Using a salad spinner to diagnose anemia

Yet another cool low-tech invention in the healthcare space from Rice U., literally in walking distance from where I live: a salad-spinner that's been retrofitted to be a centrifuge that splits blood into plasma and blood cells. It's purpose is to help diagnose anemia in the field among people who live in poor, remote regions of the world. And without electricity, just a bit of muscle power.

The device is called the Sally Centrifuge and you can read about it here and, with more details and a reference to the other cool health-related invention from Rice U. I witnessed last year at a business plan contest, here. (That contest by the way was hosted by the real incubator of these and other low-tech devices, Beyond Traditional Borders.)

Here's a video with a short demonstration of the "centrifuge" and the two inventors. I'm not sure how the resulting separated blood will be interpreted, but I'm curious enough to find out.

From what I understand, it takes about 5 minutes of spinning at 10,000 RPM to get the separation right. I hope the inventors have taken this into account, and that the spinning doesn't tire the user out.
