Abstract
The present invention provides a laboratory glassware cleaning agent and its preparation method, the laboratory glassware cleaning agent is composed of the following components by weight: 62%-68% of sulfuric acid, 62%-68% of hydrogen peroxide and 32%-38% of water, and the weight ratio of sulfuric acid to hydrogen peroxide is 1:1; the preparation method of the laboratory glassware cleaning agent is as follows: first, preparing a sulfuric acid and hydrogen peroxide mixed solution with the weight ratio of sulfuric acid to hydrogen peroxide of 1:1, to be more specific, weighing the sulfuric acid and the hydrogen peroxide at the mass ratio of 1:1, while stirring, slowly adding the sulfuric acid to the hydrogen peroxide to sulfuric acid hydrogen peroxide; while stirring, slowly adding the slowly adding into a certain amount of beforehand-prepared water, continuing stirring for 5 minutes to obtain the laboratory glassware cleaning agent. The laboratory glassware cleaning agent can simply, rapidly, and thoroughly clean grease and other dirt on the glass glassware surface.
Description
Technical field
The present invention relates to clean-out system that a kind of chemical laboratory uses and preparation method thereof, particularly relate to a kind of laboratory glassware detergent for trace and trace analysis and preparation method thereof.
Background technology
Clean glassware at chemical laboratory, one of main preparation work before experiment, especially in trace and trace analysis, usually due to glassware, as: volumetric flask, flask, transfer pipet etc. clean not thorough, and the accuracy of impact analysis result and repeatability.Existing laboratory glassware detergent uses commercially available washing powder, liquid detergent etc. conventionally, cannot thoroughly clean up for being attached to the lip-deep oil stain of glassware and other dirts, and preparation method's more complicated of these clean-out systems.
As can be seen here, above-mentioned existing laboratory glassware detergent and preparation method thereof in the use, obviously still has inconvenience and defect, and is urgently further improved.The problem existing in order to solve laboratory glassware detergent and preparation method thereof, relevant manufacturer there's no one who doesn't or isn't seeks solution painstakingly, but have no for a long time applicable design is completed by development always, and common product does not have appropriate product to address the above problem, this is obviously the problem that the anxious wish of relevant dealer solves.Therefore how to found a kind of oil stain on glassware surface and novel laboratory glassware detergent of other dirts and preparation method thereof of cleaning simply, fast, up hill and dale, real one of the current important research and development problem that belongs to, also becoming the current industry utmost point needs improved target.
Because the defect that above-mentioned existing laboratory glassware detergent and preparation method thereof exists, practical experience and the expertise of the inventor based on being engaged in this type of product design manufacture and enriching for many years, and the utilization of cooperation scientific principle, actively research and innovation in addition, to founding a kind of novel laboratory glassware detergent and preparation method thereof, can improve general existing laboratory glassware detergent and preparation method thereof, make it have more practicality.Through constantly research, design, and after repeatedly studying sample and improving, finally create the present invention who has practical value.
Summary of the invention
The object of the invention is to, overcome the defect that existing laboratory glassware detergent and preparation method thereof exists, and provide a kind of novel laboratory glassware detergent and preparation method thereof, technical problem to be solved is to make its oil stain that cleans simply, fast, up hill and dale glassware surface and other dirt, thereby is more suitable for practicality.
The object of the invention to solve the technical problems realizes by the following technical solutions.According to a kind of laboratory glassware detergent provided by the invention, wherein formed by following component and weight percent: sulfuric acid and hydrogen peroxide, wherein sulfuric acid: hydrogen peroxide=1:1, their weight percentage ranges is 62%-68%; And water, wherein the weight percentage ranges of water is 32%-38%.
The object of the invention to solve the technical problems also can be applied to the following technical measures to achieve further.
Aforesaid laboratory glassware detergent, wherein said sulfuric acid and hydrogen peroxide are analytical pure chemical reagent, and water is the purified water such as distilled water, deionized water.
The object of the invention to solve the technical problems also realizes by the following technical solutions.The preparation method of a kind of laboratory glassware detergent proposing according to the present invention, wherein preparation process is as follows: first prepare sulfuric acid and hydrogen peroxide mixed solution that weight ratio is 1:1,1:1 takes sulfuric acid and hydrogen peroxide in mass ratio, under constantly stirring, sulfuric acid is slowly added in hydrogen peroxide; Then mixed solution, under constantly stirring, be slowly added in preprepared a certain amount of water, continue to stir 5 minutes, obtain laboratory glassware detergent of the present invention.
The present invention compared with prior art has obvious advantage and beneficial effect.By technique scheme, laboratory glassware detergent of the present invention and preparation method thereof can reach suitable technical progress and practicality, and has the extensive utility value in industry, and it at least has following advantages: preparation method is simple, clean the effective of glassware, speed is fast.If with this clean-out system immersion glassware, be 40-45 ° of C in temperature range, soak time is 10-15 minute, and cleaning performance can be better.
In sum, the present invention has significant progress technically, and has obvious positively effect, is really a new and innovative, progressive, practical new design.
Above-mentioned explanation is only the general introduction of technical solution of the present invention, in order to better understand technique means of the present invention, and can be implemented according to the content of specification sheets, and for above and other object of the present invention, feature and advantage can be become apparent, especially exemplified by preferred embodiment, be described in detail as follows below.
