Glass Dropper, Glossy Black, 53 mm

Dropper black, glossy, 53 mm

Black glossy dropper, 53 mm seals a bottle with an 18/410 neck and simultaneously dispenses its contents drop by drop – no pouring, no contact with fingers. It is intended for facial serums, oil blends, tinctures and concentrated active ingredients, that is, products applied in small amounts where only a few drops are needed at a time. Only the glass tube is in permanent contact with the contents; the contents are drawn in by a black silicone bulb, and a glossy black collar fits onto the neck.

The glossy black finish pairs with amber, blue, frosted and black glass and fits into a cohesive visual line where the entire range is intended to look dark and minimal.

What it consists of and how it works

The dropper consists of three functional parts:

• Glass tube – the chemically inert part that is in permanent contact with the contents. Glass does not react with oils, alcohol or aqueous solutions and does not absorb scent or colour.
• Silicone bulb – squeezing and releasing draws the contents into the tube. Silicone is flexible and withstands repeated use, but should not be in prolonged contact with the contents.
• Threaded collar – a glossy black aluminium shell with an internal PP thread that ensures a secure fit on the bottle neck.

Dispensing is approximate. Drop size depends on the viscosity and surface tension of the contents, so the same number of drops of oil and an alcohol tincture does not correspond to the same volume. The dropper is not intended for precise dosing, but is suitable for everyday application of serum or oil to the skin.

Which bottles it fits

The dropper fits any bottle with an 18/410 neck. The second key factor is the tube length: it should reach just above the bottom of the bottle so the last of the contents can be drawn out, but must not rest on the bottom. This dropper is therefore suitable only for bottles of the appropriate height. Bottles with the same neck type and ready-made bottle + dropper sets are available in the Handymade range. For your own combination, we recommend verifying the length, seal and behaviour of the closure with your specific formulation.

Suitable for products such as

• Facial and hair serums – water-based and oil-based, where a few drops are applied to clean skin or into the palm.
• Oil blends and massage oils in small packaging – vegetable oils and their blends with essential oils, applied drop by drop.
• Tinctures and alcohol extracts – glass and PP are both compatible with ethanol and drop-by-drop dispensing is practical for concentrated extracts.
• Concentrated active ingredients and samples – small volumes added to a finished product or tested before larger-scale production.

The dropper is not suitable for thick creams, balms and gels – the contents cannot be drawn into the tube or do not flow out drop by drop.

Good to know

Bottle volume. Once tightened, the dropper occupies part of the internal space of the bottle. The bottle is therefore filled to the nominal volume, not to the brim. The margin between the nominal and total volume is reserved for the tube and for expansion of the contents with temperature changes.

Essential oils and concentrates. The glass tube does not react with them. The silicone bulb withstands normal use, but may soften or lose elasticity on prolonged contact with concentrated essential oils. Do not draw the contents up into the bulb.

Preparation before first use. Before first filling, we recommend disassembling the dropper, washing the tube and bulb, disinfecting them with isopropyl alcohol or ethanol and allowing them to dry completely. Moisture in the tube would introduce water into an oil-based product and with it the risk of microbial growth.

Reuse. The glass tube and collar can be reused after washing and disinfection. Check the bulb regularly – if it has lost elasticity or draws in weakly, replace the dropper.

Materials and contact with cosmetics. The packaging is suitable for use with cosmetic products and meets the relevant legislative requirements; a declaration of conformity is available with the product. The dropper consists of several materials (glass, aluminium, PP, silicone) and therefore does not count as single-material packaging for recycling purposes – the tube can be sorted as glass after separation.
