Safely Study Blood Typing
Using four different samples of simulated blood, your child will determine each unknown sample’s blood type and Rh factor, examine the risk of Rh incompatibilities, and even view red and white "blood cells" under a microscope in complete safety.
The Simulated Blood is entirely non- biological, so there are no worries of blood-born pathogens. This non-toxic simulated blood is so safe and easy to dispose of, you can pour it right down your kitchen sink. Pack includes four simulated blood types, three anti-sera (A, B and Rh), typing tray and instruction guide.
