1brief introduction

CJ-H20typeMagnetic stirrers are widely used in various universities, environmental protection, scientific research, health, epidemic prevention, petroleum, metallurgy, chemical, medical and other units. This instrument has good performance, no noise, no vibration, and is suitable for stirring. The workbench is made of stainless steel and corrosion-resistant, making it an ideal tool for laboratory technicians.

2、 Performance

1Electricity Source: Single phase50HZ 220V±10V

2Electric power:8W

3Infinite speed regulation:0-2500change/divide

4Large mixing capacity:2000ML

5Work disk size:160*160mm

3、 Usage method

When using this instrument, first check if the accessories accompanying the machine are complete, and then place the beaker that needs to be stirred in the center of the workbench. 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 control switch, and the indicator light will turn on to start working. The speed control is gradually adjusted from low speed to high speed. It is not allowed to start the stirrer directly from high speed to avoid asynchronous operation and 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.

4、 Precautions

1When the stirring element jumps or does not stir during stirring, please cut off the power and check whether the bottom of the beaker is flat and the position is correct. At the same time, please measure whether the current voltage is220VBetween ± 10V, otherwise the above situation will occur.

2Medium speed operation can work continuously for 8 hours, while high-speed operation can work continuously for 4 hours.
