According to the speed classification, centrifuges can generally be divided into the following types:
Ordinary centrifuge (low speed) <8000r/min;
High speed centrifuge 8000 ~ 30000r / rain;
Ultracentrifuge 30000 ~ 80000r / min;
Ultra high speed centrifuge >80000r/min.
Under normal circumstances, the medical centrifuge is a low-speed centrifuge, the speed is generally not more than 5000r / min, the horizontal rotor can be used, and can meet the needs of large capacity. For laboratory, scientific research units and other laboratory centrifuges, high-speed centrifuges (greater than 5000r/min) are generally required, and small-capacity angular rotors are used.
When selecting a centrifuge, the laboratory can select centrifuges with different capacities, different speeds and different temperature control according to the purpose of the experiment and the needs of the experiment.
