Description
Technical field
This utility model relates to fluid sample filtration art, especially relates to a kind of micro-example defecator.
Background technology
Either it is frequently necessary to when carrying out chemical experiment or biotic experiment carry out filtering this experimental implementation to obtain target product.Traditional filter type is to use filter paper to be placed in buchner funnel to filter.But for the filtration of micro-example, traditional filter type clearly cannot meet requirement of experiment.As can be seen here, a kind of micro-example defecator how is worked out, it is possible to the filtration making micro-example is simpler, quick, is current those skilled in the art's problem demanding prompt solution.
Summary of the invention
In order to solve the problems referred to above, this utility model provides a kind of micro-example defecator being easy to micro-example filtration.
This utility model one micro-example defecator includes filter paper, injector syringe and be positioned at the syringe piston within described injector syringe, described filter paper is built in filter paper bottom and fixes in container, the filter paper top layer that is also arranged above of described filter paper fixes container, described filter paper bottom is fixed container and described filter paper top layer and is fixed container and be interlocked and make described filter paper be fixed, the upper surface that described filter paper top layer fixes container is provided with the pipe of projection, it is placed in described pipe in the syringe needle of described injector syringe, it is additionally provided with retaining collar between described pipe and described syringe needle, the lower surface that container fixed by described filter paper bottom is provided with for discharging the outlet filtering liquid.
Further, described injector syringe is 1mL injector syringe, and described syringe piston is 1mL syringe piston.
Further, the material of described retaining collar is elastomeric material.
Further, the cross-sectional area of described filter paper fixes the cross-sectional area of container more than described filter paper top layer.
Further, container fixed by described filter paper bottom is filtration funnel.
This utility model one micro-example defecator, compared with prior art has the advantage that
First, this micro-example defecator fixes container by described filter paper top layer fix container with described filter paper bottom and be interlocked, thus described filter paper is fixed on described filter paper top layer firmly fixes container and described filter paper bottom is fixed between container, effectively prevent from hindering being normally carried out of filtration because fold occurs at filter paper described in filter process；In addition, owing to sample to be filtered is micro-example, carrying out filtering the most difficult so relying solely on gravity, this design holds micro-example to be filtered by utilizing injector syringe, utilize syringe piston boosting, so that described micro-example is rapidly completed filter process.This design makes the filter process of micro-example the simplest, quick, improves filter efficiency.
Second, described in this micro-example defecator, injector syringe is 1mL injector syringe, and described syringe piston is 1mL syringe piston.Why select the described injector syringe of this model and described syringe piston primarily to match with the volume of micro-example, the boosting power making micro-example suffered when filtering on described filter paper is bigger and longer by the time of described boosting power, and the most described micro-example filter process is implemented smoothly.
3rd, described in this micro-example defecator, the material of retaining collar is elastomeric material.Why use elastomeric material to prepare described retaining collar primarily to make described retaining collar preferably lock described syringe needle and described pipe, prevent, when fixing container injection micro-example to described filter paper top layer, the phenomenon that described syringe needle is separated with described pipe occurs.

Detailed description of the invention
In order to be better understood from this utility model, below in conjunction with specific embodiments and the drawings, this utility model is conducted further description.
As shown in Figure 1, a kind of micro-example defecator includes filter paper 5, injector syringe 2 and be positioned at the syringe piston 1 within described injector syringe 2, described filter paper 5 is built in filter paper bottom and fixes in container 6, the filter paper top layer that is also arranged above of described filter paper 5 fixes container 4, described filter paper bottom is fixed container 6 and described filter paper top layer and is fixed container 4 and be interlocked and make described filter paper 5 be fixed, the upper surface that described filter paper top layer fixes container 4 is provided with the pipe of projection, it is placed in described pipe in the syringe needle of described injector syringe 2, retaining collar 3 it is additionally provided with between described pipe and described syringe needle, the lower surface that container 6 fixed by described filter paper bottom is provided with for discharging the outlet filtering liquid.
This design is fixed container 4 by described filter paper top layer and is fixed container 6 with described filter paper bottom and be interlocked, thus described filter paper 5 is fixed on described filter paper top layer firmly fixes container 4 and described filter paper bottom is fixed between container 6, effectively prevent from hindering being normally carried out of filtration because fold occurs at filter paper 5 described in filter process.In addition, owing to sample to be filtered is micro-example, carrying out filtering the most difficult so relying solely on gravity, this design holds micro-example to be filtered by utilizing injector syringe 2, utilize syringe piston 1 boosting, so that described micro-example is rapidly completed filter process.This design makes the filter process of micro-example the simplest, quick, improves filter efficiency.
Described injector syringe 2 is 1mL injector syringe, and described syringe piston 1 is 1mL syringe piston.Why select the described injector syringe 2 of this model and described syringe piston 1 primarily to match with the volume of micro-example, the boosting power making micro-example suffered when filtering on described filter paper 5 is bigger and longer by the time of described boosting power, and the most described micro-example filter process is implemented smoothly.
The material of described retaining collar 3 is elastomeric material, such as polyurethane rubber etc..Why use elastomeric material to prepare described retaining collar 3 primarily to make described retaining collar 3 preferably lock described syringe needle and described pipe, prevent the phenomenon that described syringe needle is separated with described pipe occurring fixing when micro-example injected by container 4 to described filter paper top layer.
Fix to make described filter paper 5 more successfully be fixed container 4 by described filter paper top layer, so the cross-sectional area of described filter paper 5 is designed as fixing more than described filter paper top layer the cross-sectional area of container 4.The most described filter paper top layer is fixed container 4 and is easy to be pressed in the edge of described filter paper 5, makes described filter paper 5 be fixed.
In order to make the filtrate of described micro-example flow out smoothly, so the described filter paper bottom in the present embodiment is fixed container 6 and used the funnel filtered.So on the one hand, on the other hand the manufacturing cost of saver is inverted cone-shaped due to funnel so the outflow of more convenient filtrate.
Above embodiment of the present utility model is described in detail, but described content has been only preferred embodiment of the present utility model, it is impossible to be considered for limiting practical range of the present utility model.All impartial changes made according to this utility model scope and improvement etc., within all should still belonging to this patent covering scope.
