Bright Dyes® FLT Blue Tablet

1 of 16 products in this brand
Bright Dyes® FLT Blue Tablet is specially formulated versions of food grade dye FD & C Blue. Bright Dyes® FLT Blue products have been certified by NSF International to the ANSI/NSF Standard 60 for use in drinking water. This dye is used for visual detection only and cannot be seen under ultraviolet light or detected by fluorometry. However, when used visually, its color is often thought to be more acceptable to public view than the fluorescing red or yellow green Bright Dyes® products. In this respect, it is sometimes used in fountains, ponds and streams for decorative effect. Visually, the dye appears as aqua to royal blue depending on its concentration and activity of the water.
