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

Used distilled water, works

Value

This was a complete waste of money. It was purchased for a demonstration with our department’s citizen academy. The instructions were followed to the letter. The bottle would not seal. The nozzle worked more like a squirt gun, never producing anything that resembles a mist. Don’t wast your money. We are very disappointed!

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.

It works as intended

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.

Used it to teach part of a forensic scince class at my high school

Luminol can be used to detect some blood traces and other physiological fluids. Also, you can see the glow without an uv lamp, so is highly recommended during simple class demonstrations, even in school's science fairs
