Instructions

1. Place the stirrer stably, and place the beaker containing the liquid medicine in the middle of the workbench (that is, the electric furnace). And put in an appropriate stirring bar, adjust the two adjustment knobs counterclockwise to the minimum, plug in the power supply, turn the timing switch to "ON" (open), or the scale that needs timing, the power indicator light is on;

2. Slowly rotate the speed control knob clockwise to make the stirring bar in the beaker rotate from slow to fast to stir the liquid medicine until the required stirring speed;

3. When the liquid medicine needs to be heated, turn the button switch on the back of the machine down, the temperature rise indicator light is on, the electric furnace is energized to generate heat, the heating power of the electric furnace is adjusted by the temperature adjustment knob, and the voltmeter displays the heating Voltage;

4. If automatic temperature control is required, the two lead wires of the electric contact mercury thermometer (prepared by the user) can be connected to the two terminals on the back of the machine. When the temperature reaches the preset temperature, it will automatically stop heating, and when the temperature is lower than the preset temperature, it will automatically resume heating, so as to achieve automatic temperature control; Note: the electric furnace has a certain thermal inertia, that is, when it is heated to the preset temperature, the electric furnace has been cut off The light is off), but the remaining heat will still heat the liquid to make it warm up, which will affect the temperature control accuracy. At this time, the heating power can be appropriately lowered.

5. The maximum temperature on the surface of the H97 constant temperature magnetic stirrer electric furnace exceeds 300 ℃. When heating the liquid medicine, the temperature that the liquid medicine can reach is inversely proportional to its amount;

6. After use, unplug the power supply, clean the appearance after cooling down, and store it.

Precautions

1. The power socket should have good grounding;

2. The machine should be avoided to be used in a humid environment;

3. When the H97 constant temperature magnetic stirrer is in use, the beaker should not be too full to prevent overflow during stirring;

4. This machine cannot be used alone as an electric furnace.
