Abstract
The utility model provides a magnetic separation tool suitable for magnetic bead method extraction of DNA or magnetic bead method purification of proteins, belonging to the field of magnetic separation devices. The magnetic separation tool comprises a base and a main frame, wherein a permanent magnet is arranged in the base; the main frame is connected with the base via four struts; strip elastic mechanisms are uniformly arranged in the transverse direction and the longitudinal direction of the crossbeam of the main frame, respectively. The magnetic separation tool provided by the utility model is especially suitable for magnetic separation of a large amount of centrifuge tubes (volume larger than 50 mL), cell culture flasks and the like, and has fixing effect on the to-be-separated centrifuge tubes, culture flasks, and the like.
Description
Technical field
The utility model relates to magnetic separating device, and particularly a kind of applicable paramagnetic particle method extracts the magnetic resolution instrument of DNA or paramagnetic particle method purifying protein.
Background technology
The application of magnetic separation technique in cytobiology, immunology, therapeutics, diagnostics and pharmacy etc. separation is more and more extensive, for example protein and enzyme fixing, immunoassay, the purifying of RNA and DNA, cellular segregation and pharmaceutical carrier etc.Compare as the precipitator method, centrifuging, ion exchange method and various chromatography methods with conventional separation method, that magnetic separation technique has is convenient and swift, required equipment is simple, velocity of separation is fast, extraction efficiency high, be conducive to keep the advantages such as properties of samples, particularly biological activity.
Magnetic separator frame is a kind of magnetic separating apparatus simple in structure, easy to use.During use, the centrifuge tube that sample is housed is put into magnet stand hole, the magneticsubstance in sample can be enriched in the tube wall near magnetic separator frame pillar one side, then with pipettor, liquid is siphoned away and can realize the separation of magneticsubstance from solution.The biological magnetic separation technique of nanometer magnetic bead needs by strong magnetic the cell with magnetic mark or biological adsorption in application.
Existing various types of magnetic separation rack generally only can support centrifuge tube, fails fixing centrifuge tube.In use, if need to overturn multiple centrifuge tubes, can make centrifuge tube drop, operate very inconvenient.Some magnetic separation racks, for fixing centrifuge tube, are set as support hole and centrifuge tube shrink-fit, require great effort very much, and the wearing and tearing of magnetic separation rack are also very serious but such design makes to plug centrifuge tube.
Existing commercially available various types of magnetic separator majorities are for the centrifuge tube design below 10mL, but in some cases, as Magnetic cell sorting process, directly use Tissue Culture Flask more favourable as the container of material to be separated, on the one hand without changing centrifuge tube, can effectively expand on the other hand the contact area containing container and the magnetic spacer plate of material to be separated, be conducive to the sharp separation of a large amount of magnetic particles.
Therefore, design a kind of above centrifuge tube of 50mL, Tissue Culture Flask etc. of being applicable to and carry out a large amount of magnetic resolution, and to centrifuge tube to be separated, culturing bottle etc. have fixed action magnetic separator frame device, be technical problem to be solved in the utility model.
Summary of the invention
For addressing the above problem, the invention provides a kind of magnetic resolution instrument, adopt following technical scheme:
A kind of magnetic resolution instrument, is characterized in that comprising base and main frame body, in described base, permanent magnet is set; Described main frame body is connected with base by four pillars; On the crossbeam of described main frame body along the horizontal and vertical strip elastic mechanism that evenly arranges respectively.
Further, four of described main frame body pillars are detachable connection with base.
Further, described strip elastic mechanism is connected with being connected to of crossbeam is detachable.
Further, the crossbeam of described main frame body is square.
Further, the crossbeam of described main frame body is that the length of side is the square of 90 ± 3mm.
Further, the distance between described adjacent two strip elastic mechanisms that are parallel to each other is 30.00 ± 3mm; Described strip elastic mechanism be adjacent and parallel crossbeam between distance be 30.00 ± 3mm.
Further, described strip elastic mechanism is bar-spring.
The beneficial effects of the utility model are as follows:
In the utility model on the crossbeam of main frame body along the horizontal and vertical strip elastic mechanism that evenly arranges respectively, when centrifuge tube or culturing bottle are placed on the base of magnetic resolution instrument, by the strip elastic mechanism of even setting, can the middle and upper part of centrifuge tube or culturing bottle be divided fixing; Preferably, described elastic mechanism is bar-spring, facilitates the plug of centrifuge tube, and reduces the wearing and tearing to magnetic resolution instrument.
2. four of the main frame body in the utility model pillars are detachable connection with base, and by main frame body, from being provided with the base separation of permanent magnet, main frame body can be used as test-tube stand separately; Simultaneously, when the sample separating until magnetic is contained in bottom compared with large and in the reagent bottles such as Erlenmeyer flask that middle and upper part is less time, reagent bottle can be placed on the base of magnetic resolution instrument of the main frame body of dismantling, and then main frame body is installed, more convenient like this operation, and avoid spilling of sample in reagent bottle.
3. the strip elastic mechanism in the utility model is connected with being connected to of crossbeam is detachable, after elastic mechanism is aging, can change easily; Can to strip elastic mechanism, dismantle as required, to meet the centrifuge tube of different sizes or the fixing needs of reagent bottle.
4. in the utility model, the crossbeam of main frame body is that the length of side is the square of 90 ± 3mm, the distance of stating between adjacent two strip elastic mechanisms that are parallel to each other is 30.00 ± 3mm, strip elastic mechanism be adjacent and parallel crossbeam between distance be 30.00 ± 3mm; The centrifuge tube of 50mL is convenient in such setting and the Tissue Culture Flask of 50mL carries out the operation of a large amount of magnetic resolution.
