Amber Round Sirup Glass Bottle, 28 mm, White Pump, 50 ml

Amber glass medicine bottle, white pump, 28 mm, 50 ml

An amber glass medicine bottle with a white pump that dispenses the contents in measured doses and also protects them from light. Amber glass reduces the amount of light that gets through, so it suits formulations with oils, vitamins or plant extracts, which lose stability in light. Each press of the pump delivers approximately 1 ml, which is enough for one application of serum, facial oil or a light emulsion. The contents also do not come into contact with fingers or air, as they would with an open neck.

The 50 ml volume corresponds to a common pack size for facial serum, fluid, liquid make-up, cleansing oil or a travel-size hand cream. The set as a whole is intended for cosmetics. The glass bottle on its own has a certificate for direct food contact; the pump does not have such approval.

What the set is suitable for

• Serums and fluids – both water-based and oil-based, liquid to slightly thick, dispensed by the drop or in small amounts.
• Facial and body oils – the pump measures out one dose without pouring.
• Light emulsions – facial milks, fluids with SPF, hand creams with lower viscosity.
• Cleansing oils and liquid make-up removers – the contents stay enclosed and can be dispensed with one hand.
• Samples and test batches – for checking a formulation before larger production.

Thicker creams, butters and products with solid particles, for example scrubs or suspensions with pigment, may clog the pump or may not be drawn up at all. For borderline viscosity, we recommend testing the behaviour with your specific formulation.

Nominal and total volume

The nominal volume is the amount the bottle is designed for under normal filling. The brimful capacity, given in the parameters, is the physical volume up to the neck. The difference between them is a reserve for the tube and body of the pump, which push part of the contents upwards once inserted, and for the expansion of the contents when the temperature changes. Fill the bottle to the nominal volume, not to the brim. If you fill it up to the neck, the contents will overflow when you screw on the pump.

Good to know

Preparation before filling. Before the first filling, we recommend washing the glass and the pump, disinfecting them with isopropyl alcohol or ethanol and leaving them to dry completely. Residual water in the tube would dilute the first doses of the product and, in anhydrous formulations, may impair stability.

Filling temperature. Glass tolerates warm filling, but not a sudden change in temperature. Do not pour a hot emulsion into a cold bottle or the other way round. The pump is fitted only onto cooled contents, so that the plastic parts do not deform and no vacuum forms in the closed bottle.

Compatibility with the contents. Glass is resistant to cosmetic raw materials, while the pump has plastic parts. For formulations with a high proportion of essential oils, alcohol or solvents, we recommend leaving a filled set to stand for several weeks before larger production. Check that the seal holds, whether the plastic changes colour and whether dispensing stays smooth.

Reuse. After thorough washing and disinfection, the bottle can be used again. Before the next filling, rinse the pump with warm water and a cleaning product. Then pump clean water through it several times, followed by air, so that no residue of the previous product remains in the mechanism. If the dispensing starts to stick, replace the pump.

Transport. The pump does not seal as tightly as a tightened cap. When shipping or travelling, we recommend checking that the contents do not leak when the bottle is tilted. For transport, you can use a cap and fit the pump only when the product is in use.

The bottle has a PP28S neck finish. You can find other closures with the same neck finish and ready-made combinations in the Handymade range. If you create your own combination, we recommend checking the tightness and behaviour with your specific formulation.

Recycling. Glass belongs in glass waste; before discarding, unscrew the pump and sort it as plastic.
