Detailed description of heat collecting magnetic stirrer I. Function and use of heat collecting magnetic stirrer: I. The heat collecting magnetic stirrer has good performance, no noise, no vibration, and fast heating. It is an ideal tool for laboratory personnel in major universities, environmental protection, health, epidemic prevention, petroleum, chemical, medical and other units. 2、 Performance of heat collecting magnetic stirrer: 1. Power supply: 220V+10V 50HZ 2. Speed: 0-1250 rpm 3. Stirring power: 40W 4. Heating power: ≤ 800W 5. Temperature control range: RT-299 ℃ 6. Digital display temperature control 7. Can be used for water bath or oil bath 3. Usage of heat collecting magnetic stirrer: 1. Connect the power supply, prepare the cup, open the stainless steel container cover, place the cup in the middle of the stainless steel container, add thermal oil or silicone oil to the stainless steel container to the appropriate height, and place the stirrer into the cup solution. Turn on the power switch and the indicator light will turn on. Rotate the speed control potentiometer clockwise to increase the mixing speed from slow to fast. Adjust to the required speed. 2. When heating, connect the temperature sensor probe, clamp the probe on the bracket, move the bracket so that the temperature sensor probe is inserted into the solution for not less than 5 centimeters, but does not affect stirring. Turn on the temperature control switch, set the desired temperature, and press the+and - on the temperature controller to set the desired constant temperature. The numerical value displayed on the meter head is the actual temperature in the cup. The heating stops and automatically maintains a constant temperature. The collector type magnetic stirrer instrument can continuously heat and maintain a constant temperature for a long time. 3. If there is a jumping phenomenon in the mixer during work, please turn off the power and turn it back on. Adjust the speed from slow to fast to restore normal operation.. 4、 Precautions for heat collecting magnetic stirrer: 1. Please use a three-phase safety socket and ground it properly when using the heat collecting magnetic stirrer. 2. The instrument should be kept clean during use, and the power should be cut off if not in use for a long time. 3. Please do not turn on the temperature control switch when the stainless steel container is not filled with thermal oil and the temperature sensor is not connected, in order to avoid damage to the electric heating tube and thermostat.
