Description
Technical field
The utility model relates to synthetic reaction experimental assembly technical field, specifically refers to a kind of resins synthesis reaction experiment sampler.
Background technology
In resins synthesis experiment reaction, in order to follow the tracks of the process of reaction, detecting the degree of polymerization of resin, usually needing to sample in course of reaction, sample is analyzed.Existing sampling mode is opened by the mouth of experiment reaction bulb, suction pipe or other sampler stretched in reactant liquor and sample.This sampling mode troublesome poeration, when opening charging aperture, reaction dissolvent is easy to evaporate, and toxic and volatile solvents for some, cause certain injury to human body; Need the reaction of inert gas shielding, open the sampling of reaction bottleneck, can air be introduced, cause subsidiary reaction in reaction to occur; Opening mouth in addition can cause temperature of reaction to change, and is unfavorable for normally carrying out of reaction.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art and proposes a kind of resins synthesis reaction experiment sampler, its whole sampling process is among sealing state, reaction dissolvent can not be evaporated, air can not be introduced, the temperature of reaction can not be affected, also can not cause harmful effect to reaction, there is advantage simple to operate.
To achieve these goals, the technical scheme taked of the utility model is as follows:
The utility model proposes a kind of resins synthesis reaction experiment sampler, comprise scale sampling jar and sampling catheter, the openend of described scale sampling jar upward and the diameter of openend is less than body, the open end of described scale sampling jar is provided with ear washing bulb, the bottom of described scale sampling jar is connected with an elongated conduit, and the end of described conduit is provided with ground external tapping; Described sampling catheter is elongated rod-shaped thing, the top diameter of sampling catheter is greater than all the other positions, the tip position of sampling catheter is provided with ground inner joint, described scale sampling jar is connected with described sampling catheter ground, the afterbody of sampling catheter to stretch within reaction bulb and is placed in below liquid level, described sampling catheter is also provided with the first cock near ground inner joint place, described conduit is also provided with the second cock near ground external tapping place.
Further, also comprise rubber stopper, described rubber stopper is sealed in the exit of reaction bulb.
The beneficial effects of the utility model: compared with prior art, whole sampling process of the present utility model is under the state of a sealing, make the volatilization that can not cause solvent when sampling like this, the particularly volatilization of toxic solvent, ensure that the health of people when testing, meanwhile, due to the generation that air avoids subsidiary reaction can not be introduced under sealing state, when making to sample, the temperature be in reaction can not change, and ensure that normally carrying out of reaction.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of resins synthesis reaction experiment of the utility model sampler.
Wherein, 1-scale sampling jar, 2-sampling catheter, 3-ear washing bulb, 4-conduit, 5-first cock, 6-second cock, 7-rubber stopper, 8-reaction bulb.
Embodiment
For making the object of the utility model embodiment, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in the utility model embodiment, technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, the utility model proposes a kind of resins synthesis reaction experiment sampler, comprise scale sampling jar 1 and sampling catheter 2, scale sampling jar 1 and sampling catheter 2 are linked together by ground, the openend of described scale sampling jar 1 upward and the diameter of openend is less than body, the open end of described scale sampling jar 1 is provided with ear washing bulb 3, and the bottom of described scale sampling jar 1 is connected with an elongated conduit 4, and the end of described conduit 4 is provided with ground external tapping; Described sampling catheter 2 is elongated rod-shaped thing, the top diameter of sampling catheter 2 is greater than all the other positions, the tip position of sampling catheter 2 is provided with ground inner joint, described scale sampling jar 1 is connected with described sampling catheter 2 ground, the afterbody of sampling catheter 2 to stretch within reaction bulb 8 and is placed in below liquid level, described sampling catheter 2 is also provided with the first cock 5 near ground inner joint place, described conduit 4 is also provided with the second cock 6 near ground external tapping place.In addition, in order to ensure the sealing effectiveness when sampling, be also provided with a rubber stopper 7 in the exit of reaction bulb 8, sampling catheter 2 to be extend in reaction bulb by rubber stopper 7 and is in the below of liquid level.
The utility model structure and simple to operate, can ensure that sampling process is carried out under being in a totally sealed environment, detailed process is as follows: before entry into the trial, sampling catheter 2 is connected with reaction bulb 8 by rubber stopper 7, sampling catheter 2 afterbody extend into below reaction liquid level, now, the first cock 5 switch on sampling catheter 2 is closed condition.When reaction is carried out afterwards and need sample, scale sampling jar 1 is passed through the interface of ground connection to sampling catheter 2 top, after installing, by the second cock 6 switch opens on described scale sampling jar 1, draw air in scale sampling jar 1 with ear washing bulb 3, it is made to be in negative pressure state, then, slowly open the first cock 5 switch on sampling catheter 2, allow sample slowly be drawn in scale sampling jar 1, if sampling amount is inadequate, reactant liquor can be drawn with ear washing bulb 3 again.After sampling amount meets analysis requirement, the first cock 5 switch and the second cock 6 switch are closed respectively, removed by scale sampling jar 1, releasing sample in bottle can analyze.Secondary and when later sampling, repeats aforesaid operations, draws reactant liquor sample in scale sampling jar 1, then puts in reaction bulb again, in triplicate, then remove scale sampling jar 1, take out liquid in it and analyze.When reaction needs inert gas shielding; by inert gas tubes connection to scale sampling jar 1 top open part; after air in the complete bottle of inert gas replacement; again scale sampling jar 1 is connected to sampling catheter 2 top; open the switch that 5 passes and the second cock 6 are opened in the first cock, with inert gas liquid in pipe blown back and flow in reaction bulb 8, when reaction does not need inert gas shielding; the first cock 5 switch can be opened, allow liquid in pipe be back in reaction bulb 8.Whole sampling process of the present utility model is under the state of a sealing, make the volatilization that can not cause solvent when sampling like this, the particularly volatilization of toxic solvent, ensure that the health of people when testing, simultaneously, owing to can not introduce the generation that air avoids subsidiary reaction under sealing state, when making to sample, the temperature be in reaction can not change, and ensure that normally carrying out of reaction.
Only as described above, be only the preferred embodiment of the utility model, certainly the scope of this novel enforcement can not be limited with this, namely generally make simple equivalence change according to the content described in the utility model claim and utility model instructions and modify, all still belong within the utility model claim scope.In addition, summary part and title are only used to the use of auxiliary patent document search, are not used for the interest field of restriction the utility model.
