3 results about "Continuous flow centrifugation" patented technology

A control system for a centrifuge is disclosed that includes a controller that receives a first pressure signal indicative of a first pressure of a product flowing into or out of the centrifuge and a second pressure signal indicative of a second pressure of a working fluid flowing into or out of the centrifuge. The controller is configured to determine a first pressure differential between the first and second pressures and, in response to the first pressure differential falling below a first predetermined offset, output a first control signal that increases a backpressure of the product flowing out of the centrifuge.

The utility model relates to a kind of continuous flow centrifuge rotor and its baffle structure, by baffle structure, rotor body inner cavity is separated into multiple independent areas, multiple through holes are distributed to each independent area by the liquid to be separated, and the liquid level of each independent area is kept consistent when gap is maintained in liquid inflow. Baffle structure separates rotor body inner cavity, reduces the generation of vortex phenomenon, through hole ensures that liquid is uniformly distributed to each independent area, and gap keeps liquid level consistent during liquid flow, thereby effectively inhibiting vortex phenomenon, ensuring that particles are uniformly settled, and improving separation efficiency.

The application discloses an extracellular vesicle extraction system, application and method for extracting extracellular vesicles, and belongs to the technical field of extracellular vesicle separation. The extracellular vesicle extraction system comprises a raw material storage tank, a deep filtration device, a continuous flow centrifuge, a pretreatment buffer tank, a first filtration device, a concentrated liquid tank, a second filtration device, a product collection tank and a waste liquid tank. The extracellular vesicle extraction system is used for extracting extracellular vesicles, and based on the ultrafiltration and microfiltration technology, the extracellular vesicles in the crushed liquid of Chinese herbal medicines or other plants are separated. Compared with the existing differential centrifugation, density gradient centrifugation, ultrafiltration, immunocapture and other technologies, the process is more suitable for large-batch, standardized and high-efficiency extraction, the product yield is high, the speed is fast, the service life of the filter membrane is greatly prolonged, the process cost is reduced, and the process has great commercial value.
