SG-5405 series digital display  constant temperature multi-head  Magnetic stirrer is the company to meet the needs of various types of laboratory, carefully designed and refined processing of production.. SG-5405 series two together, four together, six joint heated magnetic stirrer，Multiple samples simultaneously mixing，Multiple samples can also be effective and relevant data。. The instrument performance is good, no noise, no vibration, good mixing effect, variable speed, beautiful shape. Speed steady, fully enclosed heating 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.
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. High precision temperature control，The accurate control of experimental conditions
6. Suitable for different viscosity of liquid or solid-liquid mixture
7. Used for heating or heating and agitating at the same time
8. Stirring speed stepless adjustment, widely used in the mixing of different viscosity solvents
9. Load can be more than 10,000 hours continuous operation, long life, to adapt to continuous。
10. Heating plate both good thermal conductivity effect, and also has strong anti-cold properties
11. Heating plate at the bottom use double insulated equipmentm. fully improve efficiency and to avoid heat conduction to the chassis.
12. According to the arrangement of mixing head, there are several forms: single row 2, single row four, two-column 4, a separate six, two-column six. user preferences based on their use and flexible options.
