Overview:

The rotor is also the core component of centrifugation technology. It is used in conjunction with a centrifuge to separate samples, and aside from the centrifuge itself, the rotor is an indispensable part of the process. To achieve optimal separation results, selecting the right rotor is crucial. The purity of the separated samples, as well as the duration of the separation process, are closely related to the type of rotor used. Our company manufactures a variety of rotors, including fixed-angle rotors, horizontal rotors, continuous-flow rotors, horizontal ELISA rotors, and horizontal swinging-bucket rotors.

Throughout the entire field of systems biology, centrifugation technology is “ubiquitous.” Whether working with nucleic acids, proteins, or cells, ultracentrifuges are used as a key tool for separation. Moreover, as an analytical technique, ultracentrifuges can help determine protein structures, elucidate interactions between proteins or between proteins and small molecules, and measure molecular weights, among other applications. They also enable scientists to delve deeper into various levels of protein function, examining how proteins interact under different biological conditions and in specific contexts. This, in turn, enhances our understanding of life itself, sheds light on the mechanisms underlying disease development and progression, and provides a more precise information base and technological platform for the development of new drugs.

　The ultracentrifuge is an indispensable technical tool in biochemistry and molecular biology. It is widely used for the separation and purification of macromolecules, cells, organelles, and other cellular components. By means of centrifugal separation or centrifugal analysis, it is sometimes possible to directly obtain information about cells, organelles, viruses, and biological macromolecules; in other cases, it provides a foundation for further chemical analysis, determination of biological functions, and morphological observation of ultrastructural features. Depending on the specific objectives, different methods and techniques can be employed. After ultracentrifugation, a solution typically separates into a supernatant and a pellet. However, both the pellet and the supernatant are heterogeneous: the former contains all the particles originally present in the solution, while the latter still contains a small number of particles, though these particles are much smaller than those in the pellet. The supernatant obtained in this way can then be subjected to further centrifugation at even higher speeds to separate its components—a process known as differential centrifugation. If highly pure substances are required, analytical ultracentrifugation should be used instead. Density-based ultracentrifugation allows one to determine certain physical properties of substances, such as their sedimentation coefficients and approximate densities, and also yields a relatively pure sample of the substance in question.
