LBJ-9/LBJ-900 is a miniature centrifuge device specifically designed for medical and clinical laboratories. It primarily separates red blood cells from plasma using high-speed centrifugation, thereby measuring the percentage of red blood cells in whole blood. This measurement is used to diagnose anemia, polycythemia, or monitor blood health. It is typically equipped with a 24-position capillary rotor, offering rapid and precise operation.
