Background technique

It is well known that being extracted using magnetic material in the research fields such as biology and medicine detection and separating various biologies Macromolecular (such as bioactive molecules such as cell, DNA, RNA, protein and viruses) is gradually received by different field, and gradually Substitute that original time-consuming, laborious, extraction efficiency is low or virose conventional method (organic solvent extracting and column mention), magnetism point The advantage that can not be substituted another from technology be can extensive Multi-example operation repetitive, be suitable for full-automatic operation platform, the whole world Have a research and development that more trans-corporations set foot in magnetic material and corresponding equipment, magnetic separation technique be will combine it is to be separated The magnetic material of sample is added to containing sample to be separated and is suitable in the solution that magnetic material is combined with sample to be tested, equimagnetic Property material sufficiently combined with sample to be separated after, by magnetic separator to magnetic material mixed solution apply external magnetic field, outside Under the action of magnetic field, the magnetic material for being combined with sample to be separated is separated from solution, to realize biology to be separated The enrichment of sample, however, different magnetic material is different to the magnetic responsiveness in magnetic field, if different magnetic materials all use it is identical Magnetic field carry out Magneto separate, then magnetic responsiveness it is weak magnetic material needs could be separated under magnetic field environment for a long time, consuming Time on the contrary, short between the strong magnetic material magnetic timesharing of magnetic responsiveness, but is easy precipitating of reuniting in high-intensity magnetic field again, influences point From purification effect.

Utility model content

In order to solve the above technical problems, to provide a kind of magnetic field adjustable to adapt to the controllable of different magnetic materials for the utility model Magnetic separator.

A kind of controllable magnetic separator of the utility model, including main body support and electromagnet, main body support include two groups Centrifuge tube shelf, two pack supports and two groups of pedestals, two pack support tops are connect with two groups of centrifuge tube shelfs respectively, two pack support bottom ends point It not being connect with two groups of pedestals, centrifugation pore group is provided on two groups of centrifuge tube shelfs, electromagnet includes iron core and coil group, and two groups Bracket is connected by iron core, and the equal vertical wrap of coil group further includes conducting wire group, electric wire and power regulator, electricity on the outside of iron core It is provided with voltage knob, current knob and socket on the adjuster of source, is connected between coil group by conducting wire group, coil group passes through electricity Line is electrically connected with power regulator.

Compared with prior art the utility model has the following beneficial effects: centrifugation pore group can accommodate 1.5mL or 2mL centrifugation Pipe, for power-supply timer by socket external power supply, voltage knob and current knob can distinguish voltage and electricity in control coil group Stream replaces permanent magnet to isolate and purify magnetic material by electromagnet, when being intended to purifying biological molecule, equipped with biology point The centrifuge tube of son and magnetic material is placed on centrifuge tube shelf, is powered on by socket, is rung for the magnetic of different magnetic materials Ying Xing, by the size of current or voltage in power regulator regulating magnet, when thering is electric current to pass through in magnet spool, There is magnetic field generation in the two sides of coil, the iron core among coil can reinforce this induced magnetic field, and this induced magnetic field is in coil The position of two side stands is most strong, therefore the magnetic material in centrifuge tube can be separated by the magnetic field of this induction, is gathered in branch The centrifugation inside pipe wall of frame side, remove liquid in centrifuge tube can purified magnetic material, different magnetic material magnetic responsivenesses Difference only needs the size of current or voltage in regulating magnet coil, and then controls the power of induced magnetic field, to adapt to based on not Biomolecule with magnetic material isolates and purifies, and keeps magnetic field adjustable to adapt to different magnetic materials.
