A column packing device for a chromatography column with the publication number CN209967746U includes a chromatography column and a column packing device arranged on the chromatography column; the chromatography column and the column packing device are detachably connected; a feed port for adding fillers is arranged on the top of the column packing device, and the column packing device is connected to the chromatography column; the chromatography column includes an inlet, a chromatography column body and an outlet arranged in sequence; the inlet, the chromatography column body and the outlet are connected, and a lower sieve plate is detachably arranged in the chromatography column body near the outlet; the utility model has a simple structure and high efficiency by detachably connecting a column packing device to the chromatography column, which improves the accuracy of filler addition and greatly reduces the equipment cost. In the prior art, the purification column packing is to connect the column packing device, stir the purification filler evenly, quickly pour the filler along the wall of the column packing device, and remove the column packing device after the filler is completely settled in the purification column. However, there is no sealing measure when removing the column packing device, and it is easy to cause waste liquid to spill if you are not careful. It is time-consuming to remove the waste liquid bit by bit. Therefore, the quality of a pre-packed column will directly determine the results of the experiment. Utility Model Content

[0008] The water-stop cover is arranged at the bottom of the liquid storage bottle, and includes a circular ring and two inclined brackets. The upper end of the bracket is connected to the circular ring, and the circular ring is fixedly connected to the rotating shaft. The upper end of the rotating shaft is provided with a ball. The lower end of the bracket is a gasket with a hole, and the lower end of the gasket is connected to the circular cylinder wall. The cylinder wall is provided with a thread to connect with the purifier.

[0009] Preferably, the purifier column loading device is detachably connected to the purifier.

[0010] Preferably, the water stop cover is connected to the purifier by an internal thread.
