Abstract

A magnetic substance separation device is configured for attracting magnetic substances in a sample within a sample container. The magnetic substance separation device includes a casing and at least one magnetic component assembly. The casing has at least one accommodation compartment. The at least one magnetic component assembly is disposed in the at least one accommodation compartment, and the at least one magnetic component assembly includes at least four cubic magnetic components. In addition, the at least four cubic magnetic components are linearly arranged with different magnetization directions, allowing magnetic field lines of the at least one magnetic component assembly to concentrate on one side, such that the at least one magnetic component assembly forms at least one strong magnetic surface on the casing. The at least one strong magnetic surface is configured to attract the magnetic substances in the sample within the sample container.

Claims (13)

1 . A magnetic substance separation device, configured for attracting magnetic substances in a sample within a sample container, and the magnetic substance separation device comprising:

a casing, comprising a main housing, a plurality of partitions and a base, the plurality of partitions are arranged in the main housing to form a plurality of parallel elongated grooves on the main housing, the base is secured to the main housing for forming a plurality of accommodation compartments together with the main housing and the plurality of partitions, and the base having a plurality of openings respectively connected to the plurality of accommodation compartments;

a holder, disposed on an upper end of the casing and including a through hole, wherein the holder is configured to secure the sample container onto the at least one strong magnetic surface of the casing, and the through hole is configured for a tube part of the sample container to be disposed through, allowing the tube part to correspond to the at least one strong magnetic surface, and a periphery of the through hole is configured to support an opening flange part of the sample container;

an inclined support pivotally coupled to an end of the casing, wherein the inclined support is configured to selectively raise a horizontal height of the end of the casing to be greater than or equal to a horizontal height of other parts of the casing; and

at least one magnetic component assembly, comprising at least four cubic magnetic components, the at least four cubic magnetic components are inserted into the accommodation compartments through the plurality of openings, wherein the at least four cubic magnetic components in one of the plurality of accommodation compartments are arranged in an offset configuration relative to the at least four cubic magnetic components in another of the plurality of accommodation compartments;

wherein the at least four cubic magnetic components are linearly arranged with different magnetization directions, allowing magnetic field lines of the at least one magnetic component assembly to concentrate on one side, such that the at least one magnetic component assembly forms at least one strong magnetic surface on the casing, and the at least one strong magnetic surface is configured to attract the magnetic substances in the sample within the sample container.

2 . The magnetic substance separation device according to claim 1 , wherein the at least four cubic magnetic components are arranged in Halbach array.

3 . The magnetic substance separation device according to claim 1 , wherein the at least one magnetic component assembly further forms a weak magnetic surface on the casing, and the weak magnetic surface and the at least one strong magnetic surface are located on opposite sides of the casing.

4 . The magnetic substance separation device according to claim 1 , wherein the at least one magnetic component assembly comprises a plurality of magnetic component assemblies, and the plurality of magnetic component assemblies are respectively disposed in the plurality of accommodation compartments.

5 . The magnetic substance separation device according to claim 4 , wherein each two adjacent cubic magnetic components within the same accommodation compartment are in physical contact with each other.

6 . The magnetic substance separation device according to claim 4 , wherein the casing has a plurality of partitions, the plurality of partitions are respectively disposed between two adjacent accommodation compartments, a thickness of each of the plurality of partitions ranges from 1.0 mm to 10.0 mm, and a thickness of the casing at the at least one strong magnetic surface ranges from 1.0 mm to 10.0 mm.

7 . The magnetic substance separation device according to claim 1 , wherein the at least one magnetic component assembly is in physical contact with an inner peripheral surface of at least one accommodation compartment.

8 . The magnetic substance separation device according to claim 1 , wherein a side length of each cubic magnetic component ranges from 1 mm to 15 mm.
