Abstract

The utility model relates to a millipore valve drop tube, which comprises a drop tube vitreous body and a glue head, and a millipore valve is arranged between the drop tube vitreous body and the glue head. The utility model has the advantages of simple structure and convenient operation, etc., has obvious effect on preventing the glue head from being corroded, prolongs the service life of the glue head, prevents effectively the phenomenon that the chemical agent which flows into the glue head from the drop tube is caused by the operate miss, and is suitable for the replaced use of all drop tubes.

Description

Micropore valve dropper
The utility model relates to a kind of dropper.
Dropper is an indispensable instrument of drawing chemical reagent in the chemical test.Present dropper is made of vitreum and glue head, between directly be communicated with, do not intercept.In the experimental implementation process, often lack of standardization because of operating, make mordant reagent enter dropper glue head easily, thereby it is aging to quicken the corrosion of glue head, influence the serviceable life of glue head.
The purpose of this utility model is the shortcoming that overcomes above-mentioned prior art, and a kind of micropore valve dropper is provided, and it allows pressure gas freely to come in and go out, and liquid then can not be by having avoided the corrosion of glue head.
The technical solution of the utility model is: a kind of micropore valve dropper, comprise dropper vitreum and glue head, and it is characterized in that between dropper vitreum and the glue head micropore valve being arranged.
The utlity model has simple in structure, easy to use, characteristics such as antiseptic effect is remarkable, owing in traditional dropper vitreum afterbody, designed very simple micropore valve, this valve allows pressure gas freely to come in and go out, liquid then self surface tension and the glue head in can not freely pass through under the acting in conjunction of gas, so prevented in the operating process keeping flat or being inverted and cause the reagent to flow into the phenomenon of glue head by dropper effectively because of dropper, thereby avoided the experimenter to quicken the aging phenomenon of glue head corrosion because of operation causes reagent to enter the glue head in violation of rules and regulations, prolonged the serviceable life of glue head, also simplifying simultaneously and alleviated operation and the labour intensity that cleans dropper, is the renewal product of all traditional droppers.
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is a synoptic diagram of the present utility model.
Embodiment 1: as shown in Figure 1, the utility model is made up of dropper vitreum 1 and glue head 2, it is characterized in that being provided with micropore valve 3 between dropper vitreum 1 and glue head 2.Liquid in pipe can not enter the glue head after installing the micropore valve additional, and gas can freely be come in and gone out.
