Yes, the packaging can be used repeatedly if hygienic principles are observed. Before each new filling, the bottle and the dropper must be thoroughly cleaned and then disinfected with a suitable disinfectant, for example IPA 99 – isopropyl alcohol (/ipa-99-isopropyl-alkohol-1-l/ target="_blank") or 96 % ethanol denatured from plant origin (/etanol-96-denaturovany-rastlinny-1-l/ target="_blank"). Only after complete drying and evaporation of the alcohol is the bottle ready to be refilled.

Before first use, we recommend mechanically rinsing the bottle, removing any dust impurities and then disinfecting it with a suitable alcoholic solution, for example using IPA 99 products (/ipa-99-isopropyl-alkohol-1-l/ target="_blank") or 96 % ethanol denatured from plant origin (/etanol-96-denaturovany-rastlinny-1-l/ target="_blank"). After disinfection, allow the glass and the dropper to dry thoroughly at room temperature so that the residual alcohol completely evaporates, and only then proceed to filling the product.

To select a suitable packaging, we recommend using the extended filter after clicking on the relevant packaging category. It is located at the top of the page and allows filtering according to several parameters – especially according to the type and size of the neck, the size of the packaging, the colour and the material. Thanks to this, you can easily match the glass bottle with a compatible dropper, sprayer or screw cap so that it exactly suits your product and the required dosing method.

The dropper is ideal for concentrated and high-value formulations where precise and economical dosing is important. In practice, it is used mainly for facial serums, oils for face and body, blends of vegetable oils, active concentrates, aromatherapeutic oils and home or personal fragrances in concentrated form. It is also suitable for test and laboratory samples where you need stable and repeatable withdrawal of a small amount of product.

If you decide not to reuse the packaging, we recommend first emptying it and removing any product residues. The glass part of the bottle should be placed into sorted waste according to the rules for glass recycling given in the “material” parameter of the product. The dropper, which contains several material components, must be sorted according to the recommendations of the local waste collection system – if this is not possible, it belongs in mixed waste. By respecting the recycling rules given in the product parameter table on the Handymade website, you help reduce the amount of waste and improve the sustainability of your packaging.

Yes, this type of glass medicine bottle is often used also in the product development phase, in stability tests or in trial batches. The stability of glass as a packaging material helps to objectively evaluate the behaviour of the formulation over time. During testing, we always recommend monitoring the compatibility of the specific product with the used dropper or other closure – especially in terms of sealing, product viscosity and the required dosing speed.
