15g Luminol Powder Reagent Used in Forensic Investigation - Makes 250mL of Luminol Spray

Used distilled water, works

Does not work. Pricked my finger, got the blood , it showed nothing under the UV light.

Mixed it with distilled water and it worked great. I used it with my daughter who loves science experiments.

The luminol worked exactly as expected. My only complaint was that the spray bottle didn’t actually SPRAY. It kept getting clogged, which forced me to have to transfer it to another spray bottle. Honestly, if this couldn’t have been refrigerated, it would have been a waste.

Verified location of where my pet was shot to death by a neighbor. To avoid frustration, mix in a standard sprayer and apply using mist setting. Included sprayer did not work. Glow only lasted for a short duration, maybe 10 seconds or so. It could be my circumstances but I was applying to an area around 6 days after the incident.

Value

It works as intended

The spray bottle wouldn’t spray. It leaked all over my hands and surfaces that we were trying to spray. I measured and mixed properly but the mixture still did not glow on a spot of blood used as a control to determine if the luminol actually worked. This was a waste of money.
