Amber Round Sirup Glass Bottle, 28 mm, White Safety Cap, 500 ml

The amber glass medicine bottle with a volume of 500 ml and a white 28/410 safety cap forms a ready-made set for filling liquid products that need to be protected from light and secured against easy opening. Amber glass reduces the amount of light reaching the contents, so it suits contents sensitive to oxidation: vegetable oils, oleogels, alcohol-based tinctures, facial toners and concentrated solutions of active ingredients that are later dispensed into smaller packaging. The set is declared suitable for contact with cosmetics and is approved for direct food contact, so it can also be used for homemade oils, syrups, herbal infusions or vinegar.

Half a litre is a volume for preparation and storage rather than for a finished product for the end customer. It is useful for keeping a larger quantity of macerated oil, hydrosol or toner base, from which smaller retail bottles are later filled. Glass does not react with essential oils or with alcohol, which is not always the case with plastic packaging.

What it is suitable for

• Vegetable oils and macerated oils – amber glass slows down the yellowing and oxidation of light-sensitive oils.
• Alcohol-based tinctures and infusions – alcohol does not damage the glass, and the safety closure makes accidental opening more difficult.
• Hydrosols, toners and aqueous solutions – water-based contents still need to be preserved, as dark glass is not a substitute for a preservative.
• Concentrates and stock solutions – the larger volume suits pre-prepared blends that are gradually added to formulations.

Safety cap

The white cap with a 28/410 neck finish is made of PP and PE and is one of the safety closures that cannot be opened by simply turning. It is useful wherever the contents should not be freely accessible, for example with alcohol-based tinctures or concentrated solutions. Try out the opening mechanism on an empty bottle the first time you use it.

Filling and volume

The nominal volume of 500 ml is the quantity the bottle is designed for in normal filling. The brimful volume given in the parameters is slightly larger and represents the physical volume up to the rim of the neck. The difference serves as a reserve for the cap seal and for the expansion of the contents when the temperature changes. For this reason, fill the bottle to the nominal volume, not to the brim, otherwise the contents overflow through the neck when the bottle is closed and contaminate the seal.

Good to know

Before the first filling, wash the bottle and the cap, disinfect them with isopropyl alcohol or ethanol and leave them to dry completely. Residual water in the neck or in the thread could contaminate anhydrous contents. Glass withstands repeated washing and disinfection, so the set can be used several times, as long as there is no visible damage on the neck or the thread.

Glass does not tolerate sudden temperature changes. Do not pour hot oil or a freshly prepared infusion into a cold bottle; let them cool down first.

The bottle is recycled as glass, while the cap belongs with plastics. Separate the two parts when disposing of them.

Closures with the same neck finish, given in the parameters, and other ready-made combinations can be found in the Handymade range. If you are making your own combination, we recommend checking the tightness and the behaviour of the closure with your specific formulation.
