Abstract
The utility model discloses an aseptic detection film filtration device, be equipped with the filter membrane in strain a section of thick bamboo, straining a section of thick bamboo, as the improvement, the section of thick bamboo of straining lie in filter membrane top and be equipped with directly to advance the pipeline and filter the pipeline, the filtration pipeline be equipped with and filter, the filtration piece filter the aperture and be greater than the filter membrane and filter the aperture. The utility model discloses it sets up the filtration pipeline and directly advances the pipeline to lie in the filter membrane top on straining a section of thick bamboo. Through filtering the pipeline, the insoluble granule in the sample can be held back to the thicker filtration piece in aperture during filterable sample, with its enrichment in the filtration piece that filters the pipeline, avoid insoluble granule to float the influence to microbial cultivation, and air and liquid microorganism all can pass through, washing of this culture plate does not have the difference with ordinary culture plate after sample filtration completion. The pipeline is direct to be added through directly advancing to add the culture medium, can remain culture medium active ingredient, avoids active ingredient to be held back by thicker filter.
Description
Technical field
This utility model relates to a kind of limit test of microbe membrane filtration device, particularly coordinates the sterility test membrane filtration device that germ collector uses.
Background technology
Microbial limit test of drugs generally adopts membrane-filter procedure or direct inoculation, by observing colony growth point note micro organism quantity. But containing insoluble particles in Some Drugs, membrane filtration granule can block filter membrane and cause filtration difficulty, and no matter direct inoculation cannot get rid of the granule interference to result.
Summary of the invention
This utility model is for solving the problems referred to above, it is provided that a kind of limit test of microbe defecator, it is achieved the eliminating of granule is not retained microorganism to get rid of the granule interference to cultivation results.
This utility model solves the technical scheme of existing issue: a kind of limit test of microbe membrane filtration device, including membrane filter, described membrane filter is provided with air filtering assembly, inlet, leakage fluid dram, it is provided with microporous filter membrane in described membrane filter, as improvement, described membrane filter includes the upper shell and the end cylinder that are tightly connected, described air filtering assembly, inlet is arranged on upper shell, described leakage fluid dram is arranged on end cylinder, described microporous filter membrane is arranged at the intersection of upper shell and end cylinder, it is provided with prefilter between described air filtering assembly and inlet and microporous filter membrane, described prefilter pore size filter is more than filtering with microporous membrane aperture.
As further improvement, between described upper shell and end cylinder, it is provided with sealing ring.
As further improvement, described membrane filter also includes the connection lid of a locking upper shell and end cylinder.
This utility model is compared with prior art, it provides the benefit that membrane filter is arranged to the upper shell being tightly connected, end cylinder, microporous filter membrane is arranged at the intersection of upper shell and end cylinder, and the prefilter that pore size filter is bigger is set between air filtering assembly and inlet and microporous filter membrane, the prefilter that during sample filtered, pore size filter is bigger can retain the insoluble particles in sample, it is enriched in the prefilter of filter pipeline, avoid the floating impact on microorganism culturing of insoluble particles, and air and liquid microbe all can pass through, the flushing of this incubator and Nostoc commune Vanch device indistinction after sample filtering completes.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Referring to Fig. 1, the implementation case includes membrane filter 1, and membrane filter 1 is provided with air filtering assembly 2, inlet 3, leakage fluid dram 4, is provided with microporous filter membrane 11 in membrane filter 1.
Membrane filter 1 includes the upper shell 5 and the end cylinder 6 that are tightly connected, air filtering assembly 2, inlet 3 are arranged on upper shell 5, leakage fluid dram 3 is arranged on end cylinder 5, microporous filter membrane 11 is arranged at the intersection of upper shell 5 and end cylinder 6, being provided with prefilter 12 between air filtering assembly 2 and inlet 3 and microporous filter membrane 11, prefilter 12 pore size filter is more than microporous filter membrane 11 pore size filter. Such sample liquid and air enter membrane filter 1 from inlet 3, air filtering assembly 2 respectively, in, prefilter 12 first filters thicker insoluble particles successively, then through microporous filter membrane 11.
Being provided with sealing ring between upper shell 5 and end cylinder 6, membrane filter 1 also includes the connection lid 7 of a locking upper shell 5 and end cylinder 6, is provided with sealing ring along with the locking being connected lid 7, can improve tightness between upper shell 5 with end cylinder 6.
