Specific embodiment
Fig. 1-Fig. 3 is referred to, this utility model is a kind of cell filter, and which includes generally columnar rack body
1, one end of rack body 1 is fixedly installed support apical ring 11, and the external diameter of support apical ring 11 is more than the external diameter of rack body 1；?
The other end (i.e. the other end of one end for being provided with support apical ring 11 of rack body 1) of frame body 1 is fixedly installed inclination
Drainage screen 12 (i.e. the inclination angle B of drainage screen 12 is more than zero degree)；Hydrophilic oxidant layer is provided with drainage screen 12.
A kind of operation principle of the cell filter in this utility model is：When needing using cell filter, by cell
In filter insertion test tube 2, cell suspension sample is added cell filter lentamente then.
As the other end of rack body 1 is fixedly installed the drainage screen 12 of inclination；Hydrophilizing agent is provided with drainage screen 12
Layer；Cell suspension sample can easily overcome surface tension, may pass through drainage screen 12 downstream to 2 bottom of test tube by gravity
Portion, and without the need for by being centrifuged-suspending again or realize filtering by other external force.
When cell suspension sample is all added in cell filter, and after the completion of cell suspension sample is all filtered, from
In test tube 2 extract out cell filter and as needed process cell filter (such as can by cell filter make rubbish abandon,
To can also reuse after cell filter cleaning and sterilizing).Cell suspension sample in test tube 2 then can be used for next step
Experiment, such as FCM analysis experiment.
It is, of course, also possible to applying positive air pressure into cell filter (is fixedly installed support apical ring from cell filter
The opening of 11 one end, applies air pressure to the direction towards drainage screen 12), to accelerate the rate of filtration.
Rack body 1 can also be fixedly installed support ring 13；Support ring 13 is arranged on the lower section of support apical ring 11.Will be thin
When born of the same parents' filter is taken out from test tube 2, finger can be put into space between support ring 13 and support apical ring 11, such that it is able to convenient
Cell filter is taken out from test tube 2 in ground.
The breach 15 for running through is also provided with support ring 13.Interior for test tube 2 and extraneous UNICOM can be entered one by breach 15
Step ground ensures 2 inner air flow of test tube, so that the cell suspension sample in rack body 1 more successfully can be filtered.
The outer wall of rack body 1 can also be fixedly installed at least three reinforcements 14.Three reinforcements 14 can be played
The effect of positioning, makes approximate closely (i.e. the outer wall of rack body 1 has gap with the inwall of the test tube 2) insertion of cell filter
Test tube 2, it is ensured that 2 inner air flow of test tube, so that the cell suspension sample in cell filter more successfully can be filtered,
And also cell filter can be made easily to be inserted or removed from test tube 2.
The section of reinforcement 14 can be triangle.The contact area of reinforcement 14 and 2 inwall of test tube can be reduced and subtracted
Less friction, so that cell filter can be more easily inserted into or remove test tube 2, easy to operate.
The outer wall of rack body 1 can be provided with color coating.By distinguishing different colors, easily can distinguish not
Filter with the drainage screen 12 in aperture；For example the cell filter of the corresponding 40um bore filters net 12 of red coatings, yellow are applied
The cell filter of the corresponding 75um drainage screens 12 of layer, the cell filter of the corresponding 100um drainage screens 12 of green coating；To adapt to not
The needs of same test tube 2 (for example FCM analysis pipe).
Rack body 1 can be made up of polystyrene or rustless steel.Rack body 1 is made for polystyrene, can be adopted
Sterilized with gamma sterilization, more convenient；Rack body 1 is made for rustless steel and can then adopt conventional laboratory high temperature height
Pressure sterilizing, reaches reusable purpose.
Drainage screen 12 can be made up of nylon or rustless steel.Drainage screen 12 is made for nylon and can then adopt gamma ray
Sterilization, more convenient；Drainage screen 12 is made for rustless steel and then can adopt conventional laboratory autoclave sterilization, reaches
Reusable purpose.
The inclination angle B of drainage screen 12 can be 30 degree or 45 degree or 60 degree.
It should be noted that those skilled in the art are easily derived according to above-described embodiment, the height of cell filter
(i.e. support apical ring 11 upper surface to the lowermost end of drainage screen 12 distance) be different numerical value embodiment, or drainage screen 12
Inclination angle B be other numerical value embodiment；In order to avoid unnecessary repetition, below repeat no more, but without departing from this practicality
New protection domain.
In sum, a kind of cell filter in this utility model, by gravity may pass through drainage screen 12 downstream to
2 bottom of test tube, and without the need for by being centrifuged-suspending again or realize filtering by other external force；Can ensure that air in test tube 2
Circulation, so that the cell suspension sample in cell filter more successfully can be filtered, and also can make cell filtration
Device is easily inserted or removed from test tube 2.
