This paper demonstrates that a hand-powered egg beater can be modified to serve as a
centrifuge for separating plasma from human whole blood. Immunoassays used to diagnose
infectious diseases often require plasma from whole blood, and obtaining plasma typically

settings. Human whole blood was loaded into polyethylene (PE) tubing, and the tubing was
attached to the paddle of an egg beater. Spinning the paddle pelleted the blood cells to the …
