This invention discloses a compact
protein purification device, relating to the field of
protein purification equipment technology. It includes a ring frame, a support column mounted below the ring frame, and a base connected to the support column; a moving mechanism mounted on the base, the moving mechanism including a third lifting rod mounted on the base, a rotating ring rotatably connected to the outside of the support column, and a disc connected to the rotating ring via an adjusting member. The third lifting rod drives the rotating ring, the adjusting member, and the disc to move vertically. It also includes a mixing cylinder and a
processing mechanism mounted on the ring frame; a second annular groove formed inside the ring frame; a support frame slidably connected to the support column; a receiving cylinder located below the mixing cylinder; and a gravity
chromatography column connected to the receiving cylinder via a connecting
pipe. This compact
protein purification device, by incorporating the
processing mechanism and the moving mechanism, achieves the goal of improving the efficiency of the equipment.
