- Trace dye in water / sewage leaks
- Biochemical research
- Health care applications
- Air Sea Rescue
- A fluorophore in microscopy.
- Uses in river systems
- In a type of dye laser as a gain medium.
- Oilfield application
- In forensics and serology to detect latent blood stains.
- In yellow smoke devices.
- For tracing the direction of flow of water or to where a drain pipe runs, the recommended dilution rate is approx. 20g to 1 litre of water.
- The liquid is then used at a rate of 150ml-250ml per 500 litres of drain water, depending on the ground conditions.
- Approx. 100g of drain dye will treat 12,000 litres at 150ml per 500 litres and up to 8,000 litres at 250ml per 500 litres of drain water
- Fluoresces under black light.
- Does not require UV light.
Fluorescein is a fluorescent dye which is used in a number of different applications in sciences and medicine. In pure state, fluorescein is a red or orange powder which is dissolved in alkaline solutions to make up a yellow solution which will glow green.
In medicine, this compound has a broad range of uses. Ophthalmologists use it in eye exams, staining the eye with the dye to look for signs of tears in the cornea.
