Clear Glass Bottle, Black Tamper Evident Safety Dropper, 30 ml

The glass pharmaceutical bottle with safety dropper is used for filling and dispensing liquid cosmetics drop by drop. Clear glass shows the colour and clarity of the contents, so you can see at once how much is left and whether any cloudiness or sediment has appeared. The black dropper closure has a safety lock that makes accidental opening more difficult, which you will appreciate with concentrated raw materials and fragrances.

The set consists of a bottle with a threaded neck and a dropper with a glass tube, a silicone bulb and a plastic closure. Both parts are declared suitable for contact with cosmetic products, and the set as a whole is intended for cosmetics. The 30 ml volume corresponds to a common pack size for a serum or facial oil.

What the set is suitable for

• Facial serums and concentrates of active ingredients – the dropper takes up only a few drops, and the rest of the contents stays in the bottle without unnecessary contact with air and fingers.
• Facial, hair and nail oils – the oil is dispensed precisely onto the palm or directly onto the skin.
• Essential oil blends and fragrance compositions – the glass tube withstands even strongly aromatic substances, and the safety lock on the closure prevents the bottle from being opened accidentally.
• Tinctures and alcohol extracts – glass resists alcohol, and the colour of the extract is visible through the clear wall.
• Samples of your own formulations – the smaller volume is used up quickly during testing, and after cleaning the bottle can be used again.

Dispensing with the dropper

After unscrewing, the dropper is lifted out of the bottle together with the liquid it has drawn up. Squeezing the silicone bulb pushes the liquid out one drop at a time, and releasing the bulb draws up a new portion. With thicker oils a drop forms more slowly, with alcohol-based and water-based contents more quickly, so try out the dispensing of your particular formulation first.

Volume and filling

Nominal volume is the amount the packaging is designed for under normal filling. Brimful volume is the physical volume of the bottle up to the neck. The difference between them is a reserve into which the glass tube of the dropper dips after screwing on, and in which the contents can expand when the temperature changes.

Good to know

Before first filling, wash the bottle and the dropper, disinfect them with isopropyl alcohol or ethanol and leave them to dry completely. It is enough to rinse the silicone bulb, as long-term soaking in alcohol is not good for it. With pure essential oils and solvents, we recommend checking how the bulb behaves with the particular raw material. The glass tube and the bottle have no problem with them.

Clear glass lets light through. The set is therefore suitable mainly for contents that are not affected by light, or for products stored in a box or a dark cupboard.

Do not pour hot contents into the glass; let them cool down first. A sudden change of temperature can damage the glass, and after cooling the contents drop in level, so the bottle would look underfilled. After thorough cleaning, both the pharmaceutical bottle and the dropper can be used repeatedly. When changing the contents, we recommend replacing at least the dropper, because silicone can retain the scent of the previous contents.

Closures with the same neck type and other ready-made combinations can be found in the Handymade range. With your own combination, check the seal, the dispensing and the behaviour of the packaging with your particular formulation. For recycling, the bottle goes into glass waste. The dropper consists of plastic, glass and silicone, so take it apart before disposal.
