Embodiment Construction

[0024] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0025] Such as figure 1 , figure 2 As shown, the present invention includes a tray 1, on which a group of electromagnet arrays made up of a plurality of small electromagnets 2 is arranged, and each small electromagnet 2 includes a magnetic core 3 and a magnetic core 3 surrounded by a A coil 4 wound with multiple turns of wire, and the two ends of the coil 4 are connected to a power supply. A cover plate 5 is arranged above the electromagnet array, and holes are opened on the cover plate 5 to allow corresponding small magnetic cores 3 , and a pair of retaining springs 7 are arranged in two corresponding frames 6 of the tray 1 . A microporous plate 8 is arranged on the top of the cover plate 5 , and the two sides of the microporous plate 8 are clamped under the two retaining springs 7 .

[0026] In the above-mentioned embodiment, the quantity of sma...

Abstract

A millipore plate electromagnetic separator includes a salver; an electric magnet array consisting of a plurality of small electric magnets is arranged on the salver; each small electric magnet includes a magnetic core and a loop sheathed outside the magnetic core; the two ends of the loop are connected with powers; the upper surface of the electric magnet array is provided with a cover plate; a hole corresponding to the magnetic core is arranged on the cover plate; a pair of clamping springs are arranged in the two corresponding frames of the salver; a millipore plate is arranged at the top part of the cover plate and is clamped on the lower surface of the two clamping springs; the centers of 4 to 6 neighboring millipores on the millipore plate are corresponding to one small electric magnet. The millipore plate electromagnetic separator has the advantages of simple structure, low cost, fast separating speed and high efficiency; can realize single or uniformed control on each small electric magnet, is flexibly operated, is conveniently combined with an automatic plate washing device to realize the automatization of separation and can play the important roles on the aspects like clinical laboratory, environment detection, bioanalysis, drug screening, etc.

Description

technical field [0001] The invention relates to a magnetic separator, in particular to a microporous plate type electromagnetic separator which uses magnetic particles as a separation reagent for immune analysis. Background technique [0002] Since immunoassay was proposed in the 1950s, great progress has been made in half a century, and now it has been widely used in environmental, clinical, food and industrial analysis. Along with the development of immunoassays, the separation methods of immunoassays are constantly being updated. Immunoassays can be divided into homogeneous immunoassays and heterogeneous immunoassays. Homogeneous separation methods include immunoprecipitation assays (including precipitation and aggregation) and liposome dissolution assays. The homogeneous separation method does not need to be separated from excess reagents during the analysis process, but in practical applications, due to many insurmountable problems, its application proportion is very s...
