Description
Technical field
This utility model relates to a kind of chemical experiment device, especially a kind of chemical demonstrator device that can quantitatively add multiple solution.
Background technology
Quantitative liquid feeding apparatus conventional in existing chemical experiment generally comprises burette and liquid-transfering gun. But all there is some problems in above two equipment when actually used, such as when actually used, the operating process of burette is very loaded down with trivial details, and owing to the viewing angle of experimenter is changing always, therefore in the process of quantitative liquid feeding, certain error is often produced, thus affecting the result of experiment; And although liquid-transfering gun its accuracy for burette is higher, use also more convenient, but it not only can not add solution in use in a large number, and often add a solution and also need to change disposable tip, therefore its not only use cost is higher, also create to a certain extent use inconvenience
Utility model content
The purpose of this utility model is in that to overcome the deficiencies in the prior art, it is provided that a kind of easy to use, saves reagent, can quantitatively add the chemical demonstrator device of multiple solution.
This utility model is achieved through the following technical solutions:
A kind of chemical demonstrator device that can quantitatively add multiple solution, it is characterized in that: include an installing plate, the vertically-mounted reaction tube of difference and multiple liquid-adding tube in described installing plate, described reaction tube and liquid-adding tube all adopt transparent material, a piston that can pump all closely it is embedded with along liquid-adding tube inner edge in each liquid-adding tube, described piston lower surface forms cavity with liquid-adding tube inner edge, the lower end of this cavity is communicated with a side end of a catheter, the end side of described catheter is connected with reaction tube, and the surface of each described liquid-adding tube is all shaped with scale.
And, described reaction tube upper end close installation has a sealing-plug, is shaped with through hole, is closely set with the outer rim of described catheter in through hole in described sealing-plug.
And, the outer rim of described each catheter is mounted on the valve for controlling catheter opening and closing.
And, the clamping plate matched according to the external diameter of reaction tube and liquid-adding tube in described installing plate, often organize and between two clamping plate, block dress liquid-adding tube or reaction tube respectively.
And, described piston is positioned at the end above liquid-adding tube and is integrally shaped with a push-pull bar.
Advantage of the present utility model and having the benefit effect that
In this utility model, multiple liquid-adding tubes hold different reagent respectively, coordinate catheter can add different reaction reagents in reaction tube, the scale that liquid-adding tube outer rim is made facilitates operator to observe the change of amount of reagent, and operator promote piston to get final product quantitative interpolation chemical reagent by push-pull bar;The valve that catheter outer rim is made can effectively control connection and the closedown of liquid-adding tube and reaction tube, it is to avoid due to maloperation or the chemical reagent drippage that causes due to gravity; The clamping plate made in described installing plate are easy to installing and using of reaction tube and liquid-adding tube, and after experiment terminates, experimenter can pass through to loosen clamping plate and reaction tube and liquid-adding tube taken off respectively, convenient for collecting.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 be in Fig. 1 reaction tube and liquid-adding tube part partial sectional view.
Detailed description of the invention
By the examples below this utility model being elaborated, described embodiment is illustrative and not restrictive, it is impossible to limit protection domain of the present utility model with this.
A kind of chemical demonstrator device that can quantitatively add multiple solution, this utility model innovation is in that, including an installing plate 1, the vertically-mounted reaction tube 6 of difference and multiple liquid-adding tube 3 in described installing plate, described reaction tube and liquid-adding tube all adopt transparent material, a piston 10 that can pump all closely it is embedded with along liquid-adding tube inner edge in each liquid-adding tube, described piston lower surface forms cavity with liquid-adding tube inner edge, the lower end of this cavity is communicated with a side end of a catheter 8, the end side of described catheter is connected with reaction tube, the surface of each described liquid-adding tube is all shaped with scale 9.
Described reaction tube upper end close installation has a sealing-plug 7, is shaped with through hole, is closely set with the outer rim of described catheter in through hole in described sealing-plug.
The outer rim of described each catheter is mounted on the valve 5 for controlling catheter opening and closing.
The clamping plate 4 matched according to the external diameter of reaction tube and liquid-adding tube in described installing plate, often organize and block dress liquid-adding tube or reaction tube between two clamping plate respectively.
Described piston is positioned at the end above liquid-adding tube and is integrally shaped with a push-pull bar 2.
Use procedure of the present utility model is:
When this utility model uses, experimenter first by reaction tube and liquid-adding tube respectively through Boards wall in installing plate, then pass through sealing-plug and with catheter, both connected, now valve closing; Afterwards the piston of liquid-adding tube is extracted, and be added thereto to different chemical reagent, will can carry out experimental implementation after piston seal afterwards; In operation, experimenter, first by valve opening, can add corresponding reagent by pressing push-pull bar afterwards, and in adding reagent process, experimenter can pass through the scale quantitative adjusting reagent made on liquid-adding tube; After experiment completes, reaction tube and liquid-adding tube are taken cleaning by operator respectively can complete whole experimentation.
In this utility model, multiple liquid-adding tubes hold different reagent respectively, coordinate catheter can add different reaction reagents in reaction tube, the scale that liquid-adding tube outer rim is made facilitates operator to observe the change of amount of reagent, and operator promote piston to get final product quantitative interpolation chemical reagent by push-pull bar; The valve that catheter outer rim is made can effectively control connection and the closedown of liquid-adding tube and reaction tube, it is to avoid due to maloperation or the chemical reagent drippage that causes due to gravity; The clamping plate made in described installing plate are easy to installing and using of reaction tube and liquid-adding tube, and after experiment terminates, experimenter can pass through to loosen clamping plate and reaction tube and liquid-adding tube taken off respectively, convenient for collecting.
