Abstract
The utility model discloses a universal type capacity analysis burette, which comprises a glass tube (1) with scales, a flow regulator (2) and a polytetrafluoroethylene (or polyethylene) capillary drip nozzle (3). The glass tube (1), the flow regulator (2) and the polytetrafluoroethylene (or polyethylene) capillary drip nozzle (3) are connected in series through a polytetrafluoroethylene (or polyethylene) infusion catheter (4). The burette is convenient to operate, can be used for titrating acid and alkali, can control a small titration volume, and the problems that a switch of an acid burette can easily cause leakage and a latex tube of an alkali burette can be easily corroded are solved.
Description
Technical field
The utility model relates to experiment utensil commonly used in a kind of chemical laboratory, refers to a kind of universal buret that is used for volumetry particularly.
Background technology
At present, the quantitative chemical analysis of constant is usually with acid buret or base buret, the easy leakage of the switch of acid buret, and the emulsion tube of base buret is corroded easily, and the inconvenient operation of these two kinds of burets, thereby influence the degree of accuracy and the accuracy of quantitative test.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art, provides a kind of simple in structure, is convenient to operation, can control the universal buret of small adding volume.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of volumetry buret, comprise the glass tube of being with scale, flow regulator, teflon (or tygon) capillary drip nozzle, by teflon (or tygon) transfusion catheter they are cascaded, it is characterized in that: the volume of vs is controlled by flow regulator.
Advantage of the present utility model is: the utility model is universal volumetry buret, has solved the problem that the emulsion tube of the easy leakage of switch of acid buret and base buret is corroded easily.The utility model is easy to operate, can control small titration volume, has improved the degree of accuracy and the accuracy of quantitative test.
Description of drawings
Fig. 1 is a structural representation of the present utility model.1 glass tube among the figure for the band scale, 2 is flow regulator, and 3 is teflon (or tygon) capillary drip nozzle, and 4 is teflon (or tygon) transfusion catheter.
Embodiment
