RAY Reagent Features Formulated for advanced latent print development, the RAY Reagent provides exceptional multi-wavelength fluorescent enhancement. Used extensively by forensic professionals, this specialized dye mixture binds selectively to polymerized cyanoacrylate residues on non-porous surfaces. The compound produces a brilliant fluorescence across a broad spectrum of alternate light sources. Investigators rely on this versatile solution to maximize ridge contrast against difficult, multicolored backgrounds. Engineered for high-throughput crime laboratories, this pre-mixed liquid eliminates the hazards of manually combining multiple raw dye powders. By providing a standardized working strength, technicians ensure court-admissible enhancements with consistent batch-to-batch reliability. When incorporated into standard workflows, the specific carrier solvent promotes controlled application and deep dye penetration. This creates a highly visible, long-lasting print that is easily captured during the photographic phase. To prevent sample degradation, the evidence must be carefully monitored during the staining process to avoid over-development. Maintaining strict control over the rinse phase ensures the background clears while the friction ridges remain deeply stained. For optimal laboratory safety, this chemical wash should always be applied within a certified fume hood. Technicians must utilize appropriate personal protective equipment to prevent solvent exposure. Available Sizes and Configurations SKU Volume Format PF30104-500mL 500 mL Bottle PF30104-1L 1 L Bottle Technical Specifications Specification Detail Product Type Broad-Spectrum Fluorescent Dye Stain Active Components Rhodamine 6G, Ardrox, and Basic Yellow 40 Target Material Cyanoacrylate (superglue) fumed prints Application Phase Post-fuming enhancement Preparation Requirement Ready to use Laboratory Applications For specialized forensic operations, integrating this broad-spectrum dye is critical when processing complex fumed evidence. Crime scene investigators rely on this step when handling items where standard dusting powders offer insufficient contrast. Because it combines Rhodamine 6G, Ardrox, and Basic Yellow 40, the formula is highly valuable for rescuing prints using various excitation wavelengths. Extracting usable intelligence requires a chemical designed for maximum optical flexibility. When processing fumed evidence, the working solution is typically applied via a controlled submersion or delicate wash method. Technicians gently rinse the item with a compatible clearing solvent to remove excess background fluorescence before examining it. Upon achieving the desired ridge contrast, the evidence is immediately photographed using specific barrier filters under an ALS. This critical documentation step ensures maximum AFIS resolution.

This specialized forensic chemical is a fluorescent dye stain utilized to enhance latent fingerprints that have been previously developed using cyanoacrylate (superglue) fuming. It reacts with the polymerized residue, allowing examiners to clearly photograph prints on difficult non-porous surfaces. What makes the RAY formulation unique? RAY is a specialized combination of three distinct fluorescent dyes: Rhodamine 6G, Ardrox, and Basic Yellow 40. This unique mixture allows the developed print to fluoresce across a much broader spectrum of alternate light source (ALS) wavelengths compared to utilizing a single dye, increasing operational flexibility. Does this product need to be diluted? No, this highly specific formulation is provided as a ready-to-use working solution. Crime scene technicians can apply this reagent directly to the fumed evidence without the need for additional complex solvent mixing, saving valuable laboratory processing time.
