Ultrafiltration tube structure for exosome extraction

The utility model relates to the technical field of exosome extraction, in particular to an ultrafiltration tube structure for exosome extraction, which comprises an ultrafiltration tube body, the ultrafiltration tube body can be applied to a centrifugal machine and comprises a centrifugal tube, a filter structure for filtering liquid is arranged in the centrifugal tube, and the filter structure is arranged in the centrifugal tube. A filtering structure for filtering exosomes is arranged in the centrifugal tube; the filtering structure comprises a filtering membrane and an ultrafiltration membrane assembly, the filtering membrane is used for intercepting large-particle molecules in the urine sample, and the ultrafiltration membrane assembly is used for intercepting small-particle molecules in the urine sample. Compared with the prior art, the ultra-filtration tube structure for exosome extraction is relatively simple in structural design and convenient for manufacturers to produce, so that the delivery cycle
