Fluorescein Sodium Salt Powder, 10g For Sale

The powder form of fluorescein sodium salt is a dark orange/red powder that is only moderately soluble in both water and alcohol. When combined with water, it fluoresces as a bright yellow-green. Since the reaction is pH-dependent, the colour can be changed by varying the water’s acidity.

A little bit goes a long way when combining with water. At least 100 litres of water should be coloured using this vial’s contents. At these low amounts, it is organic and safe for the environment.
