Abstract
The utility model relates to a cell filtration device, comprising a filter cartridge (1), a brim (2) is arranged at the opening end of the filter cartridge (1) and the other end of the filter cartridge (1) is tapered; the filter cartridge (1) consists of a ring-shaped brim inner ring (3), a supporting rod (4) fixedly connected on the brim inner ring (3) and a filter membrane (5) glued on the supporting rod (4). The cell filtration device is simple in structure and is convenient to use, the filter device can be effectively located on different liquid receiving containers owning to the design of the brim, so as to carry out experimental operation. Cell suspension or mixture is directly injected into the filtration device through the opening end, and the cells can be filtered by utilizing the gravity function, so that the operation is convenient.
Description
Technical field
The utility model relates to a kind of filtration unit, especially relates to a kind of filtration unit 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 filtration unit.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, it is a kind of simple in structure, easy to use that the utility model provides, the cell filtration device of the firm gummed of bracing frame and filter membrane.
The utility model is achieved through the following technical solutions: a kind of cell filtration device, and described filtration unit comprises filter cylinder, and the opening end of described filter cylinder is provided with shade, and the other end is tapered; This filter cylinder is by encircling in the annular shade, and 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 tynex millipore filtration.
Further, described shade and support bar adopt stainless steel or plastic material.
The utility model is simple in structure, and is easy to use, and its shade design can make filtration unit effectively be positioned at different connecing on the liquid container, carries out filter operation.The operator directly injects cell suspension or mixture from the filtration unit opening end, utilizes the action of gravity 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 utility model;
Accompanying drawing 2 is a vertical view of the present utility model.
Among the figure: 1-filter cylinder, ring in the 2-shade, 3-shade, 4-support bar, 5-filter membrane.
Embodiment
For the ease of those skilled in the art's understanding, the utility model will be further described below in conjunction with accompanying drawing.
A kind of cell filtration device, shown in accompanying drawing 1,2, described filtration unit comprises filter cylinder 1, and the opening end of described filter cylinder 1 is provided with shade 2, and the other end is tapered; 3, one ends are fixed in some support bars 4 on the ring 3 in the shade to this filter cylinder 1 and the filter membrane 5 that is glued on the support bar 4 constitutes by encircling in the annular shade.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 tynex millipore filtration.
Described shade 2 adopts stainless steel or plastic material, makes this filtration unit 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.
When utilizing the utility model to carry out the cell filtration operation, this filtration unit can be placed and 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 filtration unit from opening end, and the effect pair cell by gravity filters.This filtration unit can be used for filtering the cell of different sizes by the filter membrane that glues together different apertures.
The utility model can be used for the washing of cell, filters and enrichment etc., and by add liquid sample toward filtration unit 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 to qualification of the present utility model, and under the prerequisite that does not break away from the utility model design, any conspicuous replacement is all within protection domain of the present utility model.
