Abstract
The utility model relates to a filter device for use in a laboratory, which can effectively solve the problems of increasing experiment efficiency, guaranteeing product yield rate, achieving convenient use with firm and durable property and low cost, and meeting the filtration experiment requirement, and the technical scheme of the filter device is that the filter device comprises a transparent hopper and a piece of filter paper; a glass network smelted with the transparent hopper into one body is transversely arranged at the middle-lower part in the transparent hopper; the cup-shaped filter paper is placed on the glass network; the lower end of the neck of the transparent hopper is inclined and opened. The filter device for use in the laboratory is simple and unique in structure, convenient in use, firm and durable and wide in use, effectively applicable to scientific research and laboratory teaching.
Description
Technical field
The utility model relates to experimental facilities, and filter is used in particularly a kind of laboratory.
Background technology
In scientific research and teaching Process of experiment, the filtration experiment operation is one of main experiment content in laboratory student experimenting and the scientific research process.The filtration experiment device that use always in the laboratory comprises: glass funnel, folded filter paper two parts.Wherein glass funnel is a laboratory laboratory apparatus commonly used, also is the major part of filtration experiment device.Filter paper is close to the hopper walls inwall in filter process, and the rate of filtration is very slow; Have more after folded filter paper is tapered two-layer can absorption portion solution and influence productive rate; Be prone to break in the folded filter paper process and cause filtration experiment failure, can be lower through filtering productive rate repeatedly.
Develop so a kind ofly can improve conventional efficient, ensure product yield, experimental provision easy to use, durable, cheap, that satisfy the filtration experiment demand is the technical problem that needs to be resolved hurrily.
Summary of the invention
To above-mentioned situation; For overcoming the defective of prior art; The purpose of the utility model just provides a kind of laboratory and uses filter, can effectively solve improve conventional efficient, ensure product yield, easy to use, durable, cheap, the problem that satisfies the filtration experiment demand.
The technical scheme that the utility model solves is, comprises transparent funnel and filter paper, and in the transparent funnel laterally there being and the molten all-in-one-piece glass web of transparent funnel the middle and lower part, is placed with cup-shaped filter paper above the glass web, and the bucket neck lower end of transparent funnel is the inclined-plane opening.
The utility model is simple in structure, and is novel unique, easy to use, durable, of many uses, can be effective to scientific research and laboratory teaching.
Description of drawings
Fig. 1 is structure (section) front view of the utility model.
Fig. 2 is the transparent funnel three-dimensional structure diagram of the utility model.
Fig. 3 is the cup-shaped filter paper three-dimensional structure diagram of the utility model.
The specific embodiment
Elaborate below in conjunction with the specific embodiment of accompanying drawing to the utility model.
Shown in Fig. 1-3, the utility model comprises transparent funnel and filter paper, and in the transparent funnel 1 laterally there being and the molten all-in-one-piece glass web 3 of transparent funnel the middle and lower part, is placed with cup-shaped filter paper 2 above the glass web, and bucket neck 4 lower ends of transparent funnel are inclined-plane opening 5.
In order to guarantee result of use, described cup-shaped filter paper 2 is suitable for reading to be lower than the suitable for reading of transparent funnel 1, overflows to prevent filtrating; Described transparent funnel 1 is the little taper shape in big bottom, top with cup-shaped filter paper 2, and is gapped slightly between the inwall of cup-shaped filter paper outer wall and transparent funnel.
The utlity model has following outstanding characteristics:
1, the utility model has saved the operation of folded filter paper, is placed on cup-shaped filter paper in the funnel, just can filter, and is easy to operate simple.
2, the transparent funnel of the utility model band net is inverted the adsorbent equipment that can be used as toxic gas, and the glass web in the funnel can be even with gas dispersion, helps the abundant absorption of gas.
3, the transparent funnel of the utility model band net is installed in and can be used as Bush's funnel on the bottle,suction and carry out decompress filter operation.
4, cup-shaped filter paper has solved the folded filter paper part problem that too much absorption is filtrated and filter paper is rolled over brokenly.
5, cup-shaped filter paper is placed on and has solved the slow problem of the rate of filtration on the glass web.
Claims (3)
