This utility model adopts the following technical scheme that a kind of cell filter, and including plastic filter body, described plastic filter body includes the cylindrical filtration cartridges surrounding filter chamber and the filter membrane being arranged on described cylindrical filtration cartridges lower surface；The end face of described cylindrical filtration cartridges is provided with the edge that outside circumferencial direction extends; described edge is arranged far from one end of described filter membrane; the lower surface at described edge is provided with the screening glass being centered around outside cylindrical filtration cartridges; forming protection chamber between described screening glass and described cylindrical filtration cartridges, the upper surface at described edge is provided with the clamping ring around described filter chamber accent.
By implementing technique scheme, the liquid in filter chamber is through membrane filtration, and the setting of screening glass can effectively prevent filter from polluting the filtration liquid of the inside with other material because of contacting；Clamping ring not only facilitates addition liquid in filter chamber, and can be coordinated with clamping ring by cylindrical filtration cartridges, and superposition uses filter, carries out multiple times of filtration, strengthens filter effect, and the aperture of the filter membrane of different filters can be different, set as required.
As preferably, the internal diameter of described clamping ring is more than the diameter of described filter chamber, and the inner side of described clamping ring arranges spacing collar, and the diameter of described spacing collar is less than the diameter of described filter chamber, it is simple to two and above filter superposition, multi-filtering.
As preferably, the lower surface of described cylindrical filtration cartridges is provided with some bracers, and when a bracer can be placed on the objects such as desktop at filter, filter membrane does not contact desktop, prevents from polluting；Again can when two and above filter stack, can and clamping ring between formed gap, prevent between adjacent filter formed space inconsistent with ambient pressure, cause the rate of filtration to slow down.
As preferably, described cylindrical filtration cartridges arranging some axial fins, described bracer is extended by described axial fin and is formed, and strengthens the intensity that cylindrical filtration cartridges is overall, simplifies processing technique.
As preferably, the lower surface of described cylindrical filtration cartridges is less than the lower surface of described screening glass, and in use, the lower surface rest of screening glass is on centrifuge tube, and the only bottom of cylindrical filtration cartridges falls in centrifuge tube, prevents the liquid level in centrifuge tube too high and contacts with filter membrane.
As preferably, described screening glass has an opening, it is simple to observe amount and the situation of filtration of cylindrical filtration cartridges inner filtration liquid.
As preferably, described screening glass outer surface is provided with hand-held.
As preferably, described screening glass outer surface is provided with anti-skidding rib.
As preferably, the end face of described cylindrical filtration cartridges is provided with and is positioned at the supporting bar that the hydrophilic material below described filter membrane is made.Can not only prop up and hold filter membrane, protect filter membrane, and in the case of causing liquid to filter slowly owing to there is tension force between filter membrane and filtration liquid, release its tension force, liquid is easier to flow down along supporting bar.
By implementing technique scheme; filter provided by the utility model and centrifuge tube or other body are with the use of the filtration carrying out cell; easy to operate; the processing technique of filter is simple; can use with multiple superpositions, carry out multiple times of filtration, strengthen filter effect; good to the protected effect filtering liquid, contaminated probability is little.
