Patent ID: 10258927

Abstract:
The present invention directs to a centrifugal filtration device, for separating living cells, including a spindle (28), a rotary arm (211) which is connected vertically to the spindle (28), a microporous membrane filter (31A;31B) which is mounted on the rotary arm (211), and a liquid distributor (4) arranged above the spindle (28). The microporous membrane filter (31A;31B) includes an inlet (311A;311B), an outlet (312A;312B), a front cavity (313A;313B) having the inlet (311A;311B) formed thereon, a rear cavity having the outlet (312A;312B) formed thereon, and a filter membrane (315A;315B) arranged between the front cavity and the rear cavity; the diameter of each filter pore formed in the filter membrane is smaller than that of the cell which needs to be separated. The present invention also discloses a cell separation system.
