According to the utility model, the metastasis and measurement of a little of liquid reagent of the strong corrosivity concentrated sulphuric acid may be performed in an enclosed system, such that it is possible to reduce damage of the strong corrosivity reagent to human body and articles greatly, and to fetch concentrated sulphuric acid safely, conveniently and rapidly.
Description
Technical field
The utility model relates to a kind of charger of chemical laboratory special use, particularly relates to a kind of safety-type concentrated sulfuric acid charger.
Background technology
The reagent concentrated sulfuric acid is all used to some extent in many necks city, especially in the teaching practice and scientific research of specialty chemical.The reagent concentrated sulfuric acid is filled in usually in the vial of 500ML and stores, and when needing, is removed and transfers in other container.The concentrated sulfuric acid is to have the corrosive chemicals of extra-heavy, and people get in the liquid process by its damage health or clothing through the concentrated sulfuric acid of being everlasting.It mainly is because accident is splashed and leak accidentally that the concentrated sulfuric acid is got in the liquid process injury to people and thing.Because the concentrated sulfuric acid has severe corrosive, therefore, we need be with the acid-proof gloves when using it, very inconvenient, and especially concentrating at needs can influence the experiment progress when repeatedly taking.Patent CN2283858Y, CN2744350Y and CN201002023Y have invented and can be used for the quick charger that Biochemical Research is analyzed, but do not consider the severe corrosive of the concentrated sulfuric acid, patent CN2241142Y invention is used for the charger of vinegar and wine liquid, CN2615121Y has designed the automatic type charger, but their complex structure, therefore being not suitable for experiment uses, CN2039229U improves the charger of having invented a kind of suitable chemical analysis quantitative liquid getting to DRP, but need select different special measuring tools for use during owing to use, therefore caused the inconvenience of using, CN86201412 has invented suitable pneumatic type charger simple in structure, can't accurately quantitative deficiency but still have, and need can't definitely avoid splashing of the concentrated sulfuric acid and overflow letting out for the continuous liquid feeding of liquid holding bottle.Germany Eppendorf AG (http://www.eppendorf.cn/http: //www.eppendorf.cn/) a kind of charger weak solution of sale, and price height (2000 yuan/platform); Germany Brand company (http://www.brand.de/de/http: //www.bran electron titration device, 7000 yuan/platform of price obviously should not be made concentrated sulfuric acid liquid feeding and use; A kind of glass charger is sold by Shanghai Rong Tai Biochemical Engineering Co., Ltd, safety inadequately when this charger is used for the concentrated sulfuric acid.The principle that we have used for reference the advantage of above patent and micro titrator successfully designs and has made a cover " safety-type concentrated sulfuric acid liquid getting device ", by in practice application in the past few years, proves that this cover instrument is real safe and reliable.
The utility model content
Technical problem to be solved in the utility model provides a kind of transfer of the gobbet reagent that makes the severe corrosive concentrated sulfuric acid and measures in the system that is in a sealing carries out, reduced of the injury of severe corrosive reagent greatly, realized that the concentrated sulfuric acid gets safe, the safety-type concentrated sulfuric acid charger easily and fast of liquid human body and article.
In order to solve the problems of the technologies described above, the safety-type concentrated sulfuric acid charger that the utility model provides, the draught excluder that has screw socket can be installed on the reagent bottle, reagent bottle is placed on the fixator, described draught excluder is provided with the catheter of calming the anger conduit and being communicated with the reagent bottle bottom liquid that is communicated with reagent bottle top air chamber, the described conduit of calming the anger is connected with pressurizer, the liquid outlet of described catheter docks with save-all, the bottom of described save-all is communicated with the constant volume device by proportional valve, and described constant volume device docks with beaker by bleeder valve.
The bottom of described save-all is communicated with by the bottom of proportional valve with described constant volume device.
Adopt the safety-type concentrated sulfuric acid charger of technique scheme, the transfer and measuring in the system that is in a sealing of the gobbet reagent of the severe corrosive concentrated sulfuric acid is carried out, thereby reformed the transfer of gobbet reagent and measured mode, reduced of the injury of severe corrosive reagent greatly human body and article with severe corrosive.The draught excluder screw socket can with commercially available concentrated sulfuric acid reagent bottle coupling, therefore, after the concentrated sulfuric acid uses up, can directly change reagent and needn't topple over, thereby overcome unsafe factor fully.This device is to take the concentrated sulfuric acid quantitatively.The material that key position is selected for use is the corrosion-resistant polytetrafluoroethylene (PTFE), and the frangible acid solution that causes that has overcome glass material is revealed.(annotate: polytetrafluoroethylmaterial material can 328 ℃ of compression moldings).Trade mark on the reagent bottle can be by not stained.In a word, realized that the concentrated sulfuric acid gets the safe, easily and fast of liquid.
The characteristics of this instrument are:
1, used a specially designed draught excluder, both can stop concentrated sulfuric acid suction, can from reagent bottle, draw the concentrated sulfuric acid again.
2, collect the end designed a save-all, prevent to splash when the concentrated sulfuric acid from drawing, guaranteed end user's safety.
3, design one and quantitatively measured device, can quantitatively measure concentrated sulfuric acid reagent safely.
4, by the combination of above each parts, acid solution is to be in the system of sealing when having realized taking the concentrated sulfuric acid of amount of reagent, can not produce any splashing.
In sum, the utility model is that a kind of transfer of the gobbet reagent that makes the severe corrosive concentrated sulfuric acid and measuring in the system that is in a sealing is carried out, reduced of the injury of severe corrosive reagent greatly, realized that the concentrated sulfuric acid gets safe, the safety-type concentrated sulfuric acid charger easily and fast of liquid human body and article.
