Glass bottle, vial, square straight, 10 ml

Glass bottle, vial, square straight, 10 ml is a small container made of amber glass for cosmetic and food products that require protection from light and a chemically resistant material. Amber glass reduces the penetration of daylight and thereby slows down light-triggered changes in the contents. This is particularly valuable for essential oils, fragrance blends, oil serums, tinctures, and concentrated active ingredients.

The square straight shape gives the bottle a stable stand and flat walls that hold a label well. The small volume makes it suitable for samples, travel sizes, test batches during formula development, or gift sets. "Vial" refers to the shape of the container, not its intended use.

Why choose this bottle

• Light protection – amber glass filters the portion of the light spectrum that accelerates oxidation of oils and fading of fragrant or coloured components. For light-sensitive products it is a better choice than clear glass.
• Chemical resistance of glass – glass does not react with essential oils, alcohol, solvents, or acidic extracts and does not release odours or plasticisers into the contents.
• Square shape – flat walls and edges allow more bottles to be packed tightly side by side in a box or drawer and make it easier to apply a label without creases.
• Food and cosmetic contact – the container has food-contact certification and a declaration of suitability for cosmetic products, so it can be used for both product categories.

Nominal and total volume

Nominal volume is the volume the bottle is designed for under normal filling conditions, and it is the volume by which the container is labelled and sold. Total brim-full volume is the physical capacity of the glass up to the neck and is slightly larger. The difference provides a reserve for the closure or dropper, which occupies part of the neck space once screwed in, and also allows for expansion of the contents with temperature changes.

What this bottle is suitable for

• Essential oil blends and fragrance compositions – the small volume limits contact with air; amber glass provides protection from light.
• Oil serums and facial oils – 10 ml is a common size for concentrated serums with a high proportion of active ingredients.
• Tinctures, herbal extracts, and alcohol-based extracts – glass resists alcohol and does not alter the taste or scent of the contents.
• Perfume oils and fragrance samples with a suitable closure.
• Food concentrates – homemade flavoured oils, vanilla extract, herb-infused oils for seasoning in small quantities.
• Samples and test batches – during formula development or when sending samples to customers.

For water-based products the small volume is an advantage, as the contents are used up quickly. However, preservation of the contents is governed by the formulation, not by the container.

Closures and ready-made combinations

The bottle is supplied without a closure. Closures with the same thread type as specified in the product parameters are compatible, and ready-made bottle + closure combinations are available in the Handymade range. With a custom combination we recommend verifying tightness and dosing with the specific formulation, as thick oils and thin alcohol-based solutions behave differently from a dropper or spray.

What to know before filling

Before first use, wash and sanitise the bottle with isopropyl alcohol or ethanol and leave it to dry completely with the neck facing down. Residual water in an oil-based product or fragrance blend will cause cloudiness and shorten the stability of the contents.

Glass is suitable for repeated use. After emptying, simply wash the bottle with warm water and dish soap — for oils, a pre-rinse with alcohol helps — and sanitise again. The closure, especially a dropper with a rubber bulb, wears out before the glass does, and we recommend replacing it when refilling.

Label dimensions are listed in the product parameters. The flat walls of the square shape allow a label to be applied without folding.
