Centrifuge Development Centrifuge is a device for separating samples. It is widely used in biomedicine, petrochemical, agricultural, food hygiene and other fields. It uses the difference in precipitation speed of different substances in the centrifugal force field to realize the analysis and separation of samples. Since the advent of the centrifuge, the progress of low speed, adjustment and overspeed has been mainly reflected in the centrifugal equipment and centrifugal technology, and the two complement each other. From the perspective of rotational speed, the desktop centrifuge is basically in the category of low-speed, high-speed centrifuges. Therefore, it has the technical characteristics of low-speed and high-speed centrifuges. Its structure is mainly composed of motor drive system, refrigeration system, mechanical system, rotor and system control. The composition is only a small size and capacity compared to the floor-standing centrifuge. The development of general-purpose desktop centrifuges has blurred the boundaries of low-speed, high-speed, micro- and large-capacity centrifuges. Numerous rotors provide researchers with a wide range of applications and become the preferred model for research laboratories, such as ST2l in Sorvall, USA. , Germany's Heraeus new model Biofuge Stratos and so on.
