Essential Oil Droppers & Pipettes

Closure choice depends on how the product should be dispensed. Common options include droppers and pipettes, reducer inserts, roller-ball systems and screw caps.

Select the closure around the bottle neck, formula viscosity, target dosage and consumer use. Confirm the complete bottle-and-closure assembly for fit, sealing and dispensing before production.

Formula compatibility can be evaluated, but it must be confirmed with the actual product and all liquid-contact materials. Glass may be only one part of the system; pumps, gaskets, bulbs, reducers, rollers, plugs, liners, coatings and adhesives can also interact with the formula. Provide the intended formulation and selected components so an appropriate test plan can be agreed. Final approval should be based on representative filled samples under the required storage and use conditions.

Provide the exact container model whenever possible. If a model is not available, measure the finished opening or neck and include the dimensions that control component fit: outside and inside diameter, thread or crimp specification, rim or lid-seat geometry, relevant heights and any insertion depth.

For pumps, also provide the neck finish and required dip-tube length. For lids and stoppers, a technical drawing or physical sample is strongly preferred because nominal diameter alone does not describe threads, tapers, gaskets, inserts or fit tolerances.

Separate accessory orders may be possible, but compatibility must be confirmed before production. Provide the Bright Glassware model number or the exact bottle or jar opening/neck dimensions, required material and finish, quantity and, when possible, a drawing or physical sample.

Do not assume an accessory will fit only because the nominal diameter looks similar. Opening geometry, thread or insertion details, tolerances and component construction should be checked on representative samples.
