Glass Dropper, Glossy Silver, 59 mm

Silver glossy dropper with 18/410 thread seals the bottle and dispenses its contents drop by drop. Suitable for facial serums, oil blends, tinctures and concentrated active ingredients where precise dosing matters and the contents should not be poured out or touched by fingers. The glossy silver cap gives the bottle a neat appearance without affecting the closure function.

The dropper consists of a threaded plastic cap, a glossy aluminium sleeve, a silicone bulb and a glass tube. Glass is non-reactive to common cosmetic contents, making this dropper suitable for blends with essential oils or alcohol extracts, where a plastic tube might eventually change colour or shape.

Why choose this dropper

• Precise dosing – contents are dispensed drop by drop or by the full tube, making it easier to apply serums and concentrates as well as to measure oils during formulation.
• Hygienic use – contents are neither poured out nor in contact with the neck, so fewer impurities enter the product.
• Glass tube – a non-reactive material that does not absorb fragrances or colorants and can be thoroughly cleaned.
• Glossy silver cap – suitable for gift and retail packaging where the container should look polished; functionally identical to standard droppers of the same thread size.
• Standard 18/410 thread – fits bottles with the same neck type, so the dropper can be paired with different volumes and glass colours.

How to choose and fit the dropper

Two details are decisive: thread type and dropper length. The bottle must also have an 18/410 thread; otherwise the dropper will not seal or cannot be tightened. Length is chosen according to the bottle height: the tip of the glass tube should end just above the base so the remaining contents can be drawn up, but it must not touch the base or bend when the cap is tightened.

When assembling, screw the dropper onto the neck and tighten by hand. Excessive force will not improve the seal and may damage the thread or the glass tube. Before shipping by post, check the seal of the assembled unit by laying it on its side and turning it upside down.

Suitable contents

The dropper with a glass tube works well for oil serums and carrier oil blends, for aqueous and gel serums with lower viscosity, for tinctures and alcohol extracts, for concentrates of active ingredients dispensed drop by drop, and for essential oil blends intended for dilution.

Less suitable for thick emulsions and creams that the tube cannot draw up, and for products containing solid particles that would catch in the narrow tip. With heavily thickened gels, test the suction before filling a larger batch.

What is good to know

Before first use, wash and disinfect the dropper with isopropyl alcohol or ethanol and allow to dry completely. The glass tube and silicone bulb can be disassembled and cleaned separately. The dropper can be used repeatedly, but before each new fill check the glass for cracks and confirm the bulb still holds suction.

When labelling, note that the glossy metal sleeve covers only the cap; the label is applied to the bottle, not to the dropper. The dropper is suitable for use with cosmetic products; the declaration of conformity is available with the product.

This is multi-material packaging. When recycling, separate the glass tube from the plastic and metal parts and sort them individually.
