Products Introduction：
SG-5404 series constant temperature 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
SG-5404A Type: speed stability, low noise, can work, continuously variable, durable。
SG-5404B Type: two-way mixing，can definite time。Drive power, suitable for mixing high viscosity liquid, with strong mixing capacity. Speed stability, low noise, can work, continuously variable, durable。
SG-5404C type: temperature, speed, dual display，can definite time,Drive power, suitable for mixing high viscosity liquid, with strong mixing capacity. Speed stability, low noise, can work, continuously variable, durable。

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.  High precision temperature control，The accurate control of experimental conditions
6.  Used for heating or heating and agitating at the same time
7. Suitable for different viscosity of liquid or solid-liquid mixture
8、Solution can be heated and the temperature setting and precise control
9、Stirring speed stepless adjustment, widely used in the mixing of different viscosity solvents
10、Load can be more than 10,000 hours continuous operation, long life, to adapt to continuous。
11、Heating plate both good thermal conductivity effect, and also has strong anti-cold properties
12、Heating plate at the bottom use double insulated equipmentm. fully improve efficiency and to avoid heat conduction to the chassis.
