Description
Technical field
The utility model relates to a kind of magnetic frame, particularly a kind of combined magnetic force frame.
Background technology
Utilize super paramagnetic beads microparticle to obtain extensive use in the technology of liquid phase separation large biological molecule on biomedical boundary, as isolated protein, antibody, with nucleic acid etc.After the liquid containing magnetic bead microparticle puts into micro-test tube, when not having magnetic force, magnetic bead microparticle can distribute in the liquid phase after agitation; But when this micro-test tube is placed in a magnetic field, super paramagnetic beads microparticle is magnetized and attracted to the strongest position, magnetic field and be gathered into closely one on micro-test tube wall simultaneously.
Though existing magnetic frame product can partly meet user's requirement, there are many deficiencies.Comprise:
1) most of magnet and micro-rack for test tube are designed to integrated inseparable opening structure, and user needs repeatedly to repeat the one by one transfer of micro-test tube between magnetic frame and common micro-rack for test tube.
2) hole of putting micro-test tube is designed to regular circle, and simultaneously for adapting to the diameter difference of micro-test tube of numerous producer, the diameter in hole is forced to the maximum of the diameter being greater than micro-test tube that market finds, make most of micro-test tube reliably not be fixed in hole, the process of overturning mixing cannot be completed.
3) after hole put into by micro-test tube, the flange of its mouth of pipe and the upper plane of shelf fit tightly, and make to take off micro-test tube difficulty.
4) shape of magnet and position are not optimized, and make that the magnetic bead aggregation of formation is loose, at the bottom of pipe, (as used vavuum pump extracted liquid) magnetic bead loses simultaneously in washing process.
5) the micro-test tube at the bottom of multiple pipe can not be adapted to.
