Basic fluorescein with 98.5 % purity, for use in chemistry, biology and environmental labs as a fluorescent tracer and analytical dye.
Solid fluorescent dye for preparing reference solutions for spectrofluorimetry, diffusion studies and educational demonstrations of fluorescence.
Available in 25 g, 50 g and 100 g packs, suitable for analytical platforms, R&D labs and higher‑education teaching without excessive dye stock.
This 98.5 % pure basic fluorescein is an anionic fluorescent dye widely used as a tracer in hydrology, environmental engineering and process studies, as well as a fluorescence standard for spectrofluorimeter calibration. Its strong fluorescence and controlled purity make it suitable for quantitative measurements and educational demonstrations. The different empirical formulas given reflect possible hydrated or salted forms; the exact specification should be checked in the SDS or product certificate. As a combustible organic solid, fluorescein must be handled so as to minimise dust generation and stored away from ignition sources. Users must follow the safety data sheet and comply with French and EU regulations on storage and hazardous‑waste disposal.
