Ⅰ.Introduction

HJ-4 magnetic stirrer is one of six-bar magnetic stirrers. It is an ideal analytical detector for liquid heating and stirring,special in thermostatic automatically regulating. With DC brushless motor, HJ-4 Magnetic Stirrer 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. HJ-4 Magnetic Stirrer is also efficient to mix and stir the liquid in the airtight vessel.
