Amber Glass Bottle, Gold Black Dropper, 100 ml

This amber glass 100 ml medicine bottle with a black and gold dropper is a ready-to-use set for filling facial serums, oil blends and tinctures that are dispensed drop by drop. The dark glass reduces the amount of light reaching the contents, so the bottle is particularly suitable for blends containing vegetable and essential oils or light-sensitive active ingredients. The dropper with a glass tube lets you draw exactly as much as the recipe or application requires.

The set is declared suitable for contact with cosmetic products. Only the glass bottle on its own has a certificate for direct food contact; the dropper does not, so the assembled set is intended for cosmetics.

What it is suitable for

• Facial and oil serums – the dropper dispenses one drop at a time, which makes precise application of concentrated products easier.
• Essential oil blends and fragrance compositions – drop-by-drop dispensing simplifies measuring into recipes, and the dark glass slows the effect of light.
• Tinctures and alcohol extracts – both the glass bottle and the glass tube of the dropper tolerate alcohol, and the drops can be counted.
• Macerated oils and treatment oils for hair or nails – drop-by-drop dispensing is more precise than pouring from the neck.

Volume and filling

The nominal volume of 100 ml is the volume the bottle is designed to hold when filled normally. The brimful volume given in the parameters is the physical volume up to the neck. The difference between the two serves as a reserve for the glass tube of the dropper, which pushes the level up when screwed in, and for the expansion of the contents with temperature changes. The bottle should therefore be filled to the nominal volume, not to the brim.

Using the dropper

The length of the dropper is matched to this bottle. It consists of a glass tube, a silicone bulb and a black and gold closure that screws onto the neck with an 18/410 neck finish. To draw the product, squeeze the bulb above the liquid level, immerse the tube and release the bulb so that it fills. Squeezing the bulb above the liquid level prevents the contents from getting into the bulb, where they are difficult to clean out.

More viscous oils and serums with a thickener are drawn up more slowly and the drops are larger. With such formulations, it is worth testing the dispensing before filling the whole batch.

Good to know

Glass tolerates washing with hot water but does not tolerate sudden temperature changes. Do not pour hot contents into a cold bottle or the other way round. After thorough washing and disinfection, the bottle can be used repeatedly. With the dropper, it is advisable to check after each emptying whether the silicone bulb has hardened or cracked.

The bottle can also be fitted with other closures with the same neck type, which are available in the Handymade range together with ready-made combinations of bottle and closure. If you create your own combination, we recommend checking the tightness and dispensing with your specific formulation.

After use, the glass belongs in glass recycling. The dropper is made of several materials, so before disposal, separate the glass tube from the plastic closure and the silicone bulb.
