Clear Glass Bottle, 15 ml, 156 pcs

The glass bottle with a volume of 15 ml is intended for small quantities: samples of serums and facial oils, essential oil blends, fragrance oils, alcohol-based extracts or test batches during recipe development. Clear glass shows the colour and clarity of the contents. Customers can see what they are receiving, and during a stability test the maker will notice cloudiness or phase separation. It is sold as a whole tray of 156 pcs, which is enough for a series of samples, a workshop kit or a smaller production batch.

Glass does not react with alcohol, essential oils or vegetable oils, so the bottle can also be filled with concentrated blends that some plastics would degrade over time. The packaging is suitable for contact with cosmetic products. It suits both cosmetic grade and technical grade use, so it works equally well for a finished product and for samples of raw materials, dyes or fragrance compositions in the workshop.

Suitable uses

• Samples and testers – 15 ml is enough for a customer to try a serum, oil or toner. The same volume is also suitable for keeping a sample from each batch.
• Essential oil blends and fragrance oils – glass does not absorb the scent, and the concentrate does not damage it.
• Facial and nail oils, oil serums – a small volume is used up before the oil has time to oxidise.
• Alcohol-based extracts and preparations – a high alcohol content is no problem for glass.
• Test batches during recipe development – a small quantity saves raw materials, and clear glass shows any change of colour or cloudiness.

Volume and filling

The nominal volume of 15 ml is the volume the bottle is designed for in normal filling. The brimful capacity given in the parameters is the physical volume up to the neck. The difference forms a margin for the dropper or cap and for the expansion of the contents when the temperature changes. For this reason, fill to the nominal volume, not to the brim.

Caps, droppers and sprayers with an 18/410 neck finish, as well as ready-made bottle + closure combinations, can be found in the Handymade range. If you choose your own combination, we recommend checking the tightness, dispensing and behaviour of the packaging with your specific formulation.

Good to know

Clear glass does not protect the contents from light. For samples and products that are used up quickly, this is not a problem. For longer storage, keep oils prone to oxidation, essential oils or vitamins in the dark, in a box or in a drawer. Amber or blue glass is more suitable for the long-term storage of sensitive substances.

Before the first filling, wash the bottles, rinse them, disinfect them with isopropyl alcohol or ethanol and leave them to dry completely. Residual water in an anhydrous product, for example in an oil or an oil serum, can spoil the contents.

Glass does not tolerate sudden changes in temperature. A hot product poured into a cold bottle may crack it, so let the product cool before filling or warm the bottles beforehand. After use they can be washed and filled again, and the scent of essential oils is removed from glass more easily than from plastic. An empty bottle without its closure belongs in glass recycling.
