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

Glass dropper bottle with locking pipette, 30 ml is a complete set for dispensing by drops: an amber glass bottle paired with a matching black dropper with a lock. Amber glass limits light exposure to the contents, which is appreciated for facial serums, oil blends with essential oils, tinctures, or concentrated active ingredients that lose effectiveness more quickly in light. The dropper allows precise application of small doses without finger contact with the contents, making it suitable wherever hygiene and measured amounts matter.

The set is supplied as a ready-matched pair of container and closure, fitting each other in both seal and length. The dropper reaches deep enough to draw contents even when the fill level is low.

What the set is suitable for

• Facial serums and oil elixirs – drop-by-drop dispensing matches the typical amount for a single application and the contents are not exposed to air more than necessary.
• Essential oil blends and aromatherapy concentrates – dark glass and the glass tube of the dropper tolerate strongly aromatic ingredients better than standard plastics.
• Tinctures and alcohol extracts – glass does not react with alcohol and the dropper makes dispensing drop by drop easier.
• Samples and test batches – the 30 ml volume is sufficient for verifying a formulation and the dropper allows drawing content without contaminating the remainder.

The set as a whole is declared suitable for contact with cosmetics. The glass bottle has a separate certificate for direct food contact; the dropper does not, so the set is intended for cosmetics, not for food use.

How the set works

The dropper consists of a glass tube, plastic closure and silicone bulb. Squeezing the bulb draws the contents into the tube and releases them drop by drop. With thicker oils or higher-viscosity serums, the uptake is slower and the drops larger, which should be taken into account when stating the recommended dosage on the label.

The lock on the closure prevents accidental opening, for example during transport in a bag or when handling at home. Before first use, practise closing and opening it dry so you can explain the unlocking mechanism to customers or household members.

Nominal and total volume

Nominal volume is the amount for which the bottle is designed at standard fill. Total brim volume is the physical volume up to the neck, which is slightly larger; exact values are listed in the parameters. The difference is a deliberate margin for the submerged dropper tube and for expansion of the contents when the temperature changes. The bottle should therefore be filled to the nominal volume, not to the brim. If overfilled, inserting the dropper will cause contents to overflow through the neck and contaminate the thread, which compromises the seal.

Useful things to know when working with the packaging

Before the first fill, wash both the bottle and the dropper, disinfect with isopropyl alcohol or ethanol and allow to dry completely. Residual water in the dropper tube would dilute the first dose and could cause cloudiness in anhydrous oil-based products.

The glass bottle can withstand repeated use. When refilling, clean it the same way as for first use and inspect the thread and neck for chips. The silicone bulb of the dropper loses elasticity over time, particularly with exposure to essential oils. If the dropper stops drawing reliably, replace it.

Glass does not tolerate sudden temperature changes. Allow hot phases to cool to at least lukewarm temperature before filling, otherwise cracking may occur.

Apply the label to the cylindrical part of the bottle. When disposing, separate the dropper from the bottle and put the glass bottle in glass recycling.
