Abstract
The invention discloses a cell filtering device which comprises a filtering cylinder (1), wherein the opening end of the filtering cylinder (1) is provided with a brim (1), and the other end of the filtering cylinder (1) is shaped as a cone; and the filtering cylinder (1) comprises an annular brim inner ring (3), a support rod (4) and a filter membrane (5), wherein the support rod (4) is fixedly connected to a brim inner ring (3) and the filter membrane (5) is glued on the support rod (4). The invention has the advantages of simple structure and convenience for use. The filtering device can be effectively positioned on different liquid collecting containers due to the design of the brim so as to carry out experiment operation. A cell suspension or a mixture is directly injected to into the filtering device through the opening end, and cells can be filtered by means of the gravity, and therefore, the operation is convenient.
Description
Technical field
The present invention relates to a kind of filter, especially relate to a kind of filter of cell.
Background technology
At present, in biological medicine research, often be that model carries out in vitro study with the cell.In research process, regular meeting relates to screening, the separation of pair cell.Particularly when utilizing some instrument detecting,, need the cell that need detect be filtered for the accuracy that guarantees to detect and the security of instrument practicality.When using traditional cell filtration method and apparatus, need to shear filter membrane by hand, and after filter membrane is folded into funnel-form, be applied to filter.The filter operation process of using this device to carry out often needs multi agent cooperation, brings not convenient greatly to experiment.And filter in the market, volume ratio is bigger, can not with effective combination of other instruments in the experimentation, therefore use also extremely not conveniently, not only lose time and manpower, also easily cause experimental error.
Summary of the invention
In order to overcome the weak point of the prior art of above-mentioned indication, the invention provides a kind of simple in structure, easy to use, the cell filtration device of the firm gummed of bracing frame and filter membrane.
The present invention is achieved by the following technical solutions: a kind of cell filtration device, and described filter comprises filter cylinder, and the openend of described filter cylinder is provided with shade, and the other end is tapered; Encircle in the shade of this filter cylinder by annular, an end is fixed in the support bar on the ring in the shade and the filter membrane that is glued on the support bar constitutes.Described filter membrane is fitted and connected in shade and encircles.Described filter membrane bottom is conical.
Further, described filter membrane is the Fypro miillpore filter.
Further, described shade and support bar adopt stainless steel or plastic material.
The present invention is simple in structure, and is easy to use, and its shade design can make filter effectively be positioned at different connecing on the liquid container, carries out filter operation.The operator directly injects cell suspension or mixture from the filter openend, utilizes gravity effect pair cell to filter, and by the different big or small cells of the membrane filtration in different apertures, operation is convenient.
Description of drawings
Accompanying drawing 1 is a structural representation of the present invention;
Accompanying drawing 2 is a vertical view of the present invention.
Among the figure: 1-filter cylinder, ring in the 2-shade, 3-shade, 4-support bar, 5-filter membrane.
The specific embodiment
For the ease of those skilled in the art's understanding, the invention will be further described below in conjunction with accompanying drawing.
A kind of cell filtration device, shown in accompanying drawing 1,2, described filter comprises filter cylinder 1, and the openend of described filter cylinder 1 is provided with shade 2, and the other end is tapered; Encircle in the shade of this filter cylinder 1 by annular that 3, one ends are fixed in some support bars 4 on the ring 3 in the shade and the filter membrane 5 that is glued on the support bar 4 constitutes.It is conical that described filter membrane 5 bottoms are.Described filter membrane 5 is fitted and connected and encircles 3 in shade.Described some support bars 4 are arranged along ring in the shade 3.
Be evenly distributed with fenestra on the described filter membrane 5, film hole diameter is the 5-10 micron.Described filter membrane 5 is the Fypro miillpore filter.
Described shade 2 adopts stainless steel or plastic material, makes this filter be applicable to that difference connects liquid container by the size that designs shade 2, and it effectively is positioned on the related container of operating process, carries out filter operation.
Described support bar 4 adopts stainless steel or plastic material, plays fixedly filter membrane, and is solid by using specific glue and filter membrane 5 glue.
Utilize the present invention to carry out cell filtration when operation, this filter can be placed to connect in the liquid container, shade 2 is held on vessel port with the location, and cell suspension or mixture are directly at the uniform velocity injected filter from openend, and the effect pair cell by gravity filters.This filter can be used for filtering the cell of different sizes by the filter membrane that glues together different apertures.
The present invention can be used for the washing of cell, filters and enrichment etc., and by add liquid sample toward filter in, then cell to be collected is stayed on the filter membrane in the liquid, and other liquid pass and flow away after filter membrane leaches, thus the purpose that realization waits to collect cell enrichment.
The content of mentioning in the foregoing description is not to be limitation of the invention, and without departing from the inventive concept of the premise, any conspicuous replacement is all within protection scope of the present invention.
