Amber Glass Bottle, Silver Aluminium Cap, 30 ml

A glass bottle, amber vial with an aluminium cap, 30 ml is a ready-to-use set for filling smaller cosmetic volumes. Amber glass reduces light transmission, making it suitable for contents sensitive to light – facial serums, oil concentrates, essential oil blends or samples of your own products. The aluminium screw cap matching the bottle neck seals the contents tightly and is ideal wherever the contents are poured or measured directly, without a dropper or pump.

The set is declared as suitable for contact with cosmetics. The glass bottle alone also holds a certificate for direct food contact, but the complete set is intended for cosmetic products.

Why choose amber glass with an aluminium cap

• Light protection – amber glass absorbs a large portion of light that accelerates oil oxidation and the loss of essential oil fragrance. The contents thus retain their original properties longer than in a clear container.
• Glass does not react with the contents – it does not absorb fragrances, does not discolour and resists oils, essential oils and alcohol-based solutions. It is therefore also suitable for concentrated blends that would eventually cause plastic to soften or take on the scent.
• Tight metal closure – the aluminium cap has a sealing insert made of foam polyethylene that sits on the neck and prevents leakage and the escape of volatile components. It unscrews and tightens back easily.
• Small, practical volume – 30 ml is enough for a serum, a travel-size oil, an essential oil blend lasting several weeks, or a sample for a customer.
• Reusable – the glass bottle can be washed, disinfected and refilled, which you will appreciate when testing formulations and in small-batch production.

Suitable for products such as

The set works best with contents that do not require a dispenser and are poured directly from the bottle or measured drop by drop from the neck. These are typically facial and hair oils, oil serums, essential oil blends for diffusers and aromatherapy, tinctures and alcohol-based solutions, as well as small sample volumes of hydrolats or tonics. For water-based and emulsion contents, do not forget preservation – the packaging does not replace it.

For manufacturers, the 30 ml set is also a practical sample container: a small quantity in packaging that closes securely and can be cleaned and reused after being returned.

Nominal and total volume

The nominal volume is the volume the bottle is intended for during regular filling – in this case 30 ml. The total brim volume is the physical volume up to the neck and is somewhat larger. The difference between them is the headspace for the cap, a possible dropper, and for the expansion of the contents when temperature changes.

Filling, cleaning and reuse

Glass tolerates normal filling temperatures but is sensitive to sudden temperature changes. Allow the hot oil phase or freshly melted balm to cool first and fill only when the contents are lukewarm. The narrow neck of the vial is best filled using a funnel or a syringe to prevent contents from remaining in the thread.

Labels adhere well to the cylindrical body of the bottle. When reusing, remove the old label and any adhesive residue before washing to prevent them from getting inside.

Caps with the same neck type as specified in the parameters, and ready-made bottle and dropper or sprayer combinations are available from Handymade. With your own combination, we recommend verifying the seal, dosage and container behaviour with your specific formulation, particularly with concentrated essential oils and solvents that may affect the sealing insert over time.
