Matte black dropper with glossy stripe, plastic, 84 mm

A dropper with a black matte cap and a glossy stripe is used for dispensing thin liquids drop by drop. It is suitable for facial serums, oil blends, alcohol extracts, and active ingredients that are measured in small quantities.

It consists of a glass tube, a silicone bulb, and a threaded plastic cap. The part in permanent contact with the contents is primarily glass, which does not alter the scent or colour of the filling. The dropper is suitable for contact with cosmetic products. The black matte cap complements amber, clear, and coloured glass.

What products is the dropper suitable for

• Serums and concentrates – both water-based and oil-based serums are applied drop by drop, so there is no waste.
• Facial and hair oils – the tube draws up oil without it running down the neck and label.
• Alcohol extracts – glass is resistant to ethanol and the liquid can be measured drop by drop.
• Raw materials in a home workshop – the dropper makes it easier to measure liquid active ingredients, colorants, or fragrance components in small amounts.

The dropper is not suitable for thick gels, emulsions, or creams. The tube does not draw them up evenly and the contents remain inside. For such textures, a pump dispenser is more practical.

How to choose the right length and neck size

When choosing a dropper, two things matter: the thread type and the tube length. The thread must match the bottle neck, otherwise the cap will not seal or cannot be tightened. This dropper fits bottles with an 18/415 neck.

The length should be such that the end of the tube reaches just above the bottom. A shorter tube will not draw up the remaining contents. One that is too long will press against the bottom, the cap will not seat properly, and the glass may crack.

Bottles with the same neck type and ready-made bottle-and-dropper combinations are available from Handymade. For a custom combination, we recommend verifying the seal, dispensing behaviour, and dropper performance with the specific formulation.

Filling the bottle and volume headspace

Every bottle has two volumes. The nominal volume is the quantity the container is designed for at standard fill. The total volume is the physical capacity up to the rim of the neck. The difference between them provides headspace for the dropper tube and for expansion of the contents with temperature changes. Fill to the nominal volume, not to the brim. In an overfilled bottle, the tube will displace some of the contents and it will leak through the thread onto the neck and label.

What is worth knowing

• Preparation before first use – wash the dropper, disinfect with isopropyl alcohol or ethanol, and leave to dry completely. Draw the disinfecting solution in and release it several times to rinse through the tube and the inside of the bulb.
• Changing the filling – silicone may retain the scent of strongly fragranced products. Bear this in mind if you use the dropper on a different filling after cleaning.
• Handling glass – the tube has thin walls. Avoid knocking it against the bottle neck and sudden temperature changes, such as rinsing with cold water immediately after hot.
• Recycling – the dropper consists of three materials that are sorted separately once disassembled: glass, silicone, and plastic.
