Description
Amido Black (Naphthalene Black) – 25g Blood Protein Dye
Our professional Amido Black (Naphthalene Black) provides a highly sensitive protein dye for enhancing latent fingerprints and footwear impressions made in blood. Forensic investigators and laboratory technicians use this reagent to process both porous and non-porous surfaces. Because the dye reacts specifically with blood proteins, it reveals critical ridge detail and tread patterns that are otherwise invisible to the naked eye.
Advanced Blood Pattern Enhancement
You can use Amido Black to develop high-contrast images on various substrates, including cadavers, wood, and paper. Consequently, it serves as a vital tool for major crime scene investigations where blood contamination is present.
- Superior Sensitivity: This dye identifies trace amounts of blood even after attempts to clean a surface.
- Versatile Substrates: It works effectively on smooth metals, plastics, and even complex porous materials.
- Professional Visualisation: The reaction produces a deep blue-black stain. Therefore, you can capture high-resolution photographic evidence with excellent clarity against light-coloured backgrounds.
Expert Formulation and Mixing
We supply Amido Black in a 25-gram high-purity powder format. Depending on your environment, you can prepare several different working solutions.
- Methanol-Based Solution: You can mix the powder with Glacial Acetic Acid and Methanol. While highly effective, this version is best suited for controlled laboratory settings.
- Water/Ethanol/Acetic Acid Formula: The UK Centre for Applied Science and Technology (CAST/DSTL) recommends this safer formulation. It stains just as effectively as methanol-based versions.
- Crime Scene Application: For processing large areas like shoeprints in blood at a scene, we advise using water-based staining solutions to reduce volatility and improve safety.
Safety and Laboratory Handling
Because Amido Black is a concentrated protein stain, you must handle it with extreme care. Always prepare and apply the solution in a well-ventilated area or under a fume hood. Furthermore, wear appropriate personal protective equipment (PPE) to avoid staining your skin or clothing. Store the dry powder in a cool, dark place to maintain its chemical integrity.
