Description
Technical field
The utility model is related to biological sample separation field, especially a kind of annular magnetic frame.
Background technology
Magnetic separation technique has a wide range of applications in biology field, and experimental subjects includes nucleic acid, protein
Etc. a large amount of biological samples.Compared with conventional method, the advantage of magnetic separation technique is mainly reflected in purification efficiency height, test period
It is short etc..Magnetic frame is the important component in magnetic separation technique, and adsorbability enrichment with magnetic bead that can be by is to holding
On the tube wall of device, you can realize the unadsorbed separated purpose of substance.Existing magnetic frame is not tight there is being bonded with container
Close, enrichment with magnetic bead efficiency is low, occupy lab space it is larger and for the versatility of different model container it is poor the shortcomings that.
Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art, provide a kind of structure novel, good separating effect, set
The high magnetic frame of standby versatility.
The utility model realizes that the technical solution of purpose is as follows：
A kind of annular magnetic frame for biological sample purification, including frame body and interchangeable adapter.Frame body lower part is
Bearing, top are operating space, annular magnet are inlaid on frame body top, the outermost circle of magnet is there are one inclined-plane, for being given birth to
Object Sample Purification on Single, frame body stretch out a pillar for fixed adapter from the ring in the middle part of magnet, and there have on pillar to be vertical
Card slot on groove, with adapter can be fixedly secured.Adapter has the different model for different model centrifuge tube.Adapter
Outside, which corresponds to magnet chamfered portion and is designed with the corresponding card slot of different model centrifuge tube, can be fixedly secured the centrifugation of various models
Pipe so that the lower part for centrifuging bottom of the tube is stretched out outside magnet, and the inclined-plane of top and magnet fits closely.
Meanwhile adapter enables to the top half of centrifugation bottom of the tube and magnet to fit closely, magnetic is stretched out in the latter half
It is not contacted outside iron with magnet.
Meanwhile a frame body can be mating with the progress of multiple adapters, to adapt to the requirement of different model centrifuge tube.
The beneficial effects of the utility model are：
When centrifuge tube is positioned on corresponding adapter, tube bottom top half and magnet fit closely, tube bottom lower half
Point stretch out outside magnet, enrichment with magnetic bead in pipe on tube body top, while tube body lower part without magnetic bead, facilitate unadsorbed portion
It separates.Each the opening there are one about half centimetre is stayed in the outer part of centrifuge tube card slot on adapter simultaneously, simultaneously
Entire adapter integrally uses milky material so that whether laboratory technician is enriched with completely convenient for observation magnetic bead.It is every on adapter
The diameter of the card slot of a centrifuge tube is slightly less than the diameter of centrifuge tube so that centrifuge tube can be firmly stood upright on adapter, no
It can arbitrarily rotate.
Magnetic frame stent lower part uses heavier material, and decorative pattern is carved in bottom surface so that magnetic frame can integrally consolidate vertical
On experiment table top.It can complete the conversion of sample room during experiment in itself by rotating magnetic frame.
Description of the drawings
Fig. 1 is the top view of the utility model, and Fig. 2 is rip cutting figure.Fig. 3 is the rip cutting figure after more changer adapter.
Specific embodiment
Below in conjunction with the accompanying drawings and pass through specific embodiment the utility model is described in further detail, following embodiment is simply retouched
The property stated, be not limited, it is impossible to limit the scope of protection of the utility model with this.
As shown in Figure 1, 2.A kind of annular magnetic frame for biological sample purification, including frame body 1 and interchangeable adaptation
Device 2.Frame body lower part is bearing, and top is operating space, and annular magnet 3 is inlaid on 1 top of frame body, and the circle of magnet 3 outermost one has one
A inclined-plane, for carrying out biological sample purification, frame body stretches out a pillar for fixed adapter from the ring at 3 middle part of magnet
4, there is vertical groove 5 on pillar, can be fixedly secured with the card slot on adapter 2.Adapter 2 have for different model from
The different model of heart pipe.Corresponding 3 chamfered portion of magnet in 2 outside of adapter is designed with the corresponding card slot 6 of different model centrifuge tube can
To be fixedly secured the centrifuge tube of various models so that the outside of magnet 3 is stretched out in the lower part for centrifuging bottom of the tube, top and magnet 3 it is oblique
Face fits closely.
Meanwhile adapter 2 enables to the top half of centrifugation bottom of the tube and magnet 3 to fit closely, the latter half is stretched out
It is not contacted outside magnet with magnet 3.
Meanwhile a frame body 1 can be carried out with multiple adapters 2 it is mating, with adapt to the use of different model centrifuge tube need
It asks.
When centrifuge tube is positioned on corresponding adapter 2, tube bottom top half and magnet fit closely, tube bottom lower half
Point stretch out outside magnet, enrichment with magnetic bead in pipe on tube body top, while tube body lower part without magnetic bead, facilitate unadsorbed portion
It separates.Each the opening there are one about half centimetre is stayed in the outer part of centrifuge tube card slot 6 on adapter 2 simultaneously, together
When entire adapter 2 is whole uses milky material so that whether laboratory technician is enriched with completely convenient for observation magnetic bead.Adapter 2
The diameter of the card slot 6 of upper each centrifuge tube is slightly less than the diameter of centrifuge tube so that centrifuge tube can firmly stand upright on adapter
On, it will not arbitrarily rotate.
1 lower part of magnetic frame frame body uses heavier material, and decorative pattern is carved in bottom surface so that magnetic frame can integrally consolidate vertical
On experiment table top.It can complete the conversion of sample room during experiment in itself by rotating magnetic frame.
The magnetic frame frame body 1 and adapter 2 are plastic construction, and 3 part of magnet is magnet, and wherein frame body lower part uses density
Larger material ensures the stabilization of entire frame body center of gravity.Adapter shares 2ml, 1.5ml, 0.5ml, 0.2ml totally four models,
It is used for the centrifuge tube of above four kinds of models.
Different adapters are due to consideration that will ensure the close contact of centrifuge tube bottom bevel and magnet 3, so centrifuge tube
Card slot 4 can be slightly tilted.Concrete condition is as shown in Figure 3.
Above to the better embodiment of the utility model, but the embodiment of the utility model is not limited to above-mentioned side
Formula.Any Spirit Essence without departing from the utility model under principle the change made, modification, replacement, combine, simplification etc.
For equivalent substitute mode, within the scope of protection of the utility model.
