Rhodamine 6G – High-Performance Fluorescent Dye for Latent Prints
Our professional Rhodamine 6G (R6G) stands as one of the best fluorescent dyes available for developing latent fingerprints. Forensic laboratories and crime scene investigators use this reagent to enhance prints previously developed with cyanoacrylate (superglue) fuming. Consequently, this dye serves as a vital tool for recovering evidence from non-porous and semi-porous surfaces.
Superior Fluorescence and Versatility
Rhodamine 6G offers an exceptionally high quantum yield. Therefore, it produces brilliant fluorescence under a Forensic Light Source (FLS) or laser. Because a small amount of the dye goes a long way, it remains a highly cost-effective choice for high-volume laboratories.
- Multi-Surface Compatibility: You can use this dye on a wide range of objects, including metal, glass, leather, and plastic.
- Solvent Flexibility: You can dilute the dye in Methanol, similar solvents, or even water. We recommend conducting tests on different surfaces to determine which solvent mixture provides the best results for a particular substrate.
- Highly Sensitive: Even at low concentrations, R6G adheres to the polymerized cyanoacrylate to reveal sharp, clear friction ridge detail.
Professional Application Process
To achieve the best results, you should prepare a working solution by mixing approximately 0.1 gram of Rhodamine 6G in 2–3 litres of solvent.
- Application Methods: You can apply the solution by dipping the evidence, spraying it, or using a wash bottle.
- Visualisation: After the treated evidence dries, examine the prints using an FLS. The dye typically fluoresces between 490nm and 530nm. Use orange or red barrier filters to capture high-contrast photographic evidence.
Safety and Laboratory Standards
Rhodamine 6G is generally safe to use when you follow standard laboratory protocols. Always handle the powder and prepared solutions in a controlled environment using a fume hood. Furthermore, wear appropriate personal protective equipment (PPE) to avoid skin contact or inhalation. We recommend storing the dry powder in a cool, dark place to maintain its chemical integrity for future forensic investigations
