Kastle-Meyer Reagent, 100 mL, Forensic Test

Item #: AP7555

Price: $10.60

Classic test for the presence of blood at a crime scene! Kastle-Meyer reagent contains reduced phenolphthalein indicator in a basic solution. Simply wipe a presumptive bloodstain with a cotton swab, add a drop of the reagent, and then apply a drop of hydrogen perozide. If the swab turns pink rapidly, it is positive for blood! For a terrific guided-inquiry forensic activity, use the Kastle-Meyer reagent to investigate substances that will interfere with the test to give false positives.
