The utility model discloses a sour cup is caught up with to two footpaths, including the cup, the cup on be provided with first path cup, the upside of first path cup is provided with big footpath cup, the diameter of big footpath cup is greater than the diameter of first path cup, big footpath cup and first path cup intercommunication.
Further, a second small-diameter cup body is arranged on the upper side of the large-diameter cup body, the diameter of the second small-diameter cup body is smaller than that of the large-diameter cup body, a frosted cup opening is formed in the second small-diameter cup body, and the second small-diameter cup body is communicated with the large-diameter cup body and the first small-diameter cup body.
Furthermore, the volume of the first small-diameter cup body is more than 0mL and less than or equal to 2 mL.
Furthermore, the second small-diameter cup body or the large-diameter cup body is provided with constant volume scale marks.
Further, the second small-diameter cup is coaxially arranged with the large-diameter cup and the first small-diameter cup.
Further, the material of the double-diameter acid-dispelling cup is soluble polytetrafluoroethylene.
Further, the material of the double-diameter acid-dispelling cup is glass.
Compared with the prior art, the utility model, its effect is positive and obvious. The utility model discloses a first path cup is convenient for observe the surplus that catches up with sour solvent, is provided with the constant volume scale mark on the second path cup, conveniently catches up with the constant volume operation after sour operation to use the visual observation method to observe the surplus of solvent, reduced the difficulty of measuring and controlling the solvent surplus.

Detailed Description
Example 1:
as shown in fig. 1 and 2, the utility model discloses a sour cup is caught up with to footpath doubly, including cup 1, cup 1 on be provided with first path cup 3, the upside of first path cup 3 is provided with big footpath cup 4, the diameter of big footpath cup 4 is greater than the diameter of first path cup 3, big footpath cup 4 and first path cup 3 intercommunication.
Further, a second small-diameter cup body 5 is arranged on the upper side of the large-diameter cup body 4, the diameter of the second small-diameter cup body 5 is smaller than that of the large-diameter cup body 4, a frosted cup opening 7 is formed in the second small-diameter cup body 5, and the second small-diameter cup body 5 is communicated with the large-diameter cup body 4 and the first small-diameter cup body 3.
Specifically, a sanding plug is arranged in the sanding cup opening 7, and the sanding plug is matched with the sanding cup opening 7.
Further, the volume of the first small-diameter cup 3 is greater than 0mL and less than or equal to 2 mL.
Furthermore, the second small-diameter cup body 5 or the large-diameter cup body 4 is provided with constant volume scale lines 6.
Further, the second small-diameter cup 5 is disposed coaxially with the large-diameter cup 4 and the first small-diameter cup 3.
Further, the material of the double-diameter acid-dispelling cup is soluble polytetrafluoroethylene.
Further, the material of the double-diameter acid-dispelling cup is glass.
Specifically, the first small-diameter cup 3 satisfies the formula, wherein D2Is the diameter of the first small-diameter cup body 3, h is the vertical height of the first small-diameter cup body 3, and the second small-diameter cup body 5 and the constant volume scale mark 6 are used for constant volume operation after acid removal is finished.
