The cover plate 203 is located on the inner side wall of the bracket 102, and the side wall of the cover plate 203 is fixedly connected to the sliding member 105 by bolts. The filter assembly 200 composed of the filter cartridge 201, the filter element 202 and the cover plate 203 is used to filter the stock solution required for bacterial agent culture. The filter cartridge 201 is fixedly connected to the support plate 107 by bolts, and the upper end of the filter element 202 is clamped in the middle position of the lower end of the cover plate 203. The lower end of the filter element 202 is inserted into the inside of the filter cartridge 201. The cover plate 203 is located on the inner side wall of the bracket 102, and the side wall of the cover plate 203 is fixedly connected to the sliding member 105 by bolts. 01 is installed on the support plate 107, and can rotate with the support plate 107 to shake the raw liquid introduced into the filter cartridge 201, and enter the filter element 202 from the liquid inlet above the cover plate 203, and be filtered by the filter element 202.
