Fluorescein 40%

Fluorescein 40% – High-Visibility Dye for Industrial and Laboratory Use

Fluorescein 40% is one of those quietly essential tools used across industries that rely on clarity and traceability. It’s a fluorescent dye — bright, unmistakable — that shows up boldly when you need it to. Whether it’s for tracing water flow or spotting the tiniest leak in a complex system, this liquid solution does the job with precision. As a trusted chemical supplier in Perth, we provide high-purity Fluorescein 40% tailored for high-visibility applications.

What Exactly *Is* Fluorescein?

Well, in scientific terms, it’s known as resorcinolphthalein, or D&C Yellow No. 7 — but honestly, most people just call it fluorescein. When exposed to UV or blue light, it gives off this incredibly vivid green fluorescence. And in its 40% liquid form, it becomes especially effective for applications where visual tracking really matters — dye tracing, leak tests, water movement studies, that sort of thing.

It’s water-soluble, glows brightly, and is flexible enough for both rugged industrial tasks and delicate lab experiments.

🧪 Fluorescein 40% Solution at a Glance

• Form: Aqueous solution
• Colour: Bright yellow-green in daylight; intense green glow under UV light
• Typical Uses: Tracer dye in hydrology, leak detection in tanks or pipelines, forensic tests, lab procedures
• Industries: Environmental studies, construction, plumbing, diagnostics, and scientific research

Even at low concentrations, Fluorescein 40% can be detected easily — which makes it perfect for tracing flow in drainage or sewage systems, pinpointing leaks in pressurized lines, or modelling pollution paths. It’s got this reliable presence that quietly gets the job done, even in murky conditions.

🏭 Real-World Benefits for Industry

In industrial settings, speed and visibility are everything — and this dye delivers both. It’s non-toxic at working concentrations, which is key for municipal or environmental use. Not to mention, it’s surprisingly cost-effective considering how efficient it is. Some standout benefits include:

• Excellent visibility, even in daylight or when UV isn’t ideal
• Precise tracking through convoluted pipe systems or underground flow paths
• Scalable for both small and large detection jobs
• Safe for controlled release into water systems (when properly diluted, of course)
