Forensic Presumptive Blood Test Kit, 30 Tests

This Presumptive Blood Test Kit from Innovating Science demonstrates how forensic scientists use chemistry to test for the presence of blood. Students use phenolphthalein reagent to swab surfaces and observe a rapid color change that indicates blood is present. The test cannot distinguish between human and animal blood. The kit includes 2 bottles of phenolphthalein 2% solution (25mL each), 2 bottles of ethyl alcohol (25mL each), 1 bottle of hydrogen peroxide 3% (50mL), 5 blood standard strips, 50 cotton swabs, a teacher's manual, student study guides, and safety data sheets. Materials for 30 complete tests. For laboratory use only.
