Sirchie Luminol Reagent with Spray Head, 8oz, 2 Pack

The Sirchie Luminol (8oz, 2 Pack) is a chemiluminescent substance that can be used as a presumptive test for the presence of blood. Making use of the peroxidase-like 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 essential. 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.
