Before fitting the dropper, check that the bottle has a compatible neck and that it is clean, dry and free of product residues on the thread. Place the dropper vertically onto the neck and tighten with an even, firm but not excessive tightening. Then turn the bottle upside down and briefly shake it over a suitable surface to verify whether there is any leakage in the area of the thread or the mechanism.

The dropper can be reused as long as it is not mechanically damaged and the dosing mechanism works flawlessly. When reusing, it is essential to observe hygiene principles – before each new filling, the packaging and the dropper must be thoroughly cleaned and disinfected. For disinfection, we recommend using alcohol-based products, for example isopropyl alcohol or ethanol, which are available on Handymade: IPA 99 % isopropyl alcohol and Ethanol 96 % denatured plant-based. After disinfection, allow all parts to dry thoroughly so as to avoid dilution or affecting the stability of the final product.

When selecting a bottle, we recommend using the filter by neck type in the relevant packaging category and choosing a variant with the same designation as the dropper. In the product descriptions, you will also find pre-prepared combinations of bottles and closures that are tested and functional. For custom combinations, however, it is always important to carry out a compatibility test – check sealing, the comfort of pressing the push mechanism and dosing accuracy with the specific formulation.

If you decide not to reuse the dropper, we recommend emptying it of product residues before disposal and wiping it with absorbent paper. The method of recycling is governed by the material composition stated in the product parameters – according to this, you will place the dropper in the appropriate sorted waste stream (for example plastic, metal or composite material). In the case of composite materials or if in doubt, it is advisable to follow local waste-sorting rules or hand the packaging over to a collection yard. By taking into account the information in the parameter table on the product page, you will ensure the most environmentally friendly recycling possible.

To select suitable packaging, you can use the advanced filter located at the top of the page after clicking on a specific packaging category. In the advanced filter, you can clearly select parameters such as neck type, size, colour and material, which allows you to quickly find compatible bottles, vials, jars or closures for your product. By combining these filters, you will tailor the selection so that it meets the technical requirements of your formulation as well as the visual style of your brand.
