To provide a magnetic stand excellent in separability between magnetic beads and a liquid in magnetic separation, and to provide a magnetic separation method.SOLUTION: A magnetic stand includes: a base having an insertion hole into which a container is to be inserted, the insertion hole extending along a first axis; and a magnet provided on the base and having a magnetization that applies a magnetic field to the insertion hole. The magnet is disposed such that magnetic poles thereof face directions different from that of the container. When a plane including the first axis and determined such that a normal line of the plane is orthogonal to the first axis and passes through a center of the magnet is taken as a reference plane, and the magnetization is projected onto the reference plane, an angle formed by the first axis and the magnetization projected onto the reference plane is more than 0° and 90° or less.SELECTED DRAWING: Figure 12 【課題】磁気分離における磁性ビーズと液体との分離性に優れる磁気スタンドおよび磁気分離方法を提供すること。【解決手段】第１軸に沿って延在し、容器が挿入される挿入孔を有する基台と、前記基台に設けられ、前記挿入孔に磁場を印加する磁化を持つ磁石と、を備え、前記磁石は、磁極が前記容器とは異なる方向を向くように配置されており、前記第１軸を含む平面であって、法線が前記第１軸に直交するとともに前記磁石の中心を通過するように決定された平面を基準面とし、前記基準面に前記磁化を投影したとき、前記第１軸と、前記基準面に投影された前記磁化と、のなす角度は、０°超９０°以下であることを特徴とする磁気スタンド。【選択図】図１２
