Lufast latent bloodstain reagent

Lufast is a newly developed, high-sensitivity chemiluminescent reagent specifically designed for the detection of latent blood.
Upon contact with latent blood, it immediately emits a high-brightness, persistent green light that is visible to the naked eye and is not affected by the color of the substrate, especially for trace amounts of latent blood on dark surfaces. It can be used for rapid search and localization of latent blood at crime scenes involving homicide, assault, and other major criminal cases.

Advantages of Lufast Compared to Traditional Luminol-based Reagents on the Market:

  •  High luminous brightness, lasting longer than traditional luminol.
  •  High sensitivity, capable of clearly revealing blood diluted more than 1/100,000 times.
  • Stable reagent that does not need to be prepared for immediate use and has a shelf life of over 18 months at room temperature.

Product Features:

  • Emits a bright green light, no need for a completely dark environment.
  • Long-lasting luminescence, convenient for photographic documentation.
  • High sensitivity, capable of revealing blood diluted over 1/100,000 times.
  • It can be used directly by spraying, making operation convenient.
  • Stable quality, can be stored for 5 days after mixing.
  • Water-based solvent, safe to use.
  • Does not destroy DNA.
Product Parameters:
  1. For rapid search and discovery of unknown bloodstains.
  2. Solution formula, ready-to-use by direct spraying, one-step operation without the need for preparation or dissolution.
