1.1 Introduction
BG-stirrer series ultra-thin magnetic stirrer adopts professional electromagnetic principle, which abandons the heavy shape of the traditional stirrer and makes it lighter; it is durable, Huidian Yuehua control, stepless speed regulation, stirring Automatic centering, automatic low-speed start and automatic gradual increase and decrease of speed effectively prevent the external environment of liquid. The stainless steel ultra-thin shape and fully enclosed moisture-proof structure maximize the use of space. It can be widely used for cultivating knots and freezing Special environment with narrow space and low temperature and humidity,
BG-stirrer is specially designed for laboratories, it is widely used in laboratories of chemical industry, schools and research institutes, BG- stirrer 1D can stir one container, BG-stirrer4D1 is suitable for stirring up to 4 containers, each container Consistent stirring speed, BG-stirrer4D4 can simultaneously stir up to 4 containers at different speeds.
