Device for separation of magnetic particles from dispersion at boundary surface, has permanent magnet present below non-magnetic funnel to absorb dispersions, and boundary surface arranged between lower outlet opening of funnel and magnet

摘要

The device has a permanent magnet present below a non-magnetic funnel for absorbing dispersions. A boundary surface is arranged between a lower outlet opening of the funnel and the permanent magnet. The magnet is made of neodymium iron boron, samarium cobalt or aluminum nickel cobalt. The funnel is made of Teflon(RTM: PTFE). The outlet opening of the funnel exhibits diameter of about 100 micro meters. Dimensions of the magnet of about 9mm x 18mm x 18mm are formed in accordance with dimensions of the funnel. An independent claim is also included for a method for separation of magnetic particles from dispersion at a boundary surface.
