Uranin

In order to track underground water courses and locate leaks in leaking house walls, fluorescent marking substances are used. Uranine has been used for almost a hundred years for this purpose. And from now until the end of the month, it’s on SPECIAL OFFER!

Uranine powder usually has a dark red colour, even when it is highly concentrated in water, and does not fluoresce. Only when it is heavily diluted does the powder fluorescently change the water to a yellow-green to green colour. UV radiation makes the effect even more strongly visible. Even the smallest amounts possess an enormous colouring capacity; therefore, less than 1 g of uranine is enough to fluorescently colour 1000 l of water green. Around 500 g of uranine can intensely colour sea areas of approximately 4000 m2 .

Ever since it was discovered 100 years ago that, when diluted, even the smallest quantities of this artificially produced substance can colour the largest volumes of water, it has been used as a marking agent to investigate subterranean water flows. In addition, uranine is highly suitable as a fluorescent dye for rendering leakage points visible in leaking waste water pipes, on flat roofs and in damp basements, or for testing for leaks in walls, pipes or tank systems. This is because uranine leaves hardly any deposits on rock surfaces, hardly ever leaves marks on non-absorbent construction materials and decomposes within a few days when exposed to daylight.

That’s how you can track any water course

On SPECIAL OFFER until the end of the month: Order 100g of uranine forjust £18.65 incl. VAT – now in our Trotec shop!
