Really cheap and simple centrifuge for 1,5ml Eppendorf-Tubes. Portable and independent of power supply. Propelled by muscle power.
This centrifuge is suitable to separate blood into serum and hematocrit (10 minutes).
You need just 4 pieces of polystyrene (which match in the reel) and duct tape. Cut holes in the polystyrene to plug in the samples. Please note that the tubes have to be in 45° angels.
