Using a magnetic stirrer is a common and essential procedure in many laboratory settings. Follow these steps to ensure safe and effective operation:
1. Before starting, make sure the power supply is properly connected and the speed control knob is turned to zero. This step is crucial for safety and prevents unexpected movement when you start the device.
2. Place the container with your solution on the designated area of the stirrer platform. Insert the magnetic stirring bar into the container, plug in the power cord, and turn on the power switch. The power indicator light should illuminate, confirming that the device is powered on.
3. Turn on the stirring function and the light if needed. Gradually increase the speed by turning the speed control knob clockwise, starting from low and moving to high as required. The magnetic bar will rotate the solution inside the container, ensuring even mixing.
4. If your model includes a heating function, connect the temperature sensor to the back of the device and adjust the temperature control knob to the desired setting. If no heating is needed, set the temperature knob to zero and unplug the sensor to avoid unnecessary energy consumption or potential damage.
5. If the temperature exceeds 70°C, limit continuous heating to no more than 2 hours to prevent overheating and possible damage to the equipment or sample.
6. When heating above 80°C, cover the container’s opening to reduce evaporation and maintain a stable temperature within the solution.
7. After completing the stirring process, gradually turn the speed control knob counterclockwise to return it to zero. If heating was used, also turn the temperature control knob to zero. Then, switch off the power and carefully remove the container from the stirrer.
8. Clean the stirrer and its surrounding area to maintain hygiene and extend the life of the equipment.
Important Notes for Safe Use:
1. Always set both the speed and temperature control knobs to zero before using the device.
2. Before operating, check that all accessories are secure and correctly installed. Place the solution in the center of the stainless steel plate, select the desired temperature, and start the stirring at a low speed. Gradually increase the speed as needed. Never heat without stirring, and always keep the device clean and dry. Avoid allowing any liquid to enter the internal components of the machine.
3. If the stirrer is not working properly or the bar isn’t rotating, check whether the beaker is placed flat and aligned correctly with the motor.
4. Operating at medium speed can help prolong the lifespan of the device.
5. Be cautious during heating to avoid burns or electrical hazards such as damaged cords.
6. For safety, always connect the grounding wire when using the stirrer.
7. After use, make sure both the speed and temperature controls are set to zero, and the power switch is turned off.
8. Limit stirring time to avoid overuse. Medium-speed operation can last up to 8 hours, while high-speed operation should not exceed 4 hours.
