Latent Blood ReagentLuminol Blood Detection SprayFluorescent Latent Blood Reagent, Blood Enhancement Kit for Forensic Investigations, Crime Scene Blood Stain Revealer

Product Description (English Translation) Intended Use For detecting latent bloodstains. Working Principle The main ingredients are luminol and oxidizing agent. Heme in blood catalyzes the oxidation of luminol by the oxidizing agent. Oxidized luminol emits blue light, which can be clearly observed in dark environments. Directions for Use A. Pour 150ml of clean water into a spray bottle. Add 1 tube of Reagent A and 1 tube of Reagent B into the bottle, then shake until fully dissolved. B. In a dark environment, spray the reagent onto the test surface. The appearance of blue fluorescence indicates the possible presence of blood. C. Fluorescence intensity gradually weakens over time and disappears after approximately 30 minutes. Performance Detects bloodstains diluted up to 1:10,000. Identifies bloodstains cleaned with detergents and aged bloodstains. Treated bloodstains do not interfere with DNA analysis. False Positives Stains from fruit juice, soy sauce, and similar substances may also cause the luminol reagent to produce blue fluorescence. Specifications Packaging: Paper box Package Contents: 4 × Reagent A, 4 × Reagent B, 1 × Spray Bottle
