30ml Pure Fluorescein Solution - Fluorescent Dye

Fluorescein is a synthetic organic compound used as a dye and fluorescent tracer, commonly employed in medical diagnostics, particularly in ophthalmology to highlight parts of the eye during procedures. It appears as a dark orange/red powder and produces a yellow green color in aqueous solutions.

Uses of Fluorescein

Ophthalmology: Fluorescein sodium is widely used in eye examinations. It helps visualize parts of the eye, such as the retina and iris, during procedures like fluorescein angiography. It can diagnose conditions like corneal abrasions and ulcers.

Eye Staining: Fluorescein eye stain tests detect foreign bodies and corneal damage using a blue light.

Other Applications

Dye Tracing: Used in various fields, including forensics and environmental studies, to trace water flow and detect leaks.

Microscopy: Acts as a fluorophore in biological imaging and research.

Safety and Side Effects

Fluorescein can cause adverse reactions, particularly with intravenous use. Reported side effects include nausea, vomiting, and in rare cases, anaphylaxis. The incidence of these reactions varies, with rates between 1% to 6%.
