Chemiluminescence in Bloodstain Detection


Innovating Science™.

Crime scene investigators are called to the scene of a possible violent crime.They examine the scene for evidence, such as fingerprints, hair, fibers, etc. After collecting the evidence, they notice there is no visible blood. Someone takes out a spray bottle and begins to spray the area with a liquid. After the area is covered with spray, they turn out the lights. A strange, faint glow appears in certain areas of the scene.

Learn how luminol is used in scenes like this everyday.The special Luminol formulation does not require a separate hydrogen peroxide catalyst. Simply re-hydrate and use with the simulated blood hemoglobin to show your class.This activity includes an Instruction Manual with suggested activities.There is enough material for several demonstrations.

Materials included are:
2 bottles luminol reagent powder
1 bottle simulated blood hemoglobin
