Product introduction：
SG-5409 series of pulse timing  constant temperature magnetic stirrer is the company to meet the needs of various types of laboratory，based on  After years of production the magnetic stirrer，Introduction of foreign advanced technology and production processes，R & D for domestic users a series of high-grade magnetic stirrer products。With noise, smooth speed control, temperature control and high precision, long life, mixing the advantages of large。with a timer function，mixing can be preset limit。By the PTFE and high-quality crafted stir rotor，high temperature, abrasion resistance, chemical corrosion, magnetic properties, and can be carried out in closed mixing vessel work。

Technical parameters：
1、Heating plate made of aluminum alloy and external coating Teflon，To both good thermal conductivity effect, and also has good resistance to hot and cold, corrosion resistance。
2、Heating plate at the bottom use double insulated equipmentm. fully improve efficiency and to avoid heat conduction to the chassis
3、This product's chassis and the upper convex design can prevent accidental overflow in the mixing process of the solution into the blender internal damage to electronic devices
4、Load can be more than 10,000 hours continuous operation, long life, to adapt to continuous。
