Amber Boston Round Sirup Glass Bottle, PP28S, Bakelite Black Cap, 1000 ml

Amber glass medicine bottle, Boston, PP28S, black low cap, 1000 ml

This one-litre amber glass medicine bottle with a black low cap serves as a storage bottle for makers who prepare ingredients in larger quantities or dispense from one container into smaller retail packaging. It is supplied as a ready-made set, prepared for filling. The dark glass reduces the passage of light, so it suits contents that deteriorate when exposed to light: vegetable and massage oils, macerated oils, hydrosols, tinctures or liquid bases for shampoos and shower gels.

The set as a whole is approved for direct contact with food, and both the bottle and the cap are certified. Besides cosmetics, it is therefore also suitable for homemade oils, herbal syrups, infusions or fruit liqueurs. Both components are also declared suitable for contact with cosmetic products.

What the set is suitable for

• Oils and oil extracts – glass does not react with them, does not absorb scent or colour, and the dark shade slows the yellowing of oils in light.
• Hydrosols and aqueous bases – glass can be washed thoroughly and disinfected repeatedly, which matters more with water-based contents than with anhydrous ones.
• Tinctures and alcohol extracts – alcohol does not harm glass, even during long-term storage.
• Liquid soaps and shampoo bases – a working supply from which smaller bottles with a pump or sprayer are filled.

Nominal and total volume

The figure of 1000 ml is the nominal volume, that is, the quantity the bottle is intended to hold under normal filling. The physical volume up to the neck is larger. The difference provides a margin for the closure and for the expansion of the contents when the temperature changes, for example when oil warms up in the sun or a tincture is moved from the cold into the warmth. Fill the bottle up to the nominal volume. If you fill it to the brim, the contents will overflow when you close it or reach the thread when they warm up.

What to know before first filling

Before first use, wash the bottle and the cap in warm water with a cleaning product, rinse them and disinfect the inside with isopropyl alcohol or ethanol. Then leave the packaging open until it is completely dry, as residual water would introduce moisture into an oil or anhydrous base. Repeat the procedure for repeated filling, especially if the type of contents changes.

The black low cap screws onto the neck thread and closes the bottle without a dispensing element. The contents are poured out or taken with a measuring cup, which suits a one-litre volume better than a dropper or a pump. If you combine the bottle with another closure of the same neck type, we recommend checking the seal with your specific formulation. Further closures and ready-made combinations for this neck type are available in the Handymade range.
