[0027] As Figures 1 - 3 shown, in this embodiment, the support assembly 1 includes a support table 11, a pressure application table 12, and a connecting column 13.

[0028] Among them, the support table 11 is arranged on the balance 24, and the upper end surface of the support table 11 is connected to the pressure application table 12 through the connecting column 13. Exemplarily, the support table 11, the connecting column 13, and the pressure application table 12 are all customized with acrylic plates, and the acrylic plates have good wear resistance and weather resistance and are not easily affected by solvents or other corrosive substances.

[0029] Please continue to refer to Figures 1 - 3 , the pressure application table 12 is provided with a receiving groove 121, and the receiving groove 121 includes a first circular groove 1211 and a second circular groove 1212. Exemplarily, the first circular groove 1211 is arranged above the second circular groove 1212, the diameter of the second circular groove 1212 is smaller than that of the first circular groove 1211, the first circular groove 1211 is used to place the ceramic plate 21, and the second circular groove 1212 is used to receive the liquid flowing out of the separating funnel 23.

[0030] Furthermore, a diversion hole 122 is opened at the center of the bottom of the pressure application table 12, and the pressure application table 12 is connected to the separating funnel 23 through a diversion tube. The diversion tube is U-shaped, and the connection of the glass diversion tube 231 is connected through a rubber tube, so that the pressure application table 12 and the separating funnel 23 form a communicating vessel to ensure the continuous supply of the liquid in the separating funnel 23 to the pressure application table 12.

[0031] As Figures 1 - 3 shown, in this embodiment, the testing assembly 2 includes a ceramic plate 21, a pressure application cylinder 22, a separating funnel 23, and a balance 24. Among them, a filter paper 25 is arranged on the upper end surface of the multi-ceramic plate 21 to filter the liquid flowing out of the separating funnel 23.

[0032] Furthermore, the separating funnel 23 is fixed to one side of the pressure application table 12 through an iron stand 3, and the bottom of the conduit 232 of the separating funnel 23 is higher than or level with the upper end surface of the ceramic plate (21).

[0033] Please continue to refer to Figures 1 - 3 , the pressure application cylinder 22 is placed on the filter paper 25. Among them, the pressure application cylinder 22 is provided with a pressure application groove 221 for placing the sample to be tested.
