There is a bead a piece rubber tube, centre, for controlling the flow velocity of solution, and it is molten with non-oxidative for filling alkaline solution
Liquid, all solution that can be worked with rubber tube can not be fitted into base buret, such as KMnO4, K2Cr2O7, iodine solution etc..
Existing buret minimum scale is 0.1mL, and the volume of a drop of liquid is about 0.05ml, in experimentation
It can not accurately measure, error can be caused to experiment, so as to influence end-point analysis；Buret lower end liquid outlet is meticulous, in examination
After testing can not washes clean, easily cause experimental error；Due to acid, the difference of alkali burette material so that in experimentation
Middle needs frequently change acid, alkali burette, are made troubles to operation.
The content of the invention
The purpose of this utility model is the shortcoming for overcoming prior art there is provided a kind of accurate measurement titration pipe device,
Solve existing buret complex operation, measure the technical problem of the difficult cleaning of inaccurate, liquid outlet.
The utility model is achieved through the following technical solutions：
A kind of accurate measurement titration pipe device, including：Buret, fixed support, the buret are placed on institute vertically
Fixed support center is stated, wherein：The buret is by body, capillary cavity, spherical dress liquid device, liquid outlet, disposable screw-casing
Constituted with flow rate adjustment device, the capillary cavity and spherical dress liquid device are provided with the body, the spherical dress liquid device is set
Connected at the middle part of the capillary cavity and with the capillary cavity, the capillary cavity upper end is provided with inlet and exhaust
Mouthful, the bottom of the pipe is connected with the liquid outlet, and the liquid outlet is connected with the capillary cavity, the liquid outlet lower end dress
There is the disposable screw-casing, the liquid outlet is provided with the flow rate adjustment device, and the center line of the capillary cavity is eccentric
Set, its wall unevenness, the tube wall is provided with scale, the scale and the side position pair of thin-walled one of the capillary cavity
Should, the minimum scale value of the scale is 0.01ml.
Further, the capacity of the spherical dress liquid device can be designed as required, and the spherical dress liquid device also can be according to
Need to set up quantity.
Further, the body uses polytetrafluoroethylmaterial material.
The utility model compared with prior art, due to capillary cavity and minimum scale value 0.01ml setting, Neng Gouti
The preci-sion and accuracy of high measurement；Due to capillary cavity be located in body lean on scale side, reduce because refraction and caused by
Error in reading；Due to being provided with disposable screw-casing, replaceable disposable screw-casing after experiment, reduces buret lower end every time
It is meticulous can not washes clean and the experimental error that causes；Because the setting of flow rate adjustment device can accurate coutroi velocity；Due to pipe
Body uses polytetrafluoroethylmaterial material so that without frequently changing acid, alkali burette in experimentation, reduce staff's
Workload；Because spherical dress liquid device can be stored to liquid, it is to avoid capillary cavity internal diameter is too small, amount of liquid storage not enough scarce
Fall into.
The utility model is used for chemical analysis experiment, has the advantages that simple to operate, measurement is accurate, experimental error is small.
