Abstract
The utility model discloses a simple and convenient liquid -transfering device, including the injection syringe, but be provided with the piston of back -and -forth movement in the injection syringe, the pipe of injection syringe is imported and exported and is connected with the sample tubule, is provided with filtration membrane between sample tubule and pipe are imported and exported, and through at syringe exit installation filtration membrane, the sample precipitates or the entering of residue in the time of can effectively preventing to inhale kind, guarantees to test the effect, also utilizes and protects detecting instrument, the sample tubule that adopts simultaneously is the flexible plastic pipe, and length is all adjustable, may not lie in splendid attire sample container's bore, degree of depth size direct sampling, and save time improves test efficiency, the utility model has the advantages of the practicality is strong, easy and simple to handle, can use widely in R&D institutions such as school, research institutes.
Description
Technical field
The utility model patent relates to a kind of easy liquid-transfering device, belongs to experiment equipment renovation technique field.
Background technology
At present, people are when carrying out lab analysis, and usually need to be transferred to by sample solution in different containers, different test equipment caliber size, the degree of depth are different; When shifting sample solution, we use pipette or liquid-transfering gun usually, but often because the container bore of splendid attire sample is too little or the degree of depth cannot well sample too greatly; Also or can sample but because sample early stage process time have precipitation or residue, and brought in next step analysis of experiments in the lump, such sample liquid transfer process too elapsed time and analysis of experiments is stressed results unsatisfactory, so existing liquid-transfering device is still perfect not
.
Summary of the invention
The purpose of this utility model is: provide a kind of structure simple, easy to operate, not only can facilitate pipette samples but also be unlikely to suck the easy liquid-transfering device of one of sample residue, to overcome the deficiencies in the prior art.
The utility model is achieved in that a kind of easy liquid-transfering device, comprises injection-tube, is provided with the piston that can move forward and backward in injection-tube, and the pipe of described injection-tube is imported and exported and is connected with sampling tubule, between sampling tubule and pipe are imported and exported, be provided with filter membrane.
Described filter membrane is nylon fine-structure mesh or gauze.
Injection-tube is provided with scale.
Owing to have employed technique scheme, compared with prior art, the utility model is by installing filter membrane at syringe outlet place, and when can effectively prevent from inhaling sample, sample pellet or the entering of residue, guarantee experiment effect, also utilizes protection detecting instrument; The sampling tubule simultaneously adopted is flexible plastic pipe, length is all adjustable, the bore of splendid attire shuttle, depth size direct sample can not minded, save time, improve test efficiency, the utility model has the advantages such as practical, easy and simple to handle, can promote the use of in the R&D institution such as school, research institute.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Description of reference numerals: 1-injection-tube, 2-piston, 3-filter membrane 4-samples tubule, and 5-pipe is imported and exported, 6-scale.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail, but not as to restriction of the present utility model.
Embodiment of the present utility model: a kind of easy liquid-transfering device, comprise injection-tube 1, in injection-tube 1, be provided with the piston 2 that can move forward and backward, the pipe of described injection-tube 1 is imported and exported 5 and is connected with sampling tubule 4, between sampling tubule 4 and pipe import and export 5, be provided with filter membrane 3.
Described filter membrane 3 is nylon fine-structure mesh or gauze.
Injection-tube 1 is provided with scale 6.
In the utility model, described injection-tube is plastic products, and described filter membrane is laboratory common materials nylon fine-structure mesh or gauze, and described sampling tubule is flexible plastic tubule.
The utility model filter membrane disassembling cleaning, very convenient, the adjustable length of sampling tubule, and container containing that the degree of depth larger less for bore, tubule is fairly obvious compared to the advantage of pipette or liquid-transfering gun.Structure of the present utility model is simple, it is extensive, easy to operate, time saving and energy saving to draw materials, and can promote the use of in the R&D institution such as school, research institute.
