Description
Technical field
The utility model belongs to Bioexperiment instrument field, is related to a kind of filter, and in particular to a kind of drawing and pulling type mistake
Filter device.
Background technology
As Protocols in Molecular Biology applies to the research of glacier microorganism, glacial snow and ice sample originally probably needs 1
L can just meet the 16S rRNA analyses of routine.But grand genome high throughput sequencing technologies of today, each sample at least need 10
L and it is necessary to must have repetition, this brings very big difficulty to a large amount of collections of glacial snow and ice sample.Filled with traditional filtering
An only filter screen is put, a filter membrane can only be once installed, in actual mechanical process, if there is dust particle in sample, just
Melt water can be prevented to continue toward dirty.200 ml of general filtering just need to change film.Carry out in the wild such operation very it is cumbersome not
Just, it is also easy to the pollution for causing filter membrane and filter cup during film is changed.
Utility model content
The utility model in the prior art, collects microorganism in glacier melting, existing Bioexperiment in the wild for solution
Sampling difficulty, the easily technical problem such as pollution, disclose a kind of drawing and pulling type filter.
To solve above-mentioned technical barrier, the utility model uses following technical scheme：
A kind of drawing and pulling type filter, including valve, screen pack, base and screen pipe, the screen pipe are cylindrical shape,
Screen pipe is provided with import and vacuum filtration mouth, and entrance is provided with valve；Be provided with the screen pipe flange, the first screen pack,
Second screen pack and the 3rd screen pack, the first screen pack, the second screen pack and the 3rd screen pack are funnel shaped, and first filters
Net, the second screen pack and the 3rd screen pack are separately fixed on flange；The flange is fixed on taking of being set on screen pipe pipe shaft
Sample door, sampling gate outside are provided with handle；The vacuum filtration mouth is located at screen pipe pipe shaft bottom, filters bottom of the tube and base phase
Even.
The filter is additionally provided with the pedestal supporting with base, and base has magnetic with pedestal.
The mesh number of the screen packs of mesh number ＜ the 3rd of the screen packs of mesh number ＜ second of first screen pack.
The beneficial effects of the utility model are：The utility model is tied by the way that flange is fixed on sampling gate when filtering
Shu Hou, sampling gate is opened, can directly be sampled from the screen pack being fixed on flange, carry out follow-up experiment, simplify open country
The program of outer sampling, farthest avoid the pollution changed in membrane process.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Wherein, 1- pedestals, 2- bases, 3- sampling gates, the screen packs of 4- the 3rd, 5- flanges, 6- handles, the screen packs of 7- second,
The screen packs of 8- first, 9- screen pipes, 10- valves, 11- imports, 12- vacuum filtration mouths.
Embodiment
A kind of drawing and pulling type filter, including valve 10, screen pack, base 2 and screen pipe 9, the screen pipe 9 are cylinder
Shape, screen pipe 9 are provided with import 11 and vacuum filtration mouth 12, valve 10 are provided with import 11；Method is provided with the screen pipe 9
Blue 5, first screen pack 8, the second screen pack 7 and the 3rd screen pack 4, the first screen pack 8, the second screen pack 7 and the 3rd screen pack 4
For funnel shaped, the first screen pack 8, the second screen pack 7 and the 3rd screen pack 4 are separately fixed on flange 5；The flange 5 is solid
The sampling gate 3 set on the pipe shaft of screen pipe 9 is scheduled on, the outside of sampling gate 3 is provided with handle 6；The vacuum filtration mouth 12 is positioned at filtering
The pipe shaft bottom of pipe 9, the bottom of screen pipe 9 is connected with base 2.
The filter is additionally provided with the pedestal 1 supporting with base 2, and base 2 has magnetic with pedestal 1.
The mesh number of the screen packs 4 of mesh number ＜ the 3rd of the second screen packs of mesh number ＜ 7 of first screen pack 8.
Application method of the present utility model is as follows：Vacuum filtration mouth 12 is connected with vavuum pump first, opens filter
Valve 10, by sample add screen pipe 9 in, then open vavuum pump, the liquid in sample filtered out, filter complete
Afterwards, sampling gate 3 is opened, takes out the first screen pack 8, the second screen pack 7 and the 3rd screen pack 4 respectively, loads sterile centrifugation tube, together
When add PBS, be put into refrigerator, bring back laboratory, you can for DNA extraction etc. work.
