Abstract
The utility model discloses an acid burette capable of improving the measurement precision. The burette comprises a burette body, a piston sleeve and an operating piston, wherein a slide sleeve is installed on the burette body; the center of the front surface of the slide sleeve is provided with an amplification mirror; the back surface of the slide sleeve, opposite to the amplification mirror, is provided with a fine scale line and a liquid surface positioning line; and the operating piston is provided with a vertical large-diameter titrant passage and a vertical small-diameter titrant passage. The acid burette has the beneficial effects that since the acid burette is provided with the slide sleeve for precisely reading the liquid surface scale, the position of the liquid surface can be conveniently and rapidly judged, and the liquid surface scale can be more precisely determined and read. Since the operating piston is provided with two titrant passages of different diameters, the titrant passages can be selectively used in different stage of the titration operation.
Description
Technical field
The utility model relates to a kind of acid buret that can improve measuring accuracy.
Background technology
Buret is a kind of surveying instrument of titrimetry indispensability, just can very accurately calculate concentration and the concrete content of measured matter by known concentration of standard solution and the shown titrant consumption of buret.Existing buret in use exists following defective, it at first is the reason for the making aspect of observing, the scale of buret can not be too close, thereby many times when liquid level is between two scale marks, its concrete decimal place must be judged by naked eyes fully, occurs error especially easily.Be exactly the not so good control of size of terminal point drop in addition because the moving piston of the complete armrest of vs consumption in this time controlled, careless slightly will occur excessive, thereby can cause the increase of operate miss.
Summary of the invention
Goal of the invention of the present utility model is to provide a kind of acid buret that can improve measuring accuracy, uses this buret can significantly improve the degree of accuracy of titration operation.
The technical solution of the utility model is: this acid buret comprises the titration body, piston bush and the operated piston of titration body bottom.At the titration body slip cap of being made by transparent material is housed, magnifier is equipped with in the center in slip cap front, the slip cap back side relative with it indicates meticulous scale mark and liquid level position line, and operated piston is provided with vertically disposed particle size vs passage and thin footpath vs passage.
The beneficial effects of the utility model are: owing to be provided with for the slip cap that accurately reads the liquid level scale at this acid buret, can judge liquid level position quickly and easily, and can more accurately determine and read the liquid level scale.Owing to be provided with the vs passage of two kinds of different-diameters on the operated piston, can use in the different phase selectivity of titration operation.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in detail.
Fig. 1 is structural representation of the present utility model.
Number in the figure:
1, titration body 2, piston bush 3, operated piston 4, slip cap 5, magnifier
6, meticulous scale mark 7, liquid level position line 8, particle size vs passage 9, thin footpath vs passage.
Embodiment
Example
As shown in Figure 1, this acid buret comprises titration body 1, the piston bush 2 of titration body 1 bottom and operated piston 3.At titration body 1 slip cap 4 of being made by transparent material is housed, magnifier 5 is equipped with in the center in slip cap 4 fronts, slip cap 4 back sides relative with it indicate meticulous scale mark 6 and liquid level position line 7, and operated piston 3 is provided with vertically disposed particle size vs passage 8 and thin footpath vs passage 9.
