Uranine (Uranin) is used to colour water so that you can see the path that water takes. This is best done under UV light, so we recommend our UV lamp (UV-Lampe) for this purpose.
For easy dosing, we supply a laboratory spoon with two spoon sizes. The dosage is described in detail in our instructions. The 50 grams of Uranin are sufficient for approx. 5000 litres of coloured water.
