[0036] Example 2

[0037] Preferably, a magnetic absorption visual window 6 is embedded and connected to the front middle part of the magnetic frame body 1. When performing the magnetic absorption operation, in order to ensure the magnetic absorption effect, the magnetic frames mostly adopt a closed structure. The existing magnetic frames cannot observe the internal magnetic absorption conditions in real time under the closed structure, and the real-time performance is insufficient. By setting the magnetic absorption visual window 6, the magnetic absorption visual window 6 is a transparent and visible hard glass material, and the staff can view the internal magnetic absorption conditions in real time through the magnetic absorption visual window 6, thereby well reflecting the real-time performance of the magnetic frame.

[0038] Example 3

[0039] Preferably, a magnetic storage slot 7 is fixedly connected to the front bottom of the magnetic frame body 1. When the staff conducts real-time monitoring, they need to carry some tool parts, which increases the trouble of the staff.

[0044] Example 6

[0045] Preferably, a buffer spring bottom plate 502 is movably connected to the inner middle part of the magnetic frame base 5. When the magnetic frame is operated, manual pressing and other operations will produce a certain impact on the device body, causing certain damage to the device body. By setting the buffer spring bottom plate 502, the buffer spring bottom plate 502 has a shock-absorbing spring seat with multiple springs, which can generate a good buffering force when the staff touches it, thereby greatly improving the buffering property of the magnetic frame.

The sizes and shapes of the centrifuge tubes are different. The existing device cannot use the same magnetic frame to make centrifuge tubes of multiple specifications for extraction and use, and the applicability is insufficient. By setting a centrifuge tube slot 2 applicable to multiple calibers, the centrifuge tube adjustable slot 201 is set in the centrifuge tube slot 2 applicable to multiple calibers. The staff can drive the expansion and contraction movable rod 203 to expand or shrink by adjusting the roller shaft 202, thereby adjusting the caliber of the centrifuge tube. At the same time, a long tube embedding slot 204, a centrifuge tube batch embedding slot 205 and a rectangular tube embedding slot 206 are set, which can respectively adapt to different centrifuge tubes with longer lengths, larger quantities and rectangular shapes, thereby achieving the effect of flux operation and greatly improving the adaptability of the magnetic frame.

The magnetic strength of the existing magnetic frame is not enough. For smaller particle sizes, carboxyl magnetic beads, and polymers, The adsorption capacity of non-silicon hydroxyl magnetic beads such as styrene magnetic beads is weak, and more time is needed to wait for magnetic attraction. By setting up a high-flux magnetic device 3, a left adsorption magnetic column 302 and a right adsorption magnetic column 303 are arranged inside the high-flux magnetic device 3, which can strongly adsorb conventional magnetic beads. At the same time, an ultra-strong neodymium iron boron magnet 305 is arranged. The ultra-strong neodymium iron boron magnet 305 can effectively adsorb non-silicon hydroxyl magnetic beads such as smaller particle sizes, carboxyl magnetic beads, polystyrene magnetic beads, etc. At the same time, the staff can adjust the horizontal position and spacing of the magnets through the spacing adjustment wheel 304 and the lifting magnetic adjustment column 306 according to actual needs, thereby greatly improving the magnetic strength of the magnetic device.
