Amber Glass Bottle, Glossy Silver Dropper, 15 ml

Glass bottle, dropper bottle, silver glossy dropper, 15 ml

Brown glass and dropper in one complete set, ready for filling small doses of facial serums, oil blends and tinctures. Dark glass reduces light that accelerates the degradation of oils and the breakdown of sensitive active ingredients. The dropper dispenses contents drop by drop without spilling. The nominal volume of 15 ml is sufficient for a trial batch, travel packaging or a concentrated product used in small amounts.

The set is declared as suitable for contact with cosmetic products. The corresponding declaration is included with the product.

How the set works

The bottle has the shape of a dropper bottle with a narrow neck and an 18/410 thread. The dropper consists of a glass tube, a silicone bulb and a cap with a shiny silver aluminium sleeve that seals against the neck when tightened. The tube reaches almost to the bottom, so the last of the contents can be drawn up without tilting the bottle.

Pressing the bulb draws a small dose into the tube, which can be precisely repeated. The contents do not come into contact with hands.

What the set is suitable for

• Facial and hair serums – water-based and oil-based, where dosing by drops is expected.
• Oil blends for the face and cuticles – the small volume is used up before the oil has time to go rancid.
• Diluted essential oils and fragrance concentrates – glass does not react with the contents and does not absorb odour.
• Tinctures and alcohol extracts – for longer storage we recommend verifying the dropper's behaviour with the specific formulation.
• Samples and test batches – small volume for formula development or distributing samples to customers.

Nominal and total volume

Nominal volume is the quantity the bottle is designed for during normal filling. Total brim volume is the physical volume up to the neck and can be found in the specifications. The difference between them forms a reserve for the dropper tube, which takes up part of the space when closed, and for the expansion of contents with temperature changes. The bottle should therefore be filled to the nominal volume, not to the brim. If overfilled, the contents would overflow through the neck after inserting the dropper and contaminate the thread.

Good to know

Before the first fill, wash both the bottle and the dropper, disinfect with isopropyl alcohol or ethanol and leave to dry completely. Residual water in the tube would dilute anhydrous preparations and increases the risk of microbial contamination in aqueous formulations.

Glass tolerates hot water and alcohol disinfection, but not sudden temperature changes. Do not place a hot bottle on a cold surface and do not fill it with a boiling phase. Let it cool down to at least a temperature at which it can be held in the hand.

The set can be used repeatedly. When changing the contents, disassemble the dropper, rinse the tube and bulb and leave to dry, so that residues from the previous formulation do not transfer to the new one.

Caps with the same neck type and other ready-made combinations of this bottle with a closure can be found in the Handymade range. For a custom combination, we recommend checking the seal with the specific formulation.

After emptying and rinsing, the bottle belongs in the glass recycling.
