Blood ID Leuco-Malachite Reagent Kit

This Blood Identification Kit utilizes Leuco-Malachite (McPhail's Reagent) to provide a field test for the presumptive identification of blood. Each test consists of two chemical reagent ampoules contained in a rugged disposable pouch. A blue/green color reaction indicates the presumptive presence of blood (a positive reaction can occur in as little as one part per million). Includes 10 tests, filter paper and distilled water.
