose eye drops; 15–30 ml suits ear drops and veterinary presentations.

The vial is small and straight-sided, with a stable base and a dropper finish dimensioned for eye and ear dropper assemblies. Amber protects light-sensitive actives; flint lets patients see how much product remains. Closure options include glass pipettes with rubber bulbs, LDPE dropper inserts and controlled-drop tips, finished with a child-resistant or tamper-evident cap. The tip geometry sets the drop size, so we select it with your formulation’s viscosity in mind.

Ophthalmic products are sterile, so the drug manufacturer qualifies the vial, dropper and cap together as a sterile system and characterizes drop size for the formulation. Component compatibility with the active and any preservative is part of that work. Patients are instructed not to touch the tip to the eye or ear. Send us your formulation, fill volume and target drop size and we’ll match a vial, tip and cap and supply samples for testing.

We produce the vials by tubing conversion or molding, with a precisely formed dropper finish, then anneal and inspect them; amber color comes from the batch chemistry. Certificates of analysis and compliance documentation are available on request, and we can supply vials washed and packed ready for your sterilization process. Droppers, tips and caps are sourced to match the finish, with custom cap colors and screen printing available.
