Fluorescein 40%

Fluorescein 40% – High-Visibility Tracer Dye

Fluorescein 40% is a fluorescent dye used to trace water flow, find leaks, and study how liquids move. It’s common in water treatment, leak detection, and environmental testing. The 40% concentration makes it easy to see, even when used in small amounts. It’s a good option for both industrial and environmental work in Australia.

It glows bright green under UV light, so it’s easy to track. People use it in hydraulic tests, pipeline leak checks, and research. It’s safe to handle, non-toxic, and won’t harm the environment.

What Is Fluorescein 40%?

It’s a water-based dye made from sodium fluorescein. It contains 40% active dye. This makes it very visible when tracing how water or other liquids move. Some countries call it sodium fluorescein.

It’s used in closed-loop systems, streams, and reservoirs. It’s a simple, cost-effective way to track water flow or do flow-related tests.

Where It’s Used

Fluorescein 40% is mostly used to trace water flow in pipes and rivers. Water companies and councils use it to find leaks and check pipe connections.

Environmental teams use it in rivers to see how water spreads and to test for pollution. It’s also used in HVAC systems and boiler tests in industrial settings.
