centrifuge usage in clinical laboratory

Author: Date:2010-03-21

    Using a centrifuge in the clinical laboratory techniques for the separation of liquid and solid components is essential.

 

    On Biochemical analysis of body fluids in the laboratory,a centrifuge is used for separating blood cells conventionally serum / plasma, and also be used for separating the precipitate from the urine, to measure the blood (hematocrit), the volume fraction of red blood cells, and independent of the free component binding protein binding and immunoprocedures. Less typically, be used in centrifugal separation of lipoproteins for the separation of the reference program their measurement, the cell component is separated and the DNA fragment.

 

    In today's clinical chemistry laboratory, high capacity horizontal head or swinging bucket units, wherein the specimen tubes are spun at a 90 ?? angle to the shaft of the rotor, are the most common centrifuges. These devices centrifuge the vast majority of tubes at a speed of 3500 rpm for 10 minutes. In addition, temperature-controlled centrifuges-horizontal head or swinging bucket centrifuges that maintain a temperature of 4 ?? C-are used to preserve the integrity of thermolabile analytes, which can be adversely affected by the heat generated by most devices during the centrifugation process.
