Czarna nakrętka do butelek DIN18, uszczelka, bez zakraplacza

I have some little bottles whose lids broke, and thought these would work. But I think they need the special dropper ones, they're essential oil bottles. That's all right, I'm sure I'll find a use for them.

The18 bottle cap screws on very well, I have had no problems with dilutions in alcohol, but of note I don't use the seal before I screw it on the bottle I take it off and recycle it (I don't need the seal, I would like a version without the seal so I don't waste plastic).

I was very happy that these caps are also sold separately because I was able to recycle a lot of bottles, bottles that I had left over from various ingredients.

Skønt med produkter, hvor prisen er så lav, at man kan købe et ordentligt lager hjem og have til at ligge. De fungerer perfekt!

Jeg har altid en stor stak ekstra låg liggende i skuffen. De er så billige, at jeg bare smider de brugte ud og tager en ny - til den pris kan det ikke betale sig at rengøre og rense dem til genbrug.

This cap is ok for sealing some bottles that contain essential oils or other oils, but when it comes to solutions diluted in alcohol, they are not airtight enough. In some cases it seals well, but in general, if a bottle has small imperfections or the stopper in turn has small imperfections it changes things for the worse. For situations of substances diluted in alcohol I would suggest to bring for sale a cap model called in English Phenolic Caps with Polycone Liner.

They are sturdy but the seal doesn't stay after screwing completely, when you unscrew the cap the ring is still attached to the cap, I would have liked it to stay, that way it shows the bottle was left unsealed from sealing.

I have recently purchased these caps together with Gl 18 10ml bottles. they are good caps, firm, screw on well, warranty ring gives it a nice touch. comes very nicely screwed on a 10ml bottle.
