Laboratory centrifuges, or experimental centrifuges, are small centrifuges that are professionally used for experimental analysis. A centrifuge is an instrument that simulates the earth’s gravitational field by centrifugal force on an object rotating around a fixed axis of rotation, causing the object to perform a sedimentation motion, thereby separating fractions of different densities and molecules in the substance. The technology of analyzing and separating substances by centrifugal sedimentation is called centrifugal technology. At present, various centrifuges and centrifugal technologies have been widely used in scientific research and production departments, and have become one of the important instruments and equipment of modern scientific research. Laboratory centrifuges are necessary equipment for scientific research and production in biology, medicine, agronomy, bioengineering, biopharmaceutical and other industries.
