A blood centrifuge machine is an essential laboratory equipment used that plays a crucial role in separating the serum -buffy coat or plasma from whole blood red cells layers by centrifugation. This process is vital for a variety of tests conducted in blood testing, such as rouleaux detection, agglutination grading, hematocrit and direct antibody identification. Desk top centrifuges with angle rotors are the prefered choice for agglutination grading. By spinning the blood samples with the help of centrifuges fixed heads, the red cells are moved along the side of the test tube at a 45 degree angle. This facilitates easier viewing and examination of the cells.
Blood centrifuges with swinging rotors are used for collection processing and manufacturing. Swinging rotors allow the blood tube or plasma bag to form a flat layer. Centrifuge machines with swing out rotors a larger than serological centrifuges used for ABO RH grading. Larger centrifuge machines are available in bench top or floor standing selections. Floor standing and under benchtop versions are more readily available due to the weight of the equipment. Centrifuges with swing out rotors may hold up to 62 blood collection tubes or 16 processing bags.
Blood collection centrifuges have swing out rotors that initially separate clotted serum or plasma from 2-10ml blood vacutainer tubes. Collection centrifuges often have various rotor insert options that accommodate multiple tube options.
While centrifuges may appear similar in appearance, it is important to note that different models can exhibit varying performance levels, even when set at the same parameters. Moreover, environmental factors like humidity should be taken into consideration during the calibration process. Each centrifuge must be individually calibrated for each specific technique used to ensure optimal spin length. This careful calibration is essential for obtaining proper products and results..
