Abstract
The utility model discloses a disposable microporous membrane filter. The disposable microporous membrane filter comprises an upper cup of which the upper part is open and the lower part is opened up and enclosed by a microporous membrane, and a receiving bottom which is positioned at the lower part of the upper cup, wherein a collector which is provided with a bleeder hole and is used for connecting the upper cup with the receiving bottle is arranged between the upper cup and the receiving bottle; and the receiving bottle is a polystyrene member. The receiving bottle is made from polystyrene, so that negative pressure produced by vacuumization in the bottle can be borne even when the volume of the receiving bottle is between 150 milliliters and 1,000 milliliters, experiment fluid can be filtered quickly, and the requirement on quick filtration of solution through the microporous membrane is met. The disposable microporous membrane filter has a simple structure, large volume and high intensity, is sterile internally, and is widely applied to fluid presettling, particle removal and aseptic filtration in life science laboratory or clinical experiments.
Description
Technical field
The utility model relates to the Filters that a kind of laboratory is used, particularly a kind of nuclepore membrane filter.
Background technology
When carrying out Biochemistry Experiment, to filter mixed solution usually, just need to use a kind of nuclepore membrane filter this moment.Nuclepore membrane filter generally comprises cup and is positioned at the receiving flask of its underpart, between the two every one deck micropore filtering film.Experimental Flowing Object is poured into after the cup, is filtered by micropore filtering film, and fine solid particle wherein and bacterium are promptly isolated, and filter back solution splashes into receiving flask.In order to raise the efficiency, point of attachment between last cup and receiving flask is provided with the connector with aspirating hole, after can being connected to aspirating hole by the vaccum-pumping equipment of peripheral hardware receiving flask is bled, make and form negative pressure in the receiving flask, accelerate the speed of filtrate, so this nuclepore membrane filter is called the vacuum type nuclepore membrane filter by micropore filtering film.Present vacuum type nuclepore membrane filter generally is to adopt stainless steel to make bottle, though have anticorrosion, advantage that structural strength is high, its cost height, reusable words have then been destroyed the requirement of some occasion to the cleanliness factor of solution.Some uses the disposable nuclepore membrane filter of plastic production bottle, though reduced production cost, realized disposable needs, but be usually designed to conical flask, reduced capacity in order to improve stability, if and be made into jumbo model, as 150ml to 1000ml, then can not bear and vacuumize formed negative pressure because structural strength is not enough, can only batch filtration, wasted equipment, the rate of filtration has slowed down.
The utility model content
The purpose of this utility model is for a kind of disposable nuclepore membrane filter is provided, and it has the characteristics of Experimental Flowing Object that can disposable filtering 150ml to 1000ml.
The solution that the utility model solves its technical problem is:
Disposable nuclepore membrane filter, comprise that opened upper end, bottom are got through and going up cup and being positioned at the receiving flask of its underpart with the miillpore filter sealing, described go up between cup and the receiving flask be provided with have aspirating hole, will go up the connector that cup and receiving flask link up, described receiving flask is a polystyrene component.
Be further used as preferred embodiment, described receiving flask integral body is the conical flask of tapering less than 3 degree.
Be further used as preferred embodiment, the described cup of going up all passes through sterilization treatment with receiving flask.
Be further used as preferred embodiment, described receiving flask body middle part indent, body is provided with scale to central concave at the bottle end.
Be further used as preferred embodiment, the capacity of described receiving flask is 150ml to 1000ml.
Be further used as preferred embodiment the described bowl cover 4 that also is provided with on the cup its upper opening sealing of going up.
The beneficial effects of the utility model are: the utility model utilizes the making material of polystyrene as receiving flask, even making its capacity is 150ml to 1000ml, also can bear the interior negative pressure of formed bottle when vacuumizing, the needs of the quick filtering with microporous membrane of solution have been satisfied in still can experimentize the apace filtration of fluid.
In addition, the utility model is designed to the slightly tapered shape that the bottom is bigger, bottle entad caves at the end with receiving flask, makes more reliable that the utility model places on experimental bench, and will bottle with cover during convenient the storage builds mutually and gather into folds, entad Ao Xian body also is easy to directly use holds.
The utility model is simple in structure, and capacity is big, and the intensity height is aseptic in the bottle, is widely used in the middle of the central fluid presettling of Life Science Experiment or clinical trial, particle-removing, the aseptic filtration.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described.
Fig. 1 is a cutaway view of the present utility model;
Fig. 2 is the explosive view of facing of the present utility model.
The specific embodiment
With reference to Fig. 1～Fig. 2, a kind of disposable nuclepore membrane filter, comprise that opened upper end, bottom are got through and going up cup 1 and being positioned at the receiving flask 2 of its underpart with the miillpore filter sealing, described go up between cup 1 and the receiving flask 2 be provided with have aspirating hole, will go up the connector 3 that cup 1 and receiving flask 2 link up, described receiving flask 2 is a polystyrene component.Wherein the type of miillpore filter can be MCE, nylon, PVDF and PES, and the micropore size scope is 0.1 μ m, 0.22 μ m, 0.45 μ m.
Be further used as preferred embodiment, described receiving flask 2 integral body are the conical flask of tapering less than 3 degree.This shape makes receiving flask 2 place more reliablely on the table, and liquid is difficult for spilling in the bottle.
Be further used as preferred embodiment, the described cup 1 of going up all passes through sterilization treatment with receiving flask 2.Particularly, be to utilize the gamma ray sterilization that carries out disinfection.
Be further used as preferred embodiment, described receiving flask 2 bodies middle part indent, body is provided with scale to central concave at the bottle end.This shape, with mutual of heap of stone the gathering into folds of bottle with cover, entad Ao Xian body also is easy to directly use holds during convenient the storage.
Be further used as preferred embodiment, the capacity of described receiving flask 2 is 150ml to 1000ml.
Be further used as preferred embodiment the described bowl cover 4 that also is provided with on the cup 1 its upper opening sealing of going up.
During use, earlier Experimental Flowing Object is poured in the cup 1, then the vaccum-pumping equipment of peripheral hardware is connected with the aspirating hole of connector 3 and bleed the interior negative pressure maximum of a control bottle year 6kg/cm
2, wait for that then solution filters, the scale above the receiving flask 2 when waiting solution to be filtered to the amount that needs, is closed vaccum-pumping equipment according to the observation, removes cup 1, can finish filtration.
More than be that preferable enforcement of the present utility model is specified, but the invention is not limited to described embodiment, those of ordinary skill in the art also can make all equivalent variations or replacement under the prerequisite of spirit of the present invention, modification that these are equal to or replacement all are included in the application's claim institute restricted portion.
