Description
Basic Yellow 40 Fluorescent Dye 1-litre – Latent Print Enhancement
Our professional Basic Yellow 40 Fluorescent Dye 1-litre (BY40) provides a highly effective solution for enhancing latent fingerprints. Forensic technicians specifically use this dye to process non-fluorescent, multi-coloured surfaces. Consequently, this reagent serves as a vital tool for crime scene investigators who need to visualise prints on complex backgrounds.
Superior Visualisation on Complex Surfaces
Investigators typically use Basic Yellow 40 after the cyanoacrylate (superglue) fuming process. While superglue fuming creates a stable white deposit, these prints often lack contrast on patterned or light-coloured items. Therefore, applying this fluorescent dye ensures the ridge detail stands out clearly against the substrate.
- Targeted Fluorescence: Once applied, the developed prints will fluoresce a bright yellow/green colour.
- Light Source Compatibility: You can easily view these enhanced prints using a forensic light source or UV light. The dye reacts optimally between wavelengths of 365nm and 485nm.
- Enhanced Contrast: This process allows you to capture high-resolution photographic evidence of fingerprints that were previously invisible or poorly defined.
Versatile Application and Safety
We supply this dye in a convenient 1-litre volume to support high-volume laboratory requirements. You can apply Basic Yellow 40 by dipping, spraying, or using a wash bottle, depending on the size of the evidence. Because this formulation adheres specifically to the polymerized cyanoacrylate, it leaves the background clear and provides a sharp, detailed image of the ridge patterns.
Professional Forensic Standards
Basic Yellow 40 is a cornerstone of modern forensic chemistry. It offers a reliable and repeatable method for evidence processing. However, you should always handle this chemical in a controlled laboratory environment. Use a fume hood and wear appropriate personal protective equipment (PPE) during the application process. Furthermore, ensure you store the solution in a cool, dry place to maintain its fluorescent properties.
