Fluorescein Sodium, uranine for underground water tracing, leak detection, etancheity test, infiltration testing
In the field of hydrology, thanks to its detection sensitivity and low tendency to adsorption, sodium fluorescein is widely used for mapping underground watercourses, checking hydraulic connections, transit and flow time studies, river flow measurements, infiltration water path studies, layer waterproofing checks, simulating the spreading of liquid substances....
It is also used for various network and pipe diagnostics, leak detection on roofs and terraces, as a colorimetric marker in the maritime safety field, for coloring chemical and maintenance products, for industrial penetrant testing, behavioral studies of insects and animals, the medical field, aquatic decoration, damage surveys...
