Magnetic particle separating device, and method of separating and purifying nucleic acid or protein using same

A magnet particle separating device comprising:

• a plurality of induction magnets with magnetic fields for attracting magnetic particles;
• an induction magnet fixing part having induction magnet fixing holes into which the induction magnets are inserted for fixing the induction magnets;
• and
• a body with which the induction magnet fixing part is combined, the body having entry holes, including first entry hole and a second entry hole adjacent to each other, each formed downward from a top surface of the body along a height direction which is a vertical direction for inserting a tube therein such that the entry holes correspond to array position of the induction magnets, and the body having a compartment wall comparting the first entry hole for receiving a first tube therein and the second entry hole for receiving a second tube therein,
• wherein plural induction magnets of the plurality of induction magnets are arranged in the vertical direction along each entry hole,
• wherein,
• the compartment wall comprises:
• an insertion hole formed on the compartment wall along a longitudinal direction of the compartment wall, which is orthogonal to the height direction;
• and a single tube-fixing member positioned in the insertion hole, exposed to the first entry hole and the second entry hole, and configured to compress an outer surface of the first tube being inserted along the height direction into the first entry hole and an outer surface of the second tube being inserted along the height direction into the second entry hole to fix the first tube and the second tube to the body, or
• the body comprises:
• a groove portion penetrating the compartment wall along a width direction of the compartment wall, which is orthogonal to the height direction and the longitudinal direction;
• and a single tube-fixing member positioned in the groove portion, arranged along the width direction, exposed to the first entry hole and the second entry hole, and configured to press an outer surface of the first tube being inserted along the height direction into the first entry hole and an outer surface of the second tube being inserted along the height direction into the second entry hole to fix the first tube and the second tube to the body.
