Sirchie LUMINOL4 Luminol Invisible Blood Reagent w/ Spray Head (2 x 4 oz Bottles)

Luminol is a chemiluminescent substance that can be used as a presumptive test for the presence of blood. Making use of the peroxidaselike activity of the heme portion of hemoglobin,Luminol produces a bluish-white light that can be viewed in total darkness. Invisible blood stains react with the Luminol reagent by luminescing—darkness is crucial. It can also be photographed or videotaped with the aid of the SIRCHIE KRIMESITE IMAGER. A very useful test for searching large areas for blood especially if the area has been cleaned up.
