Gloss Black Glass Bottle, Glossy Silver White Pump, 50 ml

Glass bottle with pump dispenser, black glossy, 50 ml is a ready-to-fill set consisting of a black glass vial and a white-silver plastic pump, ready to fill without searching for a suitable closure. Opaque black glass protects the contents from light, and the pump dispenses a small, well-controlled amount with each press. The set is therefore best suited for serums, facial oils, light emulsions and liquid foundations, which are applied in small doses and need to maintain their quality for longer. The entire set is declared as suitable for contact with cosmetics.

The glossy black bottle with a light-coloured pump creates a striking contrast on the shelf, but the main reason to reach for it is practical. The contents are not exposed to light or an open neck during use, and only as much as needed is dispensed each time.

What the set offers

• Light protection – black glass does not let light through, which benefits serums and oils with light-sensitive ingredients such as vitamin C and its derivatives, retinoids or unsaturated vegetable oils, which turn yellow more quickly in light.
• Hygienic dispensing – the product is not removed by fingers or poured through the neck. The pump draws the contents up through a dip tube from the bottom and pushes it out, while the rest in the bottle remains sealed and less contaminated.
• Precise small dose – one press releases a fraction of a millilitre. For concentrated serums and oils this is an advantage: you can estimate the dose by the number of presses and the product does not spill.
• Glass that does not react with the contents – glass does not react with oils, essential oils or alcohol. For more demanding formulations, simply check the behaviour of the plastic parts of the pump.
• Matched closure and bottle – the neck of the vial and the thread of the pump fit together, so you do not need to worry about closure compatibility. Additional closures with the same neck type, listed in the product parameters, are available in the Handymade range.

Nominal and total volume

With this bottle you will encounter two volumes. Nominal volume is the quantity the container is designed for during normal filling, and this is the figure stated in the name. Total volume to the brim is the physical volume up to the neck. The difference between them is a margin for the dip tube and the pump body, which push part of the contents upward when screwed in, and for expansion of the contents when the temperature changes. Both values are listed in the product parameters.

Suitable for products such as

• facial serums – water-based and oil-based, especially those with active ingredients sensitive to light and air,
• facial and body oils and oil blends for face massage, dispensed a few drops at a time,
• light emulsions and fluids – liquid moisturisers, leave-on products for day and night,
• liquid foundation and primer bases, where a small and repeatable dose matters,
• hair serums and split-end oils with low viscosity.

The set is not intended for thick creams, butters, gels with high viscosity or products containing particles (scrubs, pigments in suspension). The dip tube draws in liquid content; a dense substance will not pass through it or will clog the pump.

Good to know

Preparation before first filling. Wash the bottle, disinfect with isopropyl alcohol or ethanol and allow to dry completely. Rinse the pump and let it dry without heating; the plastic and aluminium parts are not suitable for heat sterilisation. Glass tolerates higher temperatures, but do not subject it to sudden changes, such as hot water immediately after cold storage.

First presses. A new pump needs to be primed: the first presses draw the product up through the dip tube, and only then does it begin to dispense. This is normal behaviour, not a fault.

Viscosity of the contents. The pump reliably handles water-based serums, oils and light emulsions. With a thicker emulsion, we recommend verifying before filling an entire batch that the pump dispenses it evenly and that the dose does not decrease.

Residue at the bottom. The dip tube reaches almost to the bottom, but the pump cannot draw up the last amount below its tip. With concentrated serums, it is worth removing the residue after unscrewing the pump.

Opaque bottle. The level cannot be seen through the black glass. In own production, it has proved useful to note the filling date on the label and to weigh the full bottle so you can estimate how much content remains.

Alcohol-based contents and essential oils. Glass is fully compatible with these. For products with a high proportion of alcohol or undiluted essential oils, we recommend checking the pump's behaviour after a few weeks, as the plastic seals and dip tube may change properties with such contents.

Transport. The pump is a dispensing closure, not a transport closure. Before dispatching finished products, verify the seal with the specific formulation, transport bottles upright and, for sensitive contents, provide protection against compression of the pump head.

Labelling. A light-coloured label or light-coloured print stands out on the glossy black surface.

Recycling. The glass bottle belongs in glass collection. The pump contains both plastic and aluminium; separate it from the bottle before disposing of it.
