Fluorescein Sodium in 1% water solution. This format allows a better handling of the fluorescein, since it is practically ready to use as it is already dissolved.<\/p>\n

If you prefer powdered sodium fluorescein, you can find it here: buy fluorescein sodium powder<\/a>.<\/p>\n

\nRelative density (water=1): 0.8-1.0 (estimate based on components).<\/p>\n

1% SODIUM FLUORESCEIN DOSE<\/h2>\n

The dose of fluorescein will vary greatly depending on the application of fluorescein.<\/p>\n

If you want to colour a mass of water, 2 ml of 1% Sodium Fluorescein per litre of water will be sufficient. If you want to detect individual drops and differentiate them from uncoloured water drops, we recommend at least 10ml of the solution per litre of water. The use of a torch or UV light will help you to detect the leak.<\/p>\n

Buy fluorescein sodium diluted to 1%. Fluorescein sodium diluted 1% has a very high concentration, so it must be diluted to be used. As you can see in the picture, 2ml of 1% fluorescein is enough to colour 1L of water. If you wish, you can also buy fluorescein sodium powder<\/a> and make the pre-solution yourself.
