Magnetic conversion separation device

Abstract

The invention discloses a magnetic conversion and separation device, which is mainly composed of at least a test tube holder and a magnetic piece; the test tube holder is used to arrange at least a test tube; the magnetic piece can produce magnetic suction; the magnetic piece is mutually pivoted with the test tube holder; therefore, the test tube holder and the magnetic piece can be rotated by taking the pivot end as the center, so that the test tube arranged in the test tube holder can be relatively separated from the magnetic piece or can get relatively near the magnetic piece to adjust the magnetic intensity generated by the magnetic piece onto the mixture in the test tube.

Description

technical field [0001] The present invention relates to a magnetic conversion separation device, especially a device that changes the relative position between the magnet and the test tube through the rotation of the mechanism, through which the trace target substance can be separated from the complex mixture contained in the test tube to obtain a high-purity substance for the benefit of Magnetic particle separation device for post-purification treatment. Background technique [0002] The magnetic separator is applied to the separation and purification of magnetic particles, which can efficiently separate trace target substances from complex mixtures and obtain high-purity substances. However, in the general magnetic separation procedure, when the magnetic particles are separated and the remaining unnecessary solution is removed, the steps of washing and eluting must be repeated, and this repeated step often requires the test tube to be taken out of the separator.

[0006] Another example is the European published invention patent EP1621890 "Device and method for separating, mixing and concentrating magnetic particles with fluid and use thereof in purification methods", which discloses a multi-layer test tube with different cross-sectional areas. The test tubes are arranged in a linear array, and then Cooperate with the magnet assembly in the staggered geometric array, through the staggered action of moving the magnet and adjusting the upper and lower positions of the test tube, the trace target substance can be separated from the mixture in the test tube in layers; however, the position coordination of the magnet and the test tube is complicated and difficult to operate , and there needs to be enough space to make the test tube completely detached from the magnet assembly
