Frequently Asked Questions
In the specialty chemicals sector, Fluorescein is primarily used as a high-sensitivity fluorescence indicator, a REDOX indicator, and a fluorescent tracer for industrial leak detection and hydrological mapping.
Fluorescein is soluble in hot alcohol, acetic acid, and lye, but it is not soluble in water. This makes it ideal for specific organic-based tracers and specialized medical preparations.
Yes, Fluorescein has an excellent safety profile for ophthalmic use at standard concentrations. It is regulatory-approved for identifying corneal abrasions and performing retinal angiography.
Our standard commercial packaging for Fluorescein is 25kg fibre drums, which ensures the powder remains dry and uncontaminated during transit and storage.
It temporarily stains damaged tissue, glowing bright green under cobalt blue light. It causes a harmless temporary yellow discoloration that fades naturally through tears within hours.
This specific wavelength indicates the peak absorption of light at PH 8.0, which defines the dye's efficiency in converting blue light into green fluorescence for high-contrast imaging.
