The pipette can be inserted into the jacks 121 on the first limiting plate 11 and the second limiting plate, and the lower end of the pipette is in the supporting holes 131, so as to place the pipette.
[0033] Furthermore, the blowing member 2 also includes a fixed plate 21, and several blowing nozzles 23 are fixed on the fixed plate 21. Branch pipes 24 are provided on the input ends of the several blowing nozzles 23, and the several branch pipes 24 are connected to the bottom of the rotating rod 15. The blowing member 2 can be used to blow air on the cleaned pipette on the frame 1, thereby accelerating the flow of moisture on the surface of the pipette, so that the pipette can be dried quickly.
[0034] Furthermore, 1, the lower end of the rotating rod 15 passes through the bottom plate 14 and is rotatably connected to the bottom plate 14. The rotating rod 15 is rotatably arranged on the bottom plate 14. By rotating the rotating rod 15, the limiting plate 11 and the limiting plate 2 12 can be driven to rotate together, which makes it easier for users to place the pipette.
[0035] It should be noted that the lower end of the rotating rod 15 is connected to a main pipe 25, and the rotating rod 15 is connected to the purification instrument air duct of the experimental bench through the main pipe 25.

[0040] When the pipette is inserted into the pipette rack, the pipette passes through the through hole on the limiting plate 3. When the pipette perforates the limiting plate 3, the inner limiting end 32 of the limiting plate 3 will bend downward. The bent limiting end 32 can rest against the outer surface of the pipette, so that the pipette can stand vertically more stably, avoiding the pipette from tilting easily so that the nozzle 23 cannot be aligned with the washing hole at the lower end of the pipette.
