Amber Glass Bottle, Type B, Slim, Black Cap, 10 ml

This is a ready-made set for small quantities of sensitive liquids: a type B glass vial in a tall, slim shape with a nominal volume of 10 ml and a simple black plastic screw cap. Brown glass filters light penetration, making the set especially suitable for contents that light gradually degrades – essential oils and their blends, fragrance compositions, oil serums, tinctures, and concentrated active substances. The small volume is also practical for samples, trial batches, and travel packaging.

The set is declared suitable for contact with cosmetic products. The glass vial alone has a certificate for direct food contact; the set as a whole – the vial with this cap – is intended for cosmetics.

Why choose this set

• Light protection – brown glass absorbs a large portion of light, which accelerates the oxidation of oils and the fading of fragrances. The contents therefore remain stable for longer, even when stored on an open shelf.
• Non-reactive material – glass does not absorb the contents, does not transfer the scent of a previous fill, and does not react with essential oils, alcohol, or most solvents. It is therefore suitable for concentrated and aromatic contents that would cause plastic to soften over time.
• Simple closure without dispensing – the cap seals the vial tightly and the contents are poured or drawn out. Suitable for storage, transport of samples, and contents that the customer doses themselves.
• Tall slim shape – the vial takes up little space, fits comfortably in the hand, and the narrow neck slows the evaporation of volatile components when opened.
• Reusable – glass withstands thorough washing and disinfection, so the vial can be filled repeatedly.

What contents it is suitable for

The set is designed for liquid and low-viscosity fills: pure essential oils and their blends, fragrance oils, face and nail oil serums, alcoholic tinctures, hydrosols in travel packaging, or concentrates of active substances dosed by drops. With aqueous contents, keep in mind that the packaging does not ensure stability – the formulation must be preserved.

Thick creams and butters are difficult to fill into the vial and hard to remove through the narrow neck; a jar is more suitable for these. For products intended for drop-by-drop dispensing directly during application, a combination with a dropper is more practical.

Nominal volume and fill-to-rim volume

For every container, we distinguish two volumes. The nominal volume is the quantity the container is designed for during normal filling. The total fill-to-rim volume is the physical volume up to the neck and is slightly larger. The difference is an intentional reserve: space for the cap or dropper, an air gap, and room for expansion of the contents with a temperature change. The vial should therefore be filled to the nominal volume, not to the brim – an overfilled vial will overflow during closing and the contents will get onto the thread, where it sticks and seals poorly.

How the closure seals and what to check

The cap is a plain polypropylene screw cap with a foam polyethylene sealing insert that seats against the neck rim. It is tightened by hand, not by force – excessive tightening deforms the insert and sealing performance deteriorates. With concentrated essential oils and solvents, it is advisable to leave the filled vial lying on its side for several days and check whether the insert has absorbed liquid or softened.

The vial has a neck with the thread type listed in the parameters; closures with the same thread type – droppers, sprayers, or other caps – and ready-made combinations are available in the Handymade range. With your own combination, we recommend verifying the seal, dispensing performance, and container behaviour with the specific formulation.

Preparation, cleaning, and labelling

Before the first fill, wash the vial, disinfect with isopropyl alcohol or ethanol and leave it to dry completely upside down – residual water in oil-based contents promotes microbial growth. The same applies to repeated use. The cap with its insert absorbs scent from strongly aromatic fills; when changing the contents, it is therefore better to replace it with a new one.

The straight cylindrical wall of the vial labels well. For small containers, a narrow label around the circumference or a tag on the cap works well.

The glass vial belongs in glass recycling and the plastic cap in plastics – separate them before disposal.
