[0028] The inside of the lower end of the glass tube 14 is filled with a macroporous network resin structure layer, and a valve is installed at the bottom;

[0029] The base 10 and the support pillar 11 play a supporting role. The first adjustable bracket 12 can move up and down along the support pillar 11 and is fixed by a locking rod. Moreover, the position of the support rod on the first adjustable bracket 12 is adjustable and is also fixed by a locking rod. One end of the arc-shaped clamping plate 13 is fixed on the support rod, and the distance between the arc-shaped clamping plates 13 is adjusted by the cooperation of a bolt and a spring. The arc-shaped clamping plate 13 is used to clamp the glass tube 14, and the glass tube 14 is used to separate substances.

[0030] Support assembly. The support assembly includes a second adjustable bracket 20, an L-shaped support plate 21, a rotating shaft 23, a connecting ring 27, and a connecting plate 28. One end of the second adjustable bracket 20 is sleeved on the support column 11. One end of the L-shaped support plate 21 is fixed to the other end of the second adjustable bracket 20. One end of the rotating shaft 23 is fixed to the inner side of the L-shaped support plate 21. The connecting ring 27 is sleeved on the rotating shaft 23. The connecting plate 28 is fixed to the side of the connecting ring 27;

[0031] The support assembly further includes a limiting groove 22. The limiting groove 22 is opened on the inner side of the L-shaped support plate 21, and the connecting plate 28 is movably connected to both sides of the limiting groove 22;

[0032] The support assembly further includes a threaded groove 24, a first screw 25, and a limiting plate 26. The threaded groove 24 is opened in the middle of one end of the L-shaped support plate 21. The first screw 25 is screwed into the threaded groove 24. The limiting plate 26 is fixed to one end of the first screw 25 and is movably connected to one end of the rotating shaft 23;

[0033] The second adjustable bracket 20 is the same as the first adjustable bracket 12 and is used to support the connecting plate 28. The L-shaped support plate 21 is used to support the connecting plate 28. The limiting groove 22 plays a limiting role and can keep the connecting plate 28 horizontal. The rotating shaft 23 facilitates adjusting the position of the connecting plate 28 to suit the usage habits of the experimenter. The threaded groove 24 and the first screw 25 play a connecting and adjusting role. The limiting plate 26 plays a limiting role to prevent the connecting ring 27 from falling off the rotating shaft 23. The connecting plate 28 is used to support the hand.

[0034] Working principle:

[0035] Fix the glass tube 14 on the arc-shaped clamping plate 13. Adjust the position of the second adjustable bracket 20. Rotate the connecting plate 28 to drive the connecting ring 27 to rotate around the rotating shaft 23 on the L-shaped support plate 21, so that the connecting plate 28 falls on one side of the limiting groove 22. Rotate the limiting plate 26 to drive the first screw 25 to rotate in the threaded groove 24, so that the limiting plate 26 rotates to the middle of the rotating shaft 23. When in use, the experimenter holds the straw, puts the lower end of the straw into the glass tube 14, and places the hand on the connecting plate 28.

[0036] This step can support the hand and avoid discomfort of the hand caused by dripping the substance to be separated for a long time.

[0037] Please refer to Figures 3 - 4 As shown, based on the above embodiment, this embodiment further includes:

[0038] Adjusting assembly. The adjusting assembly includes a threaded hole 30, a second screw 31, and a support disc 32. The threaded hole 30 is opened in the middle of the connecting plate 28.

[0039] The adjusting assembly further includes a counterbore 33, which is opened in the middle of the support disk 32 and fixed to the second screw rod 31 by screws;

[0040] The threaded hole 30 serves as a connection function, the second screw rod 31 serves as an adjusting function, the support disk 32 serves as a supporting function, and the counterbore 33 is used for connecting screws.

[0041] Working principle:

[0042] Fix the second adjustable bracket 20, rotate the connecting plate 28 so that it is located on one side of the limiting groove 22, insert the second screw rod 31 into the threaded hole 30, and fix the upper and lower support disks 32 with screws through the counterbore 33. During use, as the liquid substance in the glass tube 14 increases, the position where the lower end of the straw is placed will move upward. At this time, one hand can hold the connecting plate 28, and the other hand can rotate the support disk 32 at the lower end of the connecting plate 28 to drive the second screw rod 31 in the threaded hole 30 to rotate, so that the support disk 32 above the connecting plate 28 moves upward. Place the lower end of the straw into the glass tube 14, place the hand on the support disk 32, and slowly drip the substance to be separated into the glass tube 14.

[0043] This step facilitates adjusting the position of the support disk 32 during the separation process and can better support the hand of the experimenter.
