Description
Technical field
The present invention relates to chemical field, especially chemical apparatuses field, specially a kind of base buret.
Background technology
Base buret is the titration apparatus commonly used in analytical chemistry.The primary structure of traditional base buret tube head includes sebific duct and two parts of bead, and it controls the valve open philosophy to be：When the sebific duct near bead is extruded, certain cavity is formed between rubber tube inner wall and bead can allow liquid to pass through.
When titration operation is carried out, connection rubber tube in base buret lower end puts a bead to base buret in rubber tube, satiny due to aqueous slkali, bead is difficult to fix, and is slided in rubber tube and causes leak.Due to the defect of the structure, causing the failure probability of titration operation increases.
Therefore, in the urgent need to a kind of new device, to solve the above problems.
The content of the invention
Goal of the invention of the invention is：Rubber tube is connected for existing base buret lower end, a bead is put in rubber tube, it is satiny due to aqueous slkali, bead is difficult to fix, easily slided in rubber tube and cause leak, cause the titration operation failure increased problem of probability, there is provided a kind of base buret.Present inventive concept is ingenious, reasonable in design, easy to use, is prevented effectively from using bead and the construction of switch of rubber tube composition, can realize quick, the accurate addition of akaline liquid, effectively reduces the probability of titration operation failure.
To achieve these goals, the present invention is adopted the following technical scheme that：
A kind of base buret, including titration supervisor, titration side pipe, air bag, connecting tube, syringe, the bottom of the titration supervisor are provided with conical nozzle, the top of the titration supervisor and airbags；
The titration side pipe is L-shaped, and one end of the titration side pipe is connected with titration supervisor, and the other end of the titration side pipe is connected by connecting tube with syringe；
Graduation mark is provided with the titration supervisor, the tie point that the titration side pipe and titration are responsible for is located between zero graduation line and air bag.
For foregoing problems, the present invention provides a kind of base buret.In the present invention, to titrate supervisor, it is to avoid using rubber tube and bead as control valve, bead control is eliminated completely.In the present invention, fundamentally solve the problems, such as that rubber tube is slided and leak.During present invention work, gassy in syringe, by compressing gasbag, by alkali lye by conical nozzle suction titration supervisor；After suction, air bag restores to the original state, and base buret inner and outer air pressure is consistent, is spilt from titration supervisor so as to be prevented effectively from alkali lye；Then, by the push rod of pushing syringe, by the gas press-in titration supervisor in syringe, so as to realize the outflow of alkali lye, corresponding titration work is completed.In the present invention, the flow of alkali lye is controlled using syringe so that the present invention has the advantages that easily operated, can realize being slowly added dropwise for alkali lye；Meanwhile, by the scale and the scale of titration supervisor of syringe, the addition of designated volume liquid can be realized, improve the accuracy of liquid addition.
The inwall of the titration supervisor is provided with upper end annular projection, internal diameter of the internal diameter that the upper end ring-type is convexed to form less than titration supervisor.
Zero graduation line is arranged on the corresponding titration supervisor outer wall of upper end annular projection.Using which, at the zero graduation line of titration supervisor, the narrow pipe in one end is formed.Under conditions of given volume, caliber is smaller, and corresponding height is higher.Thus, at narrow pipe, the Volume Changes for judging liquid that can be more prone to by height change are advantageously implemented the accurate addition of liquid volume.Meanwhile, when liquid level is wide, it is unfavorable for keeping the main liquid in pipe of titration to be in horizontality so that error increases；And the present invention is due to using the design of narrow pipe, under the same conditions, can greatly reduce error, with preferable effect.
Also include being arranged on the lower end annular projection of titration supervisor's inwall, the lower end annular projection is located between conical nozzle and upper end annular projection.
The lower end annular projection corresponding titration be provided with graduation mark on supervisor's outer wall.Using which, upper end annular projection, lower end annular projection cooperate so that the volume of upper/lower terminal more easily reads, and are conducive to improving the accuracy for determining.Meanwhile, when the addition of quantitative liquid is carried out, by the structure, error can be effectively reduced, with preferable effect.
The upper end annular projection, lower end annular projection use with titration supervisor be integrally formed respectively.
The titration side pipe is used with titration supervisor and is integrally formed.
The connecting tube is rubber tube.In the present invention, rubber tube is the connecting tube as connection syringe, and it does not contain bead, is not contacted with alkali lye yet, effectively prevent the possibility of breakage.
The titration supervisor, titration side pipe are respectively adopted glass and are made.
In sum, by adopting the above-described technical solution, the beneficial effects of the invention are as follows：The present invention is prevented effectively from rubber connecting pipe, vierics and is used cooperatively by the design to base buret structure, the accurate dropwise addition of alkali lye can be realized, with preferable effect.Reasonable in design, low production cost of the invention, has the advantages that easy to operate, measurement result is accurate, with preferable application prospect.
