Ardrox is a fluorescent liquid dye which works well with lasers, Forensic Light Sources and UV lamps. Ardrox can be used full-strength or can be diluted with ethanol or methanol, since the solution is about the consistency of syrup, most examiners prefer to dilute it. Ardrox dyes glue-fumed, developed latent prints quite well. While Ardrox-developed prints fluoresce under 365 nm, better results have been reported while examining evidence with 450-480 nm light. Shelf life of unmixed solution: five years, keep in a cool, dry place. Shelf life of mixed solution: one year or longer, store in a fume hood or flammable liquids cabinet. Price shown is per 500ml.
