Scientists turn toy into a 20-cent blood centrifuge

The poorer regions of the world are also hotbeds of diseases like malaria, tuberculosis, HIV, and sleeping sickness. To combat these scourges, doctors use centrifuges to process blood samples. Spinning at thousands to hundreds of thousands of RPMs, the bench-top lab machines generate thousands of G’s that cause the various components in blood to separate out into layers like cream from milk in a cream separator. Combined with chemical dyes and microscopes, they are a powerful weapon in combating disease by helping to isolate and identify microbes for diagnosis.
