Abstract:
    The present invention relates to a kind of magnetic separating column and its application in separating biological samples. The magnetic separating column has structure comprising a material holding section, a filler column, a discharge port and a pushing plug. The filler column is filled with small magnetic soft iron balls of sizes 0.01-0.1mm, 0.1-0.2mm and 0.2-1mm separately. During separation, the sample fed through the inlet in the upper end is made to flow through the filler column and the discharge port under the gravity action, and the pushing plug applies pressure to push out the blocked sample. Under the action of outer magnetic field, the magnetic separating column can generate high gradient magnetic field for effective fast separation of various kinds of cells, subcellular matters, bacteria, viruses, nucleic acids, proteins and other biological samples.
