Amber Boston Round Sirup Glass Bottle, PP28S, 1000 ml, 20 pcs

The 1000 ml amber glass Boston medicine bottle is used to store larger quantities of liquid raw materials and finished products. Amber glass lets through less light than clear glass, so it protects the contents from the effects of light. It is particularly suitable for vegetable oils, hydrosols, tinctures and toners, whose ingredients gradually change when exposed to light. The Boston shape has rounded shoulders and a narrower neck, from which the contents pour smoothly into smaller bottles.

The bottle is of European origin and is supplied in a pack of 20 without closure. The packaging material is suitable for use with cosmetic products and is also approved for direct contact with food.

What it is suitable for

• Stock bottle for oils and hydrosols – a larger volume pays off with raw materials that are used continuously across several batches.
• Tinctures and alcohol extracts – glass does not react with alcohol or essential oils, so concentrated extracts can be left to macerate for longer.
• Intermediate products in production – a prepared water phase, a mixed oil phase or a finished toner before it is filled into retail bottles.
• Home food storage – oils, syrups and herbal extracts, thanks to the food-contact certificate.
• Larger packs for customers – refills or large-volume packs of body oils and toners, which the customer decants into smaller packaging at home.

Nominal volume and filling

Nominal volume is the volume the bottle is designed for in normal filling. The brimful volume is the physical volume up to the neck opening and is usually higher. The difference provides a reserve for the closure and for the expansion of the contents with changes in temperature. Therefore, fill the bottle to the nominal volume, never to the brim.

Closures

The bottle has a 28/410 neck finish. You will find closures with the same neck type and ready-made bottle + closure combinations in the Handymade range. If you choose your own combination, we recommend checking the tightness, the way the product is dispensed and the behaviour of the packaging with your specific formulation, especially with alcohol-based and oil-based contents.

Good to know

Before the first filling, wash the bottle, disinfect it with isopropyl alcohol or ethanol and leave it to dry completely. Residual water would dilute oil-based contents and increases the microbiological risk in water-based products. Follow the same procedure before every further filling, as glass can be used repeatedly. When switching from an oil to a water-based product, we recommend washing with a degreasing agent.

Glass does not tolerate sudden temperature changes. Do not pour a hot water phase or a liquid straight from a water bath into a cold bottle; first let the contents cool to at least room temperature. Together with the glass, a full one-litre bottle is noticeably heavy, so place it on a stable surface when handling it.

At the end of its life, the bottle belongs in glass recycling.
