Magnetic stirrer used in quality control and research & development departments of manufacturing industries. This device rotates a magnetic stir bar to uniformly mix liquid samples, used for solution preparation and reaction acceleration in chemical analysis, material testing, and quality inspection. Various specifications are available including hot stirrers with heating function, digital speed control, and timer-equipped models. Unlike centrifuges or shakers, it features non-contact stirring using magnetic force, minimizing contamination risks. Essential basic laboratory equipment for solvent mixing, pH adjustment, titration analysis, and quality control testing in laboratories.
