Abstract
The utility model discloses a micro-scale titration pipe suitable for both acid and alkali. The micro-scale titration pipe comprises a graduated tube and a liquid storage tube, wherein the bottom of the liquid storage tube is communicated with the graduated tube; a titration valve is arranged at the communicated parts of the liquid storage tube and the graduated tube; the lower part of the graduated tube takes the shape of a cone; a circular truncated cone-shaped acid and alkali-resistant floating body is arranged in the graduated tube; a magnet is arranged in the circular truncated cone-shaped acid and alkali-resistant floating body; an adjusting support rod is arranged on the outer side of the graduated tube; a sliding magnet, which is used for controlling the magnet and driving the acid and alkali-resistant floating body to move up and down, is arranged in the adjusting support rod. The micro-scale titration pipe has the advantages that the structure is simple; as the acid and alkali-resistant floating body is arranged in the graduated tube, and the sliding magnet arranged at the exterior of the graduated tube controls the up-down movement of the acid and alkali-resistant floating body, the flow rate of an acid/alkali liquid can be controlled; the micro-scale titration pipe can be used in both acid experiments and alkali experiments; the application range is wide; through external control of the sliding magnet, the purposes of accurate liquid removing and titrating are realized, and titrating error is reduced to a certain extent; the structure is reasonable and practical.
Description
Technical field
The utility model belongs to the chemical experiment equipment, is specifically related to the general microburette of a kind of soda acid.
Background technology
Commonly use two kinds of acid and alkali formulas in chemical titration analysis experiment at present, yet owing to having glass piston in acid buret, rubber sleeve is arranged in base buret, so in use, acid can not be used for the experiment of alkali, and the alkali formula can not be used for the experiment of acid, its use is restricted, and all exist and can not accurately control in acid and base buret, there is titration error, the error that some microtitration experiments are produced is just larger, easily causes some experiments unsuccessful, affects the judgement of experimental teaching or result.
Summary of the invention
The purpose of this utility model is to provide and a kind ofly can reduces titration error, improves the general microburette of soda acid of experiment degree of accuracy.
the technical scheme that realizes the utility model purpose is the general microburette of a kind of soda acid, comprise graduated tube and liquid storage pipe, the bottom of described liquid storage pipe is connected with described graduated tube, be provided with titration valve at described liquid storage pipe and described graduated tube connectivity part, the bottom of described graduated tube is conical the setting, be provided with round table-like acid and alkali-resistance buoyancy aid in described graduated tube, be provided with magnet in described round table-like acid and alkali-resistance buoyancy aid, be provided with in the outside of described graduated tube and adjust pole, be provided be used to controlling described magnet and driving the sliding magnet that the acid and alkali-resistance buoyancy aid moves up and down on described adjustment pole.
Be provided with scale on described adjustment pole.The utlity model has positive effect: simple in structure, the buoyancy aid that is provided with acid and alkali-resistance in graduated tube of the present utility model, and controlling it by the magnet of graduated tube outside moves up and down, and then complete control to the acid ﹠ alkali liquid flow, it can be used for the acid experiment, also can be used for the experiment of alkali formula, applied widely, and,, by the magnet external control, can pipette accurately the purpose of dropping liquid, reduced to a certain extent titration error, practicality rational in infrastructure.Further be provided with scale on adjustment pole, make the adjusting of magnet more accurate.
Description of drawings
For content of the present utility model is more likely to be clearly understood, below according to specific embodiment also by reference to the accompanying drawings, the utility model is described in further detail, wherein:
Fig. 1 is structural representation of the present utility model.
Embodiment
(embodiment 1)
Fig. 1 has shown a kind of embodiment of the present utility model, and wherein Fig. 1 is structural representation of the present utility model.
see Fig. 1, the microburette that a kind of soda acid is general, comprise graduated tube 1 and liquid storage pipe 2, the bottom of described liquid storage pipe 2 is connected with described graduated tube 1, be provided with titration valve 3 at described liquid storage pipe 2 with described graduated tube 1 connectivity part, the bottom of described graduated tube 1 is conical the setting, be provided with round table-like acid and alkali-resistance buoyancy aid 4 in described graduated tube 1, be provided with magnet 5 in described round table-like acid and alkali-resistance buoyancy aid 4, be provided with in the outside of described graduated tube 1 and adjust pole 6, be provided be used to controlling described magnet 5 and driving the sliding magnet 7 that acid and alkali-resistance buoyancy aid 4 moves up and down on described adjustment pole 6.
Be provided with scale on described adjustment pole 6.
during use, the standard solution of having demarcated is packed in liquid storage pipe, magnet is dropped to bottom, the time acid and alkali-resistance buoyancy aid round table-like just in time with conical graduated tube driving fit, open titration valve, solution enters in graduated tube, use titration valve to control the speed that imports solution, while making solution reach on graduated tube " 0 " scale, close titration valve, adjust the position of magnet, the acid and alkali-resistance buoyancy aid is moved up, make solution start to drip, adjust magnet according to the scale of adjusting on pole, liquid droping speed is reached want state to get final product, whole process is simple, and dropping liquid is controlled accurately, being fit to micro-dropping liquid situation uses.
Obviously, above-described embodiment of the present utility model is only for the utility model example clearly is described, and is not the restriction to embodiment of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here need not also can't give all embodiments exhaustive.And these belong to apparent variation or the change that connotation of the present utility model extends out and still belong to protection domain of the present utility model.
Claims (2)
1. microburette that soda acid is general, comprise graduated tube and liquid storage pipe, it is characterized in that: the bottom of described liquid storage pipe is connected with described graduated tube, be provided with titration valve at described liquid storage pipe and described graduated tube connectivity part, the bottom of described graduated tube is conical the setting, be provided with round table-like acid and alkali-resistance buoyancy aid in described graduated tube, be provided with magnet in described round table-like acid and alkali-resistance buoyancy aid, be provided with in the outside of described graduated tube and adjust pole, be provided be used to controlling described magnet and driving the sliding magnet that the acid and alkali-resistance buoyancy aid moves up and down on described adjustment pole.
