Uses for Fluorescein dye
- Water tracer – detectable at very low levels. Used for effluent monitoring.
- Dye used in the Chemical industry. especially useful for -colouring detergents and degreasers etc. – stable in high alkaline conditions.
- Used to determine sensitivity of fluorometers.
Fluorescein Sodium Dye is a recognised and approved tracer dye used by water authorities. It is used at low levels of 1kg per million litres of water (i.e. 1ppm) which permits visual determination of water flow. At these levels it is not considered to be harmful to fish.
