Abstract
The problem of the utility model discloses a kind of burette being easy to Z-operation of chemical analysis field, is returned to zero at present to Z-operation by manually adding and subtracting test solution with solution, and work efficiency is low.It includes titration tube body, and the small sircle hole of a diameter of 1 3mm is provided with the zero graduation line of titration tube body side wall, and the lower section of small sircle hole is concordant with zero graduation line.When the utility model operates, first visual titration liquid is attached to more than zero graduation line, wiped again with a clean experiment rag in small sircle hole hole edge against buret body outer wall, due to the tension force of liquid, titrating solution is quickly suctioned out by small sircle hole by rag, and liquid level is down at the lower section of small sircle hole, automatic aligning zero graduation line, it is easy to operate, it is time saving and energy saving.
Description
Technical field
It the utility model is related to a kind of burette being easy to Z-operation of chemical analysis field.
Background technology
Buret is most common a kind of analysis detection instrument in assay laboratory's humid analysis.It is first in titrimetry
First need volumetric soiutions being added in buret, test solution is filled it up near zero graduation line, adjustment liquid level is put down with zero graduation line
Titrimetry is carried out again after neat.All it is by manually carrying out plus-minus test solution zeroing, being regarded since manual operation exists to Z-operation now
Power error, returning to zero could complete sometimes for repeatedly 3-5 times, and work efficiency is low.
Utility model content
The purpose of the utility model is to overcome prior art defect, there is provided a kind of new titration being easy to Z-operation
Pipe.
What the technical solution of the utility model was realized in：A kind of burette being easy to Z-operation, including drop
Fixed tube body, it is, a small sircle hole, lower section and zero quarter of small sircle hole are provided with the zero graduation line of titration tube body side wall
It is concordant to spend line.
Preferably, a diameter of 1-3mm of the small sircle hole.
When the utility model operates, first visual titration liquid is attached to more than zero graduation line, then with a clean experiment rag small
Circular hole hole edge is wiped against buret body outer wall, and due to the tension force of liquid, titrating solution is quick by rag by small sircle hole
Suction out, liquid level is down at the lower section of small sircle hole, and automatic aligning zero graduation line is easy to operate, time saving and energy saving.
Brief description of the drawings
Fig. 1 is the utility model structure diagram.
In figure, 1-bucket opening；2-titration tube body；3-small sircle hole.
Embodiment
It is further described below in conjunction with the accompanying drawings：
As shown in Figure 1, the titration tube body of bucket opening 1 is arranged at a kind of burette being easy to Z-operation, including top
2, the small sircle hole 3 of an a diameter of 2mm, lower section and zero quarter of small sircle hole 3 are provided with the zero graduation line of titration 2 side wall of tube body
It is concordant to spend line.
When the utility model operates, first visual titration liquid poured into from bucket opening 1 be attached to zero graduation line slightly on, it is then clean with one
Experiment rag is wiped in 3 hole edge of small sircle hole against titration 2 outer wall of tube body, and due to the tension force of liquid, titrating solution passes through small
Circular hole 3 is quickly suctioned out by rag, and liquid level is down at the lower section of small sircle hole 3, automatic aligning zero graduation line, easy to operate, time saving
It is laborsaving.
Claims (2)
1. a kind of burette being easy to Z-operation, including titration tube body, it is characterised in that：In titration tube body side wall
Zero graduation line at be provided with a small sircle hole, the lower section of small sircle hole is concordant with zero graduation line.
A kind of 2. burette being easy to Z-operation according to claim 1, it is characterised in that：The small sircle hole is straight
Footpath is 1-3mm.
