This 90-1A single stirring magnetic stirrer is a large-capacity single stirring magnetic stirrer. It is driven by a brushless DC motor, with stable rotation speed, good speed regulation performance, large torque, and is not affected by the power frequency. The magnetic force is extremely strong and the structure It is sturdy and equipped with a high-power Voltage regulation output. An external heater and an electric contact mercury thermometer (prepared by the user) can automatically control the temperature. It is also equipped with an electric meter to display the rotation speed and output Voltage. It is suitable for large-capacity stirring.

1. Place the 90-1A single-stirring magnetic stirrer stably, place the container containing the liquid medicine in the center of the stirrer, put a stirrer in the container, adjust the knob counterclockwise to the minimum, plug in the power, and turn on the power. switch, the power indicator light is on.
2. Slowly rotate the speed control knob clockwise so that the stirrer in the container rotates from slow to fast to stir the liquid medicine to the required speed.
Note: The container needs to be made of non-ferromagnetic materials, and copper and aluminum containers should be avoided as much as possible. The bottom needs to be smooth and the thickness should not be greater than 10mm.
3. When the liquid medicine needs to be heated and stirred, connect the user-prepared heater to the three-pin plug, insert it into the socket at the back of the machine, put the heater into the container, be careful not to touch the stirrer, and turn the toggle switch on the back of the machine downward. , adjust the temperature adjustment knob, and the voltmeter indicates the heater Voltage;
4. If automatic temperature control is required, connect the two leads of the electrical contact mercury thermometer to the two terminals at the rear of the machine (the thermometer is inserted into the beaker of liquid medicine), and the temperature can be automatically controlled after setting the required temperature;
5. After use, unplug the power supply, clean the surface and store it away.
1. The power socket should be well grounded:
2. The liquid in the container cannot be overfilled to avoid overflowing during stirring;
3. It is forbidden to place the stirrer directly on the mixer for trial operation.
