FAQ:
  • What is luminol used for in criminal investigations?
    Luminol is used to detect bloodstains at crime scenes, even if they have been scrubbed or are old, by reacting with iron in the blood to produce a blue chemiluminescent glow.
  • How does luminol react to produce light?
    Luminol reacts with hydrogen peroxide in an alkaline environment, catalyzed by transition metals like iron, to produce an excited intermediate that emits blue light when returning to the ground state.
  • What are the storage conditions for luminol?
    Luminol should be stored at 0-6°C to maintain its stability and effectiveness.
  • Who manufactures this luminol product?
    This luminol is manufactured by Hubei Xindesheng, a company with years of experience and patented technology in producing high-quality chemiluminescent reagents.
