Green Glass Bottle, Matte White Dropper, 10 ml

The green glass bottle with dropper, 10 ml, is a set for dispensing liquid preparations drop by drop. The medicine bottle with an 18/410 neck finish is supplied together with a white matte dropper, so the packaging is ready for filling without searching for a closure. The coloured glass reduces some of the light reaching the contents, which you will appreciate with oil serums, essential oil blends and concentrates with light-sensitive active ingredients.

The 10 ml volume suits products that are used in small amounts and over a longer period: face oils and oil serums, essential oil blends for aromatherapy, alcohol tinctures, concentrated active ingredients for your own formulations, or samples for testing a new batch. The dropper lets you take exactly as much as you need, without pouring and without your fingers touching the contents.

What the set is suitable for

• Oil serums and face oils – glass does not absorb the scent or colour of oils, and dispensing by drops allows the oil to be applied sparingly.
• Essential oil blends – the small volume and drop-by-drop dispensing match how these blends are actually used.
• Tinctures and alcohol extracts – glass is resistant to alcohol, and the dropper makes dispensing into a toner or gel easier.
• Active ingredient concentrates – small amounts that are added to the water or oil phase during production are dispensed by drops without a measuring cup.
• Samples and test batches – 10 ml is enough to check stability and fragrance before making a larger quantity.

Filling and volume

Nominal volume is the amount the bottle is intended for under normal filling. Brimful volume is the physical volume up to the neck and you will find it in the parameters. The difference between them is a reserve for the glass tube of the dropper, which pushes part of the contents upwards when screwed in, and for the expansion of the contents when the temperature changes. For this reason, fill to the nominal volume, not to the brim.

The dropper combines a glass tube with a silicone bulb and a plastic PP thread. After filling, tighten the dropper by hand, without force. Overtightening may damage the thread and the seal.

Good to know

Before the first filling, wash the bottle and the dropper, disinfect them with isopropyl alcohol or ethanol and leave them to dry completely. Residual water in an oil or in an anhydrous product creates conditions for microbial growth. The same procedure applies when reusing the set. Glass withstands repeated washing, but with the dropper check the condition of the silicone bulb, which with some contents may change over time.

Do not expose the glass to sudden temperature changes. Hot contents poured into a cold bottle may crack the glass, so let the product cool to at least lukewarm before filling. With concentrated essential oils and blends with a high proportion of solvents, we recommend checking the behaviour of the bulb in the finished formulation over several weeks before you decide on a larger series.

The bottle is made of glass and at the end of its life belongs in glass recycling. The dropper combines several materials, so separate it from the bottle for recycling. You can find other closures with an 18/410 neck finish and ready-made combinations of packaging and closure in the Handymade range.
