Neo/Blood looks and behaves like real blood, giving you and your class quick, easy, and completely safe results. This revolutionary substance realistically simulates agglutination. It even contains simulated, microscopic blood cells—of the same size and concentration as in actual human blood. These cells can be viewed and counted under a microscope or used with a hemacytometer to obtain actual blood cell counts and percent solid determinations. Neo/Blood's amazing results can be used for a variety of teaching applications, from basic blood typing to the genetics of blood—even forensic scenarios. Each Neo/Blood investigation is based upon interesting, "real-world" scenarios and comes with enough materials to accommodate 40 students.
