Abstract
The utility model discloses a kind of Sterility testing membrane filtration device, comprise filter cylinder, be provided with filter membrane in filter cylinder, as improvement, described filter cylinder is positioned at above filter membrane and is provided with deep bed filter, and described deep bed filter pore size filter is greater than membrane filtration aperture.The utility model is positioned at above filter membrane and arranges deep bed filter on filter cylinder, the thicker deep bed filter in aperture can retain the insoluble particles in sample, avoid the impact that insoluble particles is cultivated microorganism, and air and liquid microbe all can pass through, the flushing of this incubator and Nostoc commune Vanch device indistinction after sample filtering completes.Culture medium active ingredient can be retained, avoid active ingredient to be retained by thicker filter.Deep bed filter significantly increases the filtration total throughput of filter liquide.
Description
Technical field
The utility model relates to a kind of sterility test membrane filtration device, particularly coordinates the sterility test membrane filtration device that germ collector uses.
Background technology
Pharmaceutical sterile test adopts membrane-filter procedure or direct inoculation usually, judges whether to occur microorganism by the turbidity change observing culture medium.But cannot, by the particulate of membrane filtration, membrane-filter procedure cannot be carried out containing naked eyes are invisible in Some Drugs.
Summary of the invention
The utility model, for solving the problem, provides a kind of sterility test filter avoiding insoluble particles interference detection results.
The technical scheme that the utility model solves existing issue is: a kind of Sterility testing membrane filtration device, comprise filter cylinder, in filter cylinder, be provided with filter membrane, as improvement, described filter cylinder is positioned at above filter membrane and is provided with deep bed filter, and described deep bed filter pore size filter is greater than membrane filtration aperture.
As further improvement, described filter cylinder is provided with inlet.
As further improvement, described filter cylinder still there is air filtering assembly.
The utility model compared with prior art, its beneficial effect is positioned at above filter membrane to arrange deep bed filter on filter cylinder, the thicker deep bed filter in aperture can retain the insoluble particles in sample, avoid the impact that insoluble particles is cultivated microorganism, and air and liquid microbe all can pass through, the flushing of this incubator and Nostoc commune Vanch device indistinction after sample filtering completes.Culture medium active ingredient can be retained, avoid active ingredient to be retained by thicker filter.Deep bed filter significantly increases the filtration total throughput of filter liquide.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
See Fig. 1, the implementation case comprises filter cylinder 1, filter cylinder is provided with inlet 11 and air filtering assembly 12, filter membrane 2 is provided with in filter cylinder 1, filter cylinder 1 is positioned at above filter membrane 2 and is provided with deep bed filter 3, deep bed filter 3 pore size filter is greater than filter membrane 2 pore size filter so that filter out can block filter membrane do not allow particle, secondly deep bed filter 3 significantly increases the total throughput of filter liquide.
Claims (2)
1. a Sterility testing membrane filtration device, comprise filter cylinder, in filter cylinder, be provided with filter membrane, it is characterized in that: described filter cylinder is provided with inlet, described filter cylinder is positioned at above filter membrane and is provided with deep bed filter, and described deep bed filter pore size filter is greater than membrane filtration aperture.
2. Sterility testing membrane filtration device as claimed in claim 1, is characterized in that: described filter cylinder still has air filtering assembly.
