Abstract
The invention discloses a quantitative filling test tube. The test tube comprises a test tube body. The test tube body comprises a cylindrical glass tube. The lower part of the glass tube is an arc bottom. The radian of the arc bottom is 2.14. The top of the glass tube is provided with a filling pipe. A plug is arranged in the top end of the filling pipe. The filling pipe is a cylindrical pipe. The bottom of the filling pipe is provided with a tapered bottom, and the radian of the tapered bottom is 1:1.36. The lower end of the filling pipe is sleeved in the glass tube. A rubber sealing ring is arranged between the external wall of the filling pipe and the internal wall of the glass tube. The quantitative filling test tube has the advantages that the shortages of prior art can be overcome, and the structural design is reasonable and novel.
Description
Technical field
The present invention relates to a kind of quantitative filling test tube, belong to teaching equipment field.
Background technology
Test tube, the instrument that chemical laboratory is conventional, serve as the reaction vessel of a small amount of reagent, when room temperature or heating, (should preheat before heating, not so test tube easily bursts.) use.Test tube divides common test tube, tool test tube, centrifuge tube etc. multiple.In teaching demonstration is tested, a lot of chemical experiments are to need the strict mixing ratio controlling two kinds of liquid, but in actual mechanical process, if quantitative dropper or quantitative measuring bottle, are difficult to control mixed proportion, the effect of impact experiment.
Summary of the invention
The deficiency existed for prior art, the technical problem to be solved is to provide a kind of quantitative filling test tube, easy to use, and quantitative filling increases the demonstrating effect of experiment.
For solving above-mentioned technical problem, the present invention adopts the technical scheme that, a kind of quantitative filling test tube, including test tube body, test tube body includes a cylindrical glass tubing, and glass tubing bottom is arc bottom, and the radian of arc bottom is 2.14；The top of described glass tubing is provided with a filler pipe, and filler pipe top is provided with a sealing plug；Described filler pipe is cylindrical tube, and the bottom of filler pipe is provided with a tapered bottom end, and the tapering of tapered bottom end is 1:1.36；The lower end socket of described filler pipe, with in glass tubing, is provided with rubber seal ring between outer wall and the inwall of glass tubing of filler pipe；Being provided with a through hole on the cone point of described tapered bottom end, be provided with a dropper in filler pipe, dropper passes sealing plug and the through hole of tapered bottom end, is provided with rubber seal ring between dropper and through hole；Some liquid outlets, dropper sealed bottom it is provided with in the middle part of described dropper；It is provided with some filling scales on described filler pipe, sealing plug is provided with air-vent.
Optimizing, above-mentioned quantitative filling test tube, the top of described dropper is provided with rubber sacculus.
It is an advantage of the current invention that it can overcome the drawback of prior art, reasonable in design is novel.The technical scheme of the application is in actual use, first press down on dropper, it is that through hole blocked by dropper, then by the extruding of sacculus, the compound in dropper is clamp-oned in filler pipe by liquid outlet, observe the filling scale on filler pipe, when, after the component being filled into needs, stopping extruding rubber sacculus, dropper is pulled upwardly on, dropper is departed from through hole, and liquid is added dropwise in glass tubing along through hole.The convenient liquid measure controlling filling of such mode, to ensure experiment effect.

Fig. 1 is the structural representation of the present invention；
In figure: 1 be glass tubing, 2 be arc bottom, 3 be filler pipe, 4 be sealing plug, 5 be tapered bottom end, 6 be rubber seal ring, 7 be through hole, 8 be liquid outlet, 9 be filling scale, 10 be rubber sacculus, 11 for air-vent.
Detailed description of the invention
The technical characterstic of the present invention is expanded on further below in conjunction with the accompanying drawings with specific embodiment.
The present invention is a kind of quantitative filling test tube, and including test tube body, test tube body includes a cylindrical glass tubing, and glass tubing bottom is arc bottom, and the radian of arc bottom is 2.14；The top of described glass tubing is provided with a filler pipe, and filler pipe top is provided with a sealing plug；Described filler pipe is cylindrical tube, and the bottom of filler pipe is provided with a tapered bottom end, and the tapering of tapered bottom end is 1:1.36；The lower end socket of described filler pipe, with in glass tubing, is provided with rubber seal ring between outer wall and the inwall of glass tubing of filler pipe；Being provided with a through hole on the cone point of described tapered bottom end, be provided with a dropper in filler pipe, dropper passes sealing plug and the through hole of tapered bottom end, is provided with rubber seal ring between dropper and through hole；Some liquid outlets, dropper sealed bottom it is provided with in the middle part of described dropper；It is provided with some filling scales on described filler pipe, sealing plug is provided with air-vent.The top of described dropper is provided with rubber sacculus.
It is an advantage of the current invention that it can overcome the drawback of prior art, reasonable in design is novel.The technical scheme of the application is in actual use, first press down on dropper, it is that through hole blocked by dropper, then by the extruding of sacculus, the compound in dropper is clamp-oned in filler pipe by liquid outlet, observe the filling scale on filler pipe, when, after the component being filled into needs, stopping extruding rubber sacculus, dropper is pulled upwardly on, dropper is departed from through hole, and liquid is added dropwise in glass tubing along through hole.The convenient liquid measure controlling filling of such mode, to ensure experiment effect.
Certainly, described above is not limitation of the present invention, and the present invention is also not limited to the example above, those skilled in the art, in the essential scope of the present invention, the change made, retrofits, adds or replaces, all should belong to protection scope of the present invention.
