Summary of the invention
The object of this invention is to provide a kind of cell filter, for centrifuge tube or other body with the use of the filtration carrying out cell, easy to operate, complete processing is simple, and good to the protected effect of filter liquide, contaminated probability is little.
The present invention adopts following technical scheme: a kind of cell filter, comprises plastic filter body, and described plastic filter body comprises the cylindrical filtration cartridges surrounding filtering chamber and the filter membrane be arranged on described cylindrical filtration cartridges lower surface; The end face of described cylindrical filtration cartridges is provided with the edge of outside circumferential direction extension; described edge is arranged on the one end away from described filter membrane; the lower surface at described edge is provided with the screening glass be centered around outside cylindrical filtration cartridges; formed between described screening glass and described cylindrical filtration cartridges and protect chamber, the upper surface at described edge is provided with the clamping ring around described filtering chamber accent.
By implementing technique scheme, the liquid in filtering chamber is through membrane filtration, and the setting of screening glass can effectively prevent strainer from polluting the filter liquide of the inside because of contacting with other material; Clamping ring not only facilitates add liquid in filtering chamber, and can be coordinated with clamping ring by cylindrical filtration cartridges, and superposition uses strainer, carries out multiple times of filtration, strengthens filter effect, and the aperture of the filter membrane of different strainer can be different, set as required.
As preferably, the internal diameter of described clamping ring is greater than the diameter of described filtering 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 filtering chamber, is convenient to two and the superposition of above strainer, multi-filtering.
As preferably, the lower surface of described cylindrical filtration cartridges is provided with some back-up blocks, and when back-up block can be placed on the objects such as desktop at strainer, filter membrane does not contact desktop, preventing pollution; Again can when two and above strainer stack, can and clamping ring between form gap, prevent the space that formed between adjacent filter and ambient pressure inconsistent, cause filtration velocity to slow down.
As preferably, described cylindrical filtration cartridges is arranged some axial fins, described back-up block is extended by described axial fin and is formed, and strengthens the intensity of cylindrical filtration cartridges entirety, simplifies complete processing.
As preferably; the lower surface of described cylindrical filtration cartridges is lower than the lower surface of described screening glass, and in use, the lower surface rest of screening glass is on centrifuge tube; only have the bottom of cylindrical filtration cartridges to fall into centrifuge tube, prevent the liquid level in centrifuge tube too high and contact with filter membrane.
As preferably, described screening glass has an opening, is convenient to amount and the filtration situation of observing cylindrical filtration cartridges inner filtration liquid.
As preferably, described screening glass outside surface is provided with hand-held.
As preferably, described screening glass outside surface is provided with anti-skidding rib.
As preferably, the end face of described cylindrical filtration cartridges is provided with the supporting bar being positioned at the hydrophilic material below described filter membrane and making.Can not only prop up and hold filter membrane, protection filter membrane, and when causing liquid filtering slow owing to there is tension force between filter membrane and filter liquide, remove its tension force, liquid is easier to be flowed down along supporting bar.
By implementing technique scheme; strainer provided by the present invention and centrifuge tube or other body are with the use of the filtration carrying out cell; easy to operate; the complete processing of strainer is simple; multiple superposition can use, carry out multiple times of filtration, strengthen filter effect; good to the protected effect of filter liquide, contaminated probability is little.
