Further clear, complete explanation is made to the utility model.It should be noted that in the case where there is no conflict, in the application
Feature in embodiment and embodiment can be mutually combined.
A kind of acid buret, including the buret 1 with scale value, the bottom of buret 1 are equipped with outlet tube 2, go out liquid
The bottom lock of pipe 2, offers the first liquid outlet 3 on its side wall；Matched outer tube 4, overcoat are arranged with outlet tube 2
The bottom lock of pipe 4, offers the second liquid outlet 5 on its side wall；Positioned at 1 bottom of buret and the top of outer tube 4 on outlet tube 2
Between position be set with compression spring 6, compression spring 6 top be fixed on 1 bottom of buret, outer tube 4 is fixed in bottom
Top；The second liquid outlet 5 on the first liquid outlet 3 and outer tube 4 on outlet tube 2 is located along the same line, in compression spring 6
Under relaxed state, the second liquid outlet on the first liquid outlet 3 and outer tube 4 on outlet tube 2 is in staggered distribution about 5, and goes out liquid
The first liquid outlet 3 on pipe 2 is blocked by the tube wall of outer tube 4.
In use, after pouring standard solution into buret 1, slowly outer tube 4 is pushed up upwards, compression spring 6 is in be compressed
State, when the second liquid outlet 5 on outer tube 4 is slowly overlapped with the first liquid outlet 3 on outlet tube 2, standard solution is from going out
