Magnetic stirrer is an ideal analytical detector for liquid heating and stirring,special in thermostatic automatically regulating. With DC brushless motor, it possesses many advantages,such as lower noise,less mechanical breakdown and stable timing. The stirrer bar is made of telflon and high-quality alnico,so it is heat-resistant,abrasive resistant,anti-corrosive with high speed stirring. It is also efficient to mix and stir the liquid in the airtight vessel.
