Pipettes for 10 ml bottles DIN 18

My experience with these pipettes is very good. I know they are discussed controversially within the DIY community but I had only one case where the bulb decomposed (boswellia dilution in high concentration).
Just don’t use it as long term storage solution and you will be fine (and neither having to deal with corrosion nor evaporation).
When you are considerate about the amount of waste you produce while mixing, these glass pipettes are a neat option.
