Tamper Evident Glass Dropper, White, 57 mm

White dropper with tamper-evident ring, 57 mm

A dropper with a tamper-evident ring for bottles with an 18/415 neck dispenses liquid preparations precisely drop by drop and at the same time shows at a glance that the bottle has not yet been opened. It is particularly suited to facial serums, oil blends, tinctures and concentrated active ingredients that are applied in small amounts. The white cap with a white rubber bulb looks neutral and pairs well with amber, blue and clear glass.

The pipette tube is made of glass, the bulb of silicone and the threaded cap of polypropylene (PP). During normal use the bottle's contents therefore touch the glass tube, not plastic, which is an advantage with oil formulations and blends containing essential oils. The tamper-evident ring separates on first opening, so the customer of the finished product can see that the packaging is intact.

What the dropper is suited for

• Facial and oil serums – drop dispensing lets you take a few drops without spilling and without the fingers touching the contents.
• Tinctures and alcohol extracts – the glass tube tolerates blends containing ethanol well, and drop dispensing is standard for such preparations.
• Concentrated active ingredients and essential oil blends – for ingredients used in small amounts, a dropper is more practical than a spray or a pump.
• Finished cosmetic products for sale – the tamper-evident ring protects against unauthorised opening, which is an expected standard when selling serums and oils.

The packaging is suitable for use with cosmetic products. Food use is not declared for this cap, so use it only for cosmetic preparations.

Choosing the bottle and the right length

The dropper fits any bottle with an 18/415 neck. The neck type is always stated in the bottle's specifications. The length of the glass tube also matters: it should reach just above the bottom so that the remaining contents can be drawn out, but it must not rest against the bottom. You will find the dropper length in the name and in the specifications; when choosing, simply compare it with the height of the selected bottle. Bear in mind that bottles are quoted by nominal volume, the total volume to the brim is larger, and this reserve is taken up precisely by the submerged dropper tube. Ready-made bottle + dropper combinations with a verified length are available in the Handymade range. For your own combination we recommend checking the seal and dispensing with the specific formulation.

Good to know

Before the first filling, take the dropper apart into the cap with the bulb and the glass tube, wash it, disinfect it with isopropyl alcohol or ethanol and let it dry completely. The glass tube is fragile; handle it carefully when assembling and tightening the cap.

The silicone bulb is elastic and durable, but with prolonged contact with concentrated essential oils or solvents it may soften or change in volume. For this reason do not store a bottle fitted with the dropper upside down, and test blends with a high proportion of essential oils on a single sample over several weeks.

Reuse is possible if the dropper is thoroughly washed and disinfected. The tamper-evident ring is not restored after the first opening; on subsequent fillings the cap serves as an ordinary dropper without a first-opening indicator.

Recycling: the dropper is made up of several materials (glass, silicone, PP); take it apart before disposal and sort the individual parts separately.
