Product introduction：
SG-5411 series timing two-way thermostatic magnetic stirrer is the company to meet the needs of various laboratories, carefully designed and refined processing of production.Using strong magnetic magnets, high power motor, high-capacity face, the whole beautiful shape, easy to operate，With two-way, regular mixing function, digital control temperature.Widely used among major colleges, environmental protection, scientific research, health, disease prevention, petroleum, metallurgy, chemical, medical and other units, The instrument performance is good, variable speed, beautiful shape. Speed steady, fully enclosed heating plate.Achieved by controlling the component unit time-cycle of positive and negative direction to enhance the mixing effect of stirring，At the same time the solution is heated and the temperature setting and precise control，So that the solution to determine the temperature conditions in the fully mixed reaction，It is widely used in biological / Medicine /Chemical / chemical fields.

Features:
1. Novel appearance, easy operation
2. Stable performance, small size
3. Electronic control speed, motor torque larger, wide range of applications.
4. With timing function，mixing can be preset limit
5、No noise, no vibration
6、Positive and negative direction of time-loop, automatic commutation, mixing the best
7、By the PTFE and high-quality crafted magnetic sub-mixer, high temperature resistance, wear resistance, chemical corrosion, magnetic properties, and can be carried out in closed mixing vessel to work very well and easy to use.
8、Precise temperature control, high accuracy, precision control.
9、Load can be more than 10,000 hours continuous operation, long life, to adapt to continuous.
10、Used for heating or heating and agitating at the same time

11、Stirring speed stepless adjustment, widely used in the mixing of different viscosity solvents
12、Heating plate both good thermal conductivity effect, and also has strong anti-cold properties
13、Heating plate at the bottom use double insulated equipmentm. fully improve efficiency and to avoid heat conduction to the chassis.
