Product introduction
SG-5401 series two-way heating Magnetic stirrer is the company to meet the needs of various types of laboratory, carefully designed and refined processing of production. Compared with similar products have significant advantages.small noise, Steady speed, full enclosed heated plate. by the PTFE and high-quality crafted magnetic sub-mixer. high temperature, abrasion resistance, chemical corrosion, magnetic properties, and can be carried out in closed mixing vessel work. very good and easy to use. At the same time heating the solution, so that the solution at a higher temperature in the fully mixed and reaction. it is widely used in biological medicine chemical chemical industry.
Features:
1. Novel appearance, easy operation
2. Stable performance, small size
3. Electronic control speed, motor torque larger, wide range of applications.
4. Used for heating or heating and agitating at the same time
5. Suitable for different viscosity of liquid or solid-liquid mixture
6. Stirring speed stepless adjustment, widely used in the mixing of different viscosity solvents
7. Load can be more than 10,000 hours continuous operation, long life, to adapt to continuous。
8. Heating plate both good thermal conductivity effect, and also has strong anti-cold properties
9. Heating plate at the bottom use double insulated equipmentm. fully improve efficiency and to avoid heat conduction to the chassis.
