The coated filter screen in skeleton bottom, plastic skeleton and the coated shirt rim of filter screen, these parts are collectively forming the circle of a upper opening
Cylindrical cavity, the cavity of cylinder is put into test tube in the convex eaves position setting handle of the upper part of cylindrical cavity, use, on
Partial convex eaves is placed on test tube mouth as branch, and the culture medium containing cell is added into cylindrical empty intracavitary, carries out cell filtration.
But the cell filter the defects of uses in the presence of some：First, the shirt rim of cell filter and the gap for centrifuging tube edges are smaller,
Filtrate the shirt rim of easy filter by suction and forms fluid-tight in the presence of surface tension with the inwall of centrifuge tube so that in centrifuge tube
Malleation is formed, cell culture medium smooth can not circulate；2nd, cell filter and centrifuge tube are endless hermetically sealed, and filtrate passes through siphon
At the top of phenomenon suck-back to centrifuge tube, contacted with the outer surface at centrifuge tube top and cell filter, easily cause pollution；3rd, cell
The shirt rim of filter is smaller with the gap for centrifuging tube edges and handle and the convex eaves of annular operate in same level, cell filtration
When, finger grips said handle is tilted over the inconvenient for operation of filter；4th, when superclean bench operates, air-flow is to flow from top to bottom
Dynamic, when hand-held cell filter is operated, air-flow easily brings the pollutant on hand or on rubber gloves in centrifuge tube into, makes
Into the pollution of culture cell, harmful effect is produced to experimental result.
Utility model content
To solve the above problems, the utility model provides a kind of centrifuge tube for preventing that generation malleation, pollution are small in centrifuge tube
The cell filter of formula.
Technical scheme is used by the utility model solves its technical problem：
A kind of cell filter for centrifuging tubular type, including lid, upper tube body and the lower tube body of removable seal connection successively,
Air-vent is provided with lower tube body, hydrophobic filter membrane is provided with air-vent, filter is provided with upper tube body and lower tube body junction,
Filter is set in back taper.
As the further improvement of above-mentioned technical proposal, filter includes taper framework and the filter being laid in taper framework
Net, taper framework include some connecting plates of upper annulus, lower annulus and the upper annulus of connection and lower annulus, and the radius of upper annulus is more than
The radius of lower annulus.
As the further improvement of above-mentioned technical proposal, upper annulus side is provided with convex with the mating connection of lower tube body upper end
Ring.
As the further improvement of above-mentioned technical proposal, the bottom of air-vent and the bottom of filter are located at same level
On.
As the further improvement of above-mentioned technical proposal, non-slip texture is provided with lid.
It is threaded connection between lid, upper tube body and lower tube body as the further improvement of above-mentioned technical proposal.
The beneficial effects of the utility model：The cell filter of this centrifugation tubular type is set by air-vent and filter,
After filtrate enters, because filter is back taper, there is certain angle, it is therefore prevented that filtrate between filter outer wall and lower tube body inwall
Accumulation forms fluid-tight between filter and lower tube body, and the setting of air-vent avoids forming malleation in lower tube body, enables filtrate smooth
By the way that lid, the sealed connection of upper tube body and lower tube body and the setting of hydrophobic filter membrane avoid external air flow from bringing pollutant into, carry
High experimental precision.
Brief description of the drawings
The utility model is described in further detail below in conjunction with the accompanying drawings：
Fig. 1 is the overall structure of the explosion figure for the cell filter for centrifuging tubular type；
Fig. 2 is the filter structure schematic representation for the cell filter for centrifuging tubular type.
Embodiment
Referring to Figures 1 and 2, the utility model is a kind of cell filter for centrifuging tubular type, including removable seal successively
