Abstract
The utility model provides a clamping device for a dialysis bag. The clamping device for the dialysis bag comprises a dialysis clip and a magnet; an iron piece is arranged in a second clip piece; during dialysis, two ends of the dialysis bag are clamped by the dialysis clip, then the dialysis bag is placed in a container filled with a dialysis buffer solution, the magnet is placed outside the container, and the position of the dialysis clip is adjusted by regulating the position of the magnet according to the principle that the magnet attracts iron, so the position of the dialysis bag in the dialysis buffer solution is regulated to meet different experiment demands.
Description
Technical field
the utility model relates to medical experiment assistive device, a kind of clamping device for bag filter being specifically related to.
Background technology
In the preparation process of large biological molecule, often utilize dialysis to remove salt, organic solvent, the biological micromolecule impurity in sample.The bag filter using in dialysis procedure be by special-purpose pellicle per sample solution amount be folded into bag-shapedly accordingly, make with clip clamping at sack place.During dialysis, first large biological molecule sample solution is inserted in bag, then with immersing in water or buffer solution after clip clamping sack, the large biological molecule of the macromolecule in sample solution is trapped within bag, and the materials such as salt and little molecule constantly diffusion dialysis outside bag, until the concentration on the inside and outside both sides of bag reaches balance.
During dialysis, in order to accelerate dialysis speed, except repeatedly changing dislysate, also can use magneton to stir.But the clip using at present only comprises two intermediate plates and three parts of axle that are connected two intermediate plates, wherein, the other end of intermediate plate is provided with groove and the elastic projection that can be fastened and connected, after this clip clips on bag filter owing to not having buoyancy member can directly sink to bag filter the bottom of water or buffer solution, cause when dialysis, cannot use the mode of magnetic force rotor (the being designated hereinafter simply as magneton) stirring that can accelerate dialysis speed.
Application number is 201220436455.4 utility model patent, a kind of bag filter buoyancy folder that is provided with foam block is provided, can allow bag filter floating, but it is exposed on dialysis buffer liquid to cause part that the bag filter of dislysate is housed, and with the buoyancy folder of foam block, be difficult to carry out disinfection by thermophilic digestion etc., inapplicable for aseptic experiment of having relatively high expectations without RNA enzyme.
Summary of the invention
For addressing the above problem, the utility model provides a kind of adjustable dialysis bag at the medium-altitude bag filter clamping device of dislysate, adopts following technical scheme:
For a clamping device for bag filter, it is characterized in that comprising a dialysis clamp and a magnet; Described dialysis clamp comprises that the first intermediate plate, the second intermediate plate and the axle that is connected two intermediate plates, the other end of described the first intermediate plate are provided with elastic projection, the groove that the other end setting of described the second intermediate plate can be fastened and connected with described elastic projection; The inside of described the second intermediate plate arranges iron plate.
Further, described magnet is bar magnet.
The beneficial effects of the utility model are as follows:
1. the clamping device for bag filter that the utility model provides, comprise a dialysis clamp and a magnet, this device arranges iron plate in the inside of the second intermediate plate, when dialysis, with dialysis clamp, the two ends of bag filter are fixed, then put into glass or plastic containers that dialysis buffer liquid is housed, magnet is placed on to glass or plastic containers outside, according to magnetic iron principle, thereby according to experiment demand, by regulating magnet position, regulate the position of dialysis clamp, thereby regulate the position of bag filter in dialysis buffer liquid, to meet different experiments demand.
2. in the utility model, iron plate is arranged on to the inside of dialysis intermediate plate, avoids iron plate to contact with dialysis buffer liquid, thus corrosion iron plate.
Accompanying drawing explanation
Fig. 1 represents structural representation of the present utility model; Wherein 1 represents the first intermediate plate; 11 represent elastic projection; 12 represent groove; 13 represent iron plate; 2 represent axle; 3 represent magnet.
The specific embodiment
Below in conjunction with the specific embodiment, further set forth the utility model, but be not used in restriction scope of the present utility model.
As shown in Figure 1, a kind of clamping device for bag filter, is characterized in that comprising a dialysis clamp and a magnet 3; Described dialysis clamp comprises the first intermediate plate 1, the second intermediate plate and the axle 2 that is connected two intermediate plates, and the other end of described the first intermediate plate 1 is provided with elastic projection 11, the groove 12 that the other end setting of described the second intermediate plate can be fastened and connected with described elastic projection 11; The inside of described the second intermediate plate arranges iron plate 13.
Further, described magnet is bar magnet.
Using method of the present utility model is as follows:
With dialysis clamp provided by the invention by the closed at both ends of bag filter, then put into glass or plastic containers that dialysis buffer liquid is housed, magnet is placed on to glass or plastic containers outside, according to magnetic iron principle, according to experiment demand, thereby by the position of regulating magnet position adjusting dialysis clamp, thereby the position of bag filter in dialysis buffer liquid regulated, bag filter can be immersed in dialysis buffer liquid completely, but there will not be situation about sinking to the bottom.
Claims (2)
1. for a clamping device for bag filter, it is characterized in that comprising a dialysis clamp and a magnet; Described dialysis clamp comprises that the first intermediate plate, the second intermediate plate and the axle that is connected two intermediate plates, the other end of described the first intermediate plate are provided with elastic projection, the groove that the other end setting of described the second intermediate plate can be fastened and connected with described elastic projection; The inside of described the second intermediate plate arranges iron plate.
2. the clamping device for bag filter according to claim 1, described magnet is bar magnet.
