Specific embodiment
It is illustrated below in conjunction with preferred embodiment of the attached drawing to the utility model, it should be understood that described herein excellent
It selects embodiment to be only used for describing and explaining the present invention, is not used to limit the utility model.
Embodiment 1
As shown in Figs. 1-2, a kind of quartzy buret, including liquid inlet 1, titration tube body 3, connecting tube 5, resistant material
Layer 9 and first compound tube 10, liquid inlet 1 are mounted on the top of titration tube body 3, titration tube body 3 by the first compound tube 10 with
The combination of second compound tube 12 composition, the first compound tube 10 and the second compound tube 12 expands the storage capacity of titration solution significantly, the
The bottom of two compound tubes 12 is equipped with connecting tube 5, and control valve 6 is equipped on the side outer wall of connecting tube 5, and connecting tube 5 passes through rubber
Gum cover 7 is equipped with liquid outlet 8, and etch resistant material layer 9 is arranged on the inner wall of titration tube body 3, what etch resistant material layer 9 used
It is made of polyurethane material component, control valve 6 is made of installation shell 14, rotary shaft 15 and block 16, and control valve 6 can
The flow of solution is controlled, people can also press the flow that rubber sleeve 7 removes control liquid by hand, to substantially increase titration work
The precision of work titrates and is provided with graduated scale 4, the side of the first compound tube 10 and the second compound tube 12 on the outer wall of tube body 3
Fixing sucking disk 2 is mounted on outer wall, which can directly be adsorbed on metope by fixing sucking disk 2, without passing through fixation
