Bright Dyes® FLT Yellow/Green Wax (Cake)

1 of 16 products in this brand
Bright Dyes® FLT Yellow/Green Wax (Cake) is specially formulated versions of Xanthene dye, certified by NSF International to ANSI/NSF Standard 60 for use in drinking water. This dye is the traditional fluorescent water tracing and leak detection material and has been used for labeling studies from the beginning of the century. It may be detected visually, by UV light and by appropriate fluoremetric equipment. Today it is most often used visually. This dye has been used by the military to mark downed pilots for search and rescue operations over large water bodies. Visually the dye appears yellow/green, depending on its concentration and under UV light as lime green. It is best for visual inspections of moderate volumes of water, 20,000-50,000 gallons.

Product Highlights

It is based on biochemical oxygen demand (BOD) studies, the dye is biodegradable with 65% of the available oxygen consumed in 7 days. The dye is resistant to absorption on most suspended matter in fresh and salt water. However, compared to Bright Dyes FWT Red products it is significantly less resistant to degradation by sunlight and when used in fluoremetry, stands out much less clearly against background fluorescence. As always a qualified hydrologist or other industry professional should evaluate the use and suitability of these products for any specific application.

Features
  • FLT Yellow/Green vibrant color offers greater contrast in murky brown water
  • It’s fluorescent properties offers greater apparent contrast than non-fluorescent blue
  • May be used for visual, ultraviolet and fluorometric inspections
  • Disappears in sunlight more rapidly than FWT Red dye and non-fluorescent blue
