Product description
This 50 ml amber glass medicine bottle with a dropper insert and a tamper-evident cap is designed for thin liquids that are dispensed drop by drop: essential oils and their blends, fragrance oils, alcoholic plant extracts, oil serums or liquid active ingredients. The amber glass protects the contents from light.
The clear plastic dropper insert fits into the neck and releases the contents only when the medicine bottle is tilted. The black ribbed cap has a tamper-evident ring that separates on first opening, so it is immediately visible whether the medicine bottle has already been opened. The set is suitable for contact with cosmetic products.
What it is suitable for
- Essential and fragrance oils – dispensing drop by drop, both during production and when using the finished blend.
- Alcoholic plant extracts – thin contents drip quickly.
- Oil serums and blends of vegetable oils – thinner oils drip smoothly, thicker ones more slowly.
- Liquid active ingredients – a stock of the raw material from which small amounts are taken for a formulation.
The set is not suitable for creams, gels and thick emulsions, as they will not pass through the dropper insert.
Dispensing and closing
Drop size and dripping speed depend on the viscosity of the contents, so it is worth testing the dispensing first with each liquid.
The medicine bottle is filled without the dropper insert. After filling, the dropper insert is pressed into the neck and the medicine bottle is closed with the cap. The tamper-evident ring is single-use. After the first opening it stays separated and the cap then works as a standard screw closure.
The weight of a drop differs between contents. If you need to dose precisely by drops, weigh a larger number of drops of the specific liquid and calculate the weight of a single drop.
Nominal and total volume
The nominal volume of 50 ml is the amount the medicine bottle is designed to hold with normal filling. The total brimful volume, stated in the parameters of the medicine bottle, is larger and shows how much fits in up to the rim of the neck. The difference provides a reserve for the dropper insert, which extends into the neck.
It should therefore be filled only up to the nominal volume. If the medicine bottle is filled to the brim, the contents will overflow when the dropper insert is fitted.
Good to know
- Preparation before first filling – wash the medicine bottle, dropper insert and cap, disinfect them with isopropyl alcohol or ethanol and let them dry completely.
- Plastic parts – the dropper insert is made of PP and the cap of HDPE. With concentrated essential oils and solvents, we recommend testing on a sample how the plastic behaves during longer contact with the specific contents.
- Other closures – closures with the same neck finish (stated in the parameters) and other ready-made combinations are available in the Handymade range. If you make your own combination, we recommend checking the tightness, dispensing and behaviour of the packaging with the specific formulation.
Only the glass medicine bottle on its own has a food-contact certificate. The dropper insert and cap do not have it, so the set as a whole is intended for cosmetics.
