METHOD FOR MANUFACTURING MAGNETIC BALL FOR BIOTECHNOLOGY, AND MAGNETIC BALL AND MAGNETIC PRODUCT

摘要

PROBLEM TO BE SOLVED: To provide a method for reducing and solving a limitation and a problem accompanied by "a fine particle" and "a micro-plate sample tube".;SOLUTION: The method for manufacturing a magnetic ball used in a biotechnology life science field includes the steps (i) mixing at least two magnetic particles and a resin raw material to prepare a particle dispersion resin raw material, (ii) providing the particle dispersion resin raw material to mold and obtaining a particle dispersion molded article, (iii) grinding and/or polishing the particle dispersion molded article to a spherical shape and forming a magnetic ball with a particle size 0.1 mm or more and 30 mm or less which has a saturation magnetization value of 2-200 A m²/kg and a residual magnetization value of 0-10 A m²/kg (however, saturation magnetization valueresidual magnetization value).;COPYRIGHT: (C)2011,JPO&INPIT
