Magnetic separators. A variety of magnetic separators are available on the market, ranging from very simple concentrators for one tube to complicated fully automated devices. The isolation of nucleic acids is mostly performed in the batch mode using commercially available lab-scale magnetic separators (particle concentrators).
The third category of magnetic separators is based on superconducting magnets which generate the highest intensity magnetic field [64], [65]. Superconducting magnets are capable of generating magnetic field from 2 to 10 T. More references on this magnet have been discussed in the direct purification method described below.

The heavy-media separation process, or HMS, employing ferrous media, usually ferrosilicon and/or magnetite, is the most generally used process for sink-float separations. A stable medium over the range of specific gravities from 1.25 to 3.40 can be maintained within close limits and is cleaned and recovered by magnetic means.

In plants of all enrichment levels, magnetic ...
Magnetite-based magnetic separators have proven to be effective in specific laboratory experiments, indicating a potential feasibility for scale-up operations. Column media-filter type filtration effects indicate a magnetite-based column would not be suitable for treatment of a waste stream with a high diamagnetic solids content or high volume ...
To facilitate manual retrieval of conventional tracers from drain-and-rinse screens, it is common to use large density tracers: 32 mm for DMCs with feed topsize up to 80 mm (see Figure 1), and 32 mm or 64 mm in dense medium baths and vessels. Fine-density tracers are used for spirals and for elutriation-based separators.
