JB-12Magnetic heating stirrer

12The joint magnetic heating stirrer is an improved version of the magnetic heating stirrer developed and produced by our company. It has single point and multi-point simultaneous stirring and heating functions, is easy to operate, runs smoothly, and has stepless speed regulation. It can accurately and stably stir liquid solutions within a wide speed range, especially suitable for small volume samples. It is a tool for petroleum, chemical, pharmaceutical and health, environmental protection, biochemical laboratories, analysis laboratories, education and scientific research.

1. Introduction
This instrument is widely used in various universities, environmental protection, scientific research, health, epidemic prevention, petroleum, metallurgy, chemical, medical and other units. According to the requirements of the majority of users, it is designed with multi connected heating, stirring and constant temperature control such as two connected, four connected, and six connected. Enable users to obtain corresponding effects and data for multiple samples simultaneously. This instrument has good performance, low noise, and stirring, making it an ideal tool for laboratory technicians.

3Hot wire power consumption:12X150W
4Motor speed:zhigh2000turn/divide

3、 Usage method
When using this instrument, first check if all the accessories accompanying the machine are complete. Then, install the fixtures in order and place the beaker that needs to be stirred in the center of the plating plate. Add the solution and place the stirrer in the beaker solution. Then, plug in the power plug of the instrument, turn on the power speed switch, and the indicator light will light up. When heating is needed, start working,Turn on the heating power switch,The speed regulation is gradually adjusted from low speed to high speed, and it is not allowed to start the high speed gear directly to avoid the agitator not being synchronized and causing jumping. When not working, the power should be cut off. To ensure safety, please connect the ground wire when using. The instrument should be kept clean and dry, and it is strictly prohibited for solution to enter the machine to avoid damaging the parts and prevent severe vibration.

5、 Precautions
1When the stirrer jumps or does not stir during mixing, please cut off the power and check if the bottom of the beaker is flat and the position is correct. Please also measure if the current voltage is220Vpositive and negative10VOtherwise, the above situation will occur.
2The heating time should generally not be too long, and intermittent use can prolong the service life.
3Continuous operation at medium speed8Hours, high-speed operation can work continuously4Hour.
