Product introduction ：
SG-5407-type magnetic stirrer-type collector is the company to meet the needs of various laboratories, carefully designed and sophisticated manufacturing technology. In the domestic with leading level。SG-5407-type collector-type magnetic stirrer reasonable structure, good material, through the continuous improvement of technical staff，A fundamental solution to the reaction on the spherical vacuum flask，Pressor response to the long mixing, heating temperature of the problem, water, oil,dry multi-purpose。The machine uses a solar collector heating method，The solution is heated compley uniform strong thermal radiation, the heating speed, saving energy。Configuring high-quality magnet and PTFE stir rotor，more durable，Well received by users。

use method：

1．Open the lid of  stainless steel container，poured the oil Medium  into the stainless steel container，Heat pipe solution had to be full。
2．Put mixing rotor Into the solution。Turn on the power，Indicator light starts，Open magnetic stirring switch，Clockwise rotation speed control button，Stirring speed from slow to fast， speed can be increased to the required。
3．When you are heating，First with temperature sensor probe clip at the scaffold， frame so that the temperature sensor probe into the solution of not less than 5cm，But can not affect the mixing。
4．Set temperature：Slowly adjust the temperature control knob to the temperature you need, the red light indicate that the heating（Temperature can be directly read out from the header, more intuitive），Green light is that the constant temperature。
5．If the rotor Jumping，Please turn off magnetic stirring switch and restart   ，Speed can be adjusted from slow to fast return to normal work。

Attention
1、 To ensure your personal safety，Please use the three-phase safety sockets，contact with ground when you use。
2、Instruments used should be kept clean and tidy，if you not use Long-term please cut off power supply，Off switch to avoid accidents。
3、Stainless steel containers do not join the oil medium And the temperature sensor is not connected, please do not open the temperature control switch, so as not to damage the heating pipes and temperature table。
4、Before using this equipment, please read the instruction to avoid unnecessary trouble。
5、Our products are three packs a year, life-long maintenance。（Improper use or man-made damage to charging a handling fee）Please be assured that the use。
