Glass bottle, glossy black, black dropper with glossy stripe, 15 ml

Black glass bottle with dropper is a ready-made set for filling small volumes of liquid products where protection of the contents from light and precise drop-by-drop dosing matter. The opaque black glass blocks light completely, making it particularly suitable for facial and oil serums with sensitive active ingredients, essential oil blends, concentrates and samples. The 15 ml volume corresponds to a standard facial serum packaging or a small oil blend.

The set consists of a glass vial with a glossy black surface and a dropper with a matte black collar and a glossy stripe that matches the bottle in colour. The dropper screws onto the neck like a standard cap. Its glass tube reaches almost to the bottom and the silicone bulb allows you to draw up and dispense the required amount without the contents touching your fingers.

Why this set

• Light protection – black glass is opaque, so the contents are not exposed to daylight or artificial light. For oils prone to oxidation and serums with sensitive active ingredients, this is more practical than clear or merely tinted glass.
• Drop-by-drop dosing – the dropper allows you to measure out exactly as much as needed for a single use. For concentrated products, this is more economical and hygienic than pouring from the neck.
• Glass with no interaction with the contents – both the glass bottle and the glass tube of the dropper are chemically inert, do not absorb scent or colour, and tolerate oil-based, water-based and alcohol-based contents.
• Uniform appearance – the matte collar with a glossy stripe on glossy black glass looks cohesive even without a label, which is appreciated for samples or small batches.
• Matched dropper length – the tube is matched to the height of the bottle, so the last residue of the contents can also be drawn up.

Filling and dosing

The bottle has a nominal volume and a total volume to the brim, both values are listed in the specifications. The nominal volume is the quantity the container is designed for during normal filling. The total volume is the physical capacity up to the neck. The difference between them is the headspace you need with a dropper: when screwed on, the tube is submerged in the contents and displaces some liquid upwards, and the space is also needed for expansion of the contents when the temperature changes. The bottle should therefore be filled to the nominal volume, not to the brim.

Before the first filling, we recommend washing the bottle and dropper, rinsing with isopropyl alcohol or ethanol and allowing to dry completely. Any residual water in the tube would otherwise get into the anhydrous oil or serum.

What is good to know

The set is declared as suitable for contact with cosmetic products. The glass bottle has a certificate for direct food contact on its own; the dropper does not. The set as a whole is therefore intended for cosmetics and we do not recommend it for food use.

The dropper consists of a plastic collar, a glass tube and a silicone bulb. Glass is neutral towards the contents, but silicone and plastic may soften or absorb scent over time with prolonged contact with concentrated essential oils, undiluted fragrance components or solvents. With such contents, we recommend monitoring the condition of the bulb and using a new dropper when changing the formula.

The glass bottle can be reused and withstands washing and alcohol disinfection. Avoid sudden temperature changes, such as filling hot contents into cold glass. The glossy black surface holds light or transparent labels with white or gold print well. When recycling, the bottle goes into glass; the dropper, once disassembled, is sorted by material: the tube as glass, the collar as plastic.

Closures with the same neck type as listed in the specifications, and other ready-made bottle + closure combinations, can be found in the Handymade range. For a custom combination, we recommend verifying the seal and dosing with the specific contents.
