Hello everyone! I send in advance that I use the isopropanol for my Lampe Berger. Either for diluting flavorings, as well as to vaporize the pure isopropanol. From this use advises "Lampe Berger" Although from because while the burner could be damaged. However, I personally use the isopropanol for a long time for just this purpose, because the fluids of Lampe Berger is exactly the same bottom line, and have never had problems with a defective burner. This is a really good, low-priced and pure isopropanol. Both the shipping, the product itself, as well as the contact to the seller is really perfectly !! Gladly again and 5 stars from me!
