CROSS-REFERENCE TO RELATED APPLICATIONS AND PRIORITY
[0001] The present application claims no priority from any of the patent application(s).
FIELD OF INVENTION
[0002] The present invention relates to the field of a centrifuge system. More particularly, the present invention relates to a rotor-bucket assembly of the centrifuge system.
BACKGROUND OF THE INVENTION
[0003] This section is intended to introduce the reader to various aspects of art, which may be related to various aspects of the present disclosure that are described or claimed below. This discussion is believed to be helpful in providing the reader with background information to facilitate a better understanding of the various aspects of the present disclosure. Accordingly, it should be understood that these statements in this background section are to be read in this light, and not as admissions of prior art. Similarly, a problem mentioned in the background section or associated with the subject matter of the background section should not be assumed to have been previously recognized in the prior art. The subject matter in the background section merely represents different approaches, which in and of themselves may also correspond to implementations of the claimed technology.
[0004] Centrifuge systems are widely used for conducting centrifugation process to separate components of a mixture based on their density. Such systems typically include a rotor body and buckets where the mixture is placed. Further, the rotor is configured to rotate at high-speed to generate centrifugal force. Furthermore, the centrifugal force leads to separation of mixture, so the centrifugation of samples within the buckets is achieved. The centrifuge systems are commonly used in healthcare utilities, research and development centres, pharma industries, and test laboratories. There are various types of conventional centrifuge systems are available in market such as microcentrifuges, benchtop centrifuges, high-speed centrifuges, ultracentrifuges, decanter centrifuges, disc stack centrifuges, tubular bowl centrifuges, gas centrifuges, continuous flow centrifuges, analytical centrifuges, and many other.
[0005] In the conventional centrifuge system, the rotor has a problem of inferior balancing. Basically, balancing is a crucial concern for centrifuge systems, especially at high rotational speeds. However, imbalance can lead to excessive vibrations, causing mechanical wear, and potential damage to the rotor and other components. Further, such problem may also pose safety risks and lack of operational efficiency. In conventional solutions, such issues are prevented by use of counterweights and maintaining symmetricity. However, such existing solutions are not capable enough to completely minimize the imbalance factor. In some conventional centrifuge systems, automatic balancing, and imbalance detection systems are incorporated. However, these systems also fail to mitigate the poor stress distribution at various parts of rotor such as arm, neck, and pin.
[0006] The buckets used in the conventional centrifuge systems experiences an aerodynamic drag while rotating at high speed. Such aerodynamic drag on buckets outer surface can oppose the overall speed of the rotor. Additionally, such air resistance can create additional forces that affects performance and stability. Further, this drag can cause vibrations and damage the centrifuge or samples. In some scenarios, the aerodynamic drag also causes wear and tear to the bucket body. In conventional solutions, the internal chamber of the buckets is maintained under vacuum to minimize aerodynamic drag. However, these solutions are not enough to mitigate the effects of aerodynamic drag. Also, there is no other solution is established for ensuring resistance to aerodynamic drag acting on the outer surfaces of the one or more bucket.
[0007] The conventional centrifuge systems use heavier rotor-bucket combination. The heavy weight of rotor-bucket combination affects the consistency of rotational speed of the rotor. Thus, the conventional rotors and buckets experiences to lack of efficiency in the process of centrifugation. Also, the heavy weight of the rotor-bucket combination induces additional wear and tear to the associate components such as bearings and fasteners. Therefore, such conventional heavy weight rotors increase overall cost in manufacturing, maintenance, and repair of the centrifuge system. In addition to the above heavy weight problem, the conventional rotor-bucket combinations of centrifuge system leads to excessive time and energy consumption for the centrifugation process. Therefore, the existing solutions fails to meet the industry requirements from the point of efficiency in centrifugation process.
[0008] In light of the above stated discussion, there exists a need of a centrifuge system with an improved rotor and bucket combination to overcome at least one of the above stated problems.

[0027] In general, a centrifuge system is a device that uses centrifugal force to separate components of a mixture based on their density. Basically, the centrifugation systems include a rotor and a container combination. Further, the system performs centrifugation by spinning a sample within the container at high speeds.
