Amber Glass Bottle, Black Aluminium Cap, 30 ml

The glass medicine bottle with a black aluminium cap, 30 ml, is intended for contents that are harmed by light: facial oils, serums with sensitive active ingredients, tinctures, essential oil blends and small test batches. Amber glass dampens the light reaching the contents, and the black aluminium cap complements it so that the contents are not exposed to light from above either. The narrow neck makes it easier to pour smaller amounts at a time and reduces the area through which the contents come into contact with air.

The set is declared suitable for contact with cosmetic products. The cap has an inner liner made of foam polyethylene, which seats on the neck when tightened and seals the joint.

What it is good for

• Protection from light – amber glass reduces light penetration, so oils, serums and tinctures keep their scent and colour longer than in clear packaging.
• Glass with no effect on the contents – it does not react with oils, alcohol or essential oils, does not absorb scents, and can be washed and disinfected thoroughly.
• Liner in the cap – the foam polyethylene liner fills the irregularities between the cap and the neck and keeps the seal tight once the cap is hand-tightened.
• 30 ml size – a smaller pack is used up sooner, which helps with oils and serums that oxidise over time. It is also enough for samples or travel packs.

Volume and filling

Nominal volume is the volume the medicine bottle is designed for under normal filling. Total brimful volume, given in the parameters, is the physical volume up to the top of the neck. The difference between them is a reserve for the cap or other closure and for expansion of the contents when the temperature changes. The bottle should therefore be filled to the nominal volume, not to the brim.

Good to know

Before the first filling, wash the medicine bottle and the cap, rinse them with clean water, disinfect them with isopropyl alcohol or ethanol and leave them to dry completely. The same procedure applies when reusing the bottle. Glass withstands repeated washing without limit. Before each new filling, check that the liner in the cap is not damaged or soaked with the previous contents.

Glass does not tolerate sudden temperature changes. Pour warm contents into a medicine bottle at room temperature, not into a cold one.

Other closures with the same neck type, which is given in the parameters, also fit the medicine bottle. You will find them, together with ready-made combinations, in the Handymade range. For your own combination, we recommend checking the seal, the dispensing and the behaviour of the packaging with your specific formulation.

After use, the glass goes into glass recycling and the aluminium cap into metal recycling. Separate them before disposal.
