Description

Luminol Powder 99% is a high-purity chemiluminescent compound renowned for its ability to emit a bright blue glow when oxidized. Commonly used in forensic science, this high-grade luminol is also ideal for laboratory experiments, educational demonstrations, and biochemical research. Its stable and reliable glow under specific conditions makes it a valuable tool for detecting trace amounts of blood and other biological substances.

Applications:

  • Forensic Science:
    • Used in crime scene investigations to detect trace amounts of blood. Luminol emits a blue glow upon reaction with iron in hemoglobin, helping forensic teams identify blood splatter and trace evidence.
  • Educational Demonstrations:
    • Popular in schools and universities for demonstrating chemiluminescence. It’s a great visual tool to showcase chemical reactions that produce light without heat, sparking interest in chemistry and forensic science.
  • Biochemical Research:
    • In enzyme-linked chemiluminescent assays, luminol helps detect and measure peroxidase activity in biological samples. This is useful for identifying specific enzymes or biomarkers in biochemical research and diagnostics.
  • Analytical Chemistry:
    • Applied in analytical chemistry for various detection assays, especially in research labs where sensitive and selective chemiluminescent detection methods are needed.
  • Environmental Testing:
    • Used in testing for trace metals and certain chemicals in water samples. Luminol reacts with oxidizing agents, allowing scientists to identify contaminants and pollutants in environmental analysis.
  • Medical Diagnostics:
    • Integrated into diagnostic tools and assays that use chemiluminescence to detect antibodies, enzymes, and other biomolecules in clinical settings, helping with disease diagnosis and monitoring.
  • Cosmetics and Skincare Testing:
    • Employed in oxidative stress research, including in skincare, to study the presence and impact of reactive oxygen species (ROS) on skin cells.

Storage and Handling:

  • Storage Conditions: Store in a cool, dry, and well-ventilated area, away from direct sunlight and heat sources.
  • Packaging: Provided in air-tight containers to preserve stability and prevent moisture absorption.
  • Personal Protection: Use appropriate PPE such as gloves, safety goggles, and lab coats when handling.
