Integrated lymphocyte separation tube

The utility model relates to the technical field of cell separation devices, in particular to an integrated lymphocyte separation tube which comprises a centrifugal tube, a first annular groove is formed in the top of the inner wall of the centrifugal tube, a built-in sleeve is movably connected into the centrifugal tube, a limiting ring is arranged at the top of the outer wall of the built-in sleeve, and a centrifugal bin is arranged at the bottom of the built-in sleeve. A centrifugal hole is formed in the bottom end of the centrifugal bin; a tube cover is in threaded connection with the top of the outer wall of the centrifugal tube. According to the integrated lymphocyte separation tube, the built-in sleeve can be taken out from the centrifugal tube, so that a worker can pour out erythrocytes in the centrifugal tube, later waste treatment is facilitated, and the environmental protection risk is avoided; the limiting ring of the built-in sleeve is movably inserted into the first annular groove of the centrif
