Abstract
The invention provides a folding method of a filter paper overcoming deficiencies of existing technology and a use method of a filter paper molding material obtained by using the folding method of the filter paper. The folding method of the filter paper includes the following steps: pair folding the filter paper to a semicircle, and then pair folding the semicircle to a right-angled sector. The folding method of the filter paper is characterized by pair folding the filter paper to the semicircle, and then pair folding the semicircle to the right-angled sector, and then opening one face of the right-angled sector, and folding and forming along a half position of the right-angled sector to the filter paper face. By adopting the folding method of the filter paper, folding steps can be simplified, filtering steps is simplified, space utility rate of a working table is improved, and finally experiment efficiency is achieved.
Description
Technical field
The present invention relates to a kind of for chemical or the method for folding of Bioexperiment filter paper and the article shaped after this folding using method.
Background technology
At present, researcher is carrying out in many experimentations, all relate to and filtered a step, conventional filter type uses filter paper and funnel to carry out filtration operation, concrete way is placed in funnel by the filter paper article shaped after folding through twice, and then be filled in the container such as volumetric flask or conical flask, be then transferred in the bottle of storage solutions and analysis use is carried out to sample.As the improvement of aforementioned folded filter paper method, there are four fold method and sixteen fold method (fan-folded method).
Conventional filter type is that the filter paper folded is put in funnel, then solution to be filtered is filled in the containers such as conical flask, and then in the solution bottle transferring to storage solutions, analysis is carried out to sample and use, this kind of filter type at least needs one, funnel, filter paper one, solution bottle one.
Prior art has the following disadvantages: (1), take up room large, and when carrying out a large amount of filtration experiment, can not filter the sample of greater number in the useful space, its space availability ratio is lower, shown in accompanying drawing 2; (2), must use funnel, the equipment of relative usage is many, adds the complexity of step; (3), that fan-folded method folds difficulty is relatively high, takes longer.
Summary of the invention
The invention provides a kind of overcome prior art deficiency folded filter paper method and the using method of the folding filter paper article shaped obtained in this way.
The method for folding of a kind of filter paper of the present invention, comprises the steps: by filter paper to being folded into semicircle, then semicircle is fan-shaped to being folded into right angle, then is opened in fan-shaped for right angle face, along this right angle covering of the fan 1/2nd place to folding forming in paper.
The using method of shaping filter paper of the present invention is: first by filter paper to being folded into semicircle, again that semicircle is fan-shaped to being folded into right angle, again fan-shaped for right angle face is opened, along this right angle covering of the fan 1/2nd place to folding forming in paper, in the bottleneck again sharp corner of folding forming thing being inserted volumetric flask or conical flask or beaker mouth, the upper limb of folding forming thing is opened, funnel can not be used directly to carry out filtration operation.
Tool of the present invention has the following advantages:
1) folding mode is relatively simple, although a step more than twice jackknife method of the prior art, simply many compared with sixteen fold method.
2) adopt the present invention can not re-use funnel and carry out Simple filter operation.
3) the present invention can simplify filtration operation process, eliminating filter paper, to put into funnel water moistening and extrude bubble and pour solution bottle two step into by conical flask, a conical flask and a funnel can be saved simultaneously, both decrease the quantity of scrubbing of Experimental Establishment, and can save time again.
4) space availability ratio of work top can be improved.
Accompanying drawing explanation
Fig. 1 is folded filter paper method of the present invention signal.Fig. 2 is for adopting traditional filtering mode and adopting method of the present invention to carry out the contrast of simple and easy coarse filtration time space utilization rate, and wherein the left side of figure is the space hold situation of prior art, and the right is space hold situation when adopting of the present invention.Fig. 3 is the use schematic diagram of the filter paper folded through the inventive method.
Detailed description of the invention
The present invention explains orally below in conjunction with accompanying drawing.
In Fig. 1, a to f illustrates the process of folded filter paper of the present invention.Concrete jackknife method is as follows: first by filter paper along a diameter doubling, obtain the semi-circular shape as Fig. 1 b shows.Again along the line of symmetry of semicircle be folded into as Fig. 1 c show fan-shaped.Fan-shaped top is pulled open, in Fig. 1 D-shaped shape.Hereto be existing step.Sector 135(be may also be other any one covering of the fan, as 345, etc.) along its center line, namely the line of symmetry 36 of sector 135 is to the folded inside of paper, is shaped to figure shown in Fig. 1 e.So far, folded filter paper of the present invention completes.The sharp corner of aforesaid folded filter paper article shaped is inserted in volumetric flask bottleneck, more suitably pulls open its upper limb, see Fig. 3, liquid to be filtered can be poured in it and carry out simple and easy coarse filtration operation.Because folding mode of the present invention is formed multiple folding, filter paper is had certain rigidity, therefore can not use funnel to filter.Applicant uses the present invention directly to carry out filtration operation, has successfully filtered 1,000 multiple samples, does not occur the situation of an example exception.
Through the measuring and calculating of reality, the method for folding used time of the present invention will be less than sixteen fold method, and concrete condition is in table 1.
In addition, that greatly can improve work top after adopting the present invention utilizes space.See the situation that the left side in accompanying drawing 2, figure is when being prior art use funnel, and the right is service condition of the present invention, as seen under same area, utilizes technology of the present invention to place and more filters vessel.
Claims (2)
1. the method for folding of a filter paper, comprise the steps: filter paper being folded into semicircle, again that semicircle is fan-shaped to being folded into right angle, its feature by filter paper to being folded into semicircle, again that semicircle is fan-shaped to being folded into right angle, again fan-shaped for right angle face is opened, along this right angle covering of the fan 1/2nd place to folding forming in paper.
2. the using method of a filter paper, it is characterized in that first carrying out folding forming by method according to claim 1 to filter paper, in the bottleneck again sharp corner of folding forming thing being inserted volumetric flask or conical flask or beaker mouth, the upper limb of folding forming thing is opened, directly carries out filtration operation.
