An electrically-powered device intended to be used in a clinical laboratory setting for the centrifugation of gel column agglutination cards used to perform manual blood typing assays. It is a dedicated compact benchtop unit with an electric motor, a shaft, a rotor with slots specifically shaped for use with gel column cards, and speed and time controls. The device is intended to centrifuge gel column agglutination cards for the manual determination of antigens of multiple blood systems (e.g., ABO, Rh, Kell) for compatibility testing and detection of unexpected antibodies.
