Description
Technical field
It the utility model is related to a kind of new acid buret of titrimetry.
Background technology
Buret is measuring device most basic in titrimetry.Different according to the device of control solution flow rate, buret can divide
For two kinds of acid and alkali formula.The lower end of acid buret is equipped with glass piston, for holding acidity or having oxidizing solution.Alkali
The lower end of formula buret connects a cuvette with emulsion tube, has a bead in emulsion tube, to control the outflow of solution.
Alkali formula pipe is used for filling alkaline solution and non-oxidative solution.
Need to apply vaseline on glass piston during acid buret use, the easy stuck or seepage of glass piston, and
The difficult discharge of bubble, inconvenient for use at its sharp mouth.
The content of the invention
In order to solve one of defect present in above-mentioned prior art, there is provided a kind of new acid buret.
Technical scheme is used by the utility model solves its technical problem：
A kind of sharp mouth below new acid buret, including body and body, the body are integrally formed company with Jian Zui
An entirety is connected in, the body upper end is provided with cock body, and being passed through in the cock body has hard tube, and the end of hard tube is connected with knob；
Also include an obturating plug, the obturating plug is provided with the groove being engaged with the sharp mouth.
The sharp mouth of body and lower section is connected as an entirety by new acid buret of the present utility model, without sebific duct or
Glass cock controls dropping liquid, and is controlled using the knob on hard tube, easy to operate.It is if soft using plastics above other body
Pipe, then the liquid gravity in one side body can deform flexible pipe, and another aspect human hand operation knob inevitably leads to soft
Pipe rocks, and deforms flexible pipe.Flexible pipe deformation can cause titration inaccurate, operating difficulties.Aspect connects on the utility model body
For non-deformed hard tube, the shape of hard tube is not invented change, overcome above mentioned problem.
Preferably, the cock body is ground glass stopper.
Preferably, the hard tube includes penetrating the glass tube of the cock body, the plastic pipe for connecting glass tube and connection plastic cement
The stainless steel tube of pipe.
Preferably, the hard tube extends downwardly from from body upper end.
Preferably, the obturating plug is polytetrafluoroethylene (PTFE) obturating plug, and the groove is in back taper, and rubber layer is coated with groove.
Preferably, in addition to fixing device, the fixing device include：
Iron stand；
The buret clamp being fixed on iron stand, the buret clamp fix the body；
The hard tube folder being fixed on iron stand, the hard tube folder include pole, and the end of pole is provided with clamp, and clamp is fixed
The hard tube, the middle part of the pole is in the horizontal direction to curving camber.
The utility model has the advantages that：
（1）Body and the sharp mouth of lower end are an entirety, are connected without sebific duct or glass cock, therefore be not required to smear all scholars
Woods, sharp mouth is avoided to block；
（2）Sharp mouth bubble is avoided to be not easy to discharge；
（3）It is easy to operate.
Additional aspect and advantage of the present utility model will be set forth in part in the description, partly by from following description
In become obvious, or by it is of the present utility model practice recognize.
Brief description of the drawings
Of the present utility model above-mentioned and/or additional aspect and advantage will in the description from combination accompanying drawings below to embodiment
Become obvious and be readily appreciated that, wherein：
Fig. 1 is the structural representation of the new acid buret of the utility model embodiment；
Fig. 2 is the structural representation of the new acid buret with fixing device of the utility model embodiment.
Description of reference numerals：
Body 1；Sharp mouth 2；Ground glass stopper 3；Glass tube 4；Plastic pipe 5；Stainless steel tube 6；Knob 7；Polytetrafluoroethylene (PTFE) plug
Seat 8；Rubber layer 9；Iron stand 10；Buret clamp 11；Pole 12；Clamp 13.
Embodiment
Embodiment of the present utility model is described below in detail, wherein from beginning to end same or similar label represent it is identical or
Similar element or the element with same or like function.The embodiments described below with reference to the accompanying drawings are exemplary,
It is intended to be used to explain the utility model, and it is not intended that to limitation of the present utility model.
The new acid buret according to the utility model embodiment described with reference to the accompanying drawings.Fig. 1,2 are this practicality
A kind of structural representation of new acid buret of new embodiment.It includes body 1, sharp mouth 2, ground glass stopper 3, glass
Pipe 4, glass tube 4, stainless steel tube 6, knob 7 and polytetrafluoroethylene (PTFE) obturating plug 8.
Body 1 and the sharp mouth 2 of lower section are integrally formed and are connected as an entirety, without sebific duct or glass cock.Set on body 1
Scale.
The upper seal of body 1 is plugged with ground glass stopper 3, and hard tube is passed through in ground glass stopper 3.Hard tube includes penetrating frosted glass
The glass tube 4 of glass plug 3, the plastic pipe 5 for connecting glass tube 4 and the stainless steel tube 6 for connecting plastic pipe 5.Stainless steel tube 6 is provided with rotation
Button 7, air capacity in hard tube is entered by the control of turn knob 7, so as to adjust liquid droping speed.
The one end of plastic pipe 5 connects glass tube 4, and the other end is bent downwardly, and knob 7 is located at the side of body 1, to facilitate people
