3. The magnetic stirring electric heating jacket is reliable, easy to operate, and the structure of the whole machine is reasonable. The heating power is continuously adjustable, the heating power display is intuitive, it is convenient to observe and control the heating state, the stirring speed is continuously adjustable, it can meet different work needs, and it is easy to carry. It is an ideal equipment for the laboratory.

Main technical performance of magnetic stirring electric heating sleeve

1. Working voltage: 220V50Hz 2. Motor power: 20w60w80w100w3. Mixing speed: 2000 rpm, continuously adjustable 4. Heating power, 0-500w, pressure and temperature regulation, maximum temperature 400 degrees, accuracy plus or minus 1 degree 5. Working method: continuous working time greater than or equal to eight hours (mixing time) 6. Machine weight: 4kg 4. Operating method 1. Put the stirrer and the flask and beaker containing the solution on the heating jacket.

2. Turn on the heating control power supply, and the power indicator lights up. Turn the heating control knob right, and the heating control indicator lights up; The whole machine starts to work.

3. Turn on the mixing control power supply, the power indicator lights up, turn the right rotation speed control knob, and the mixer starts to rotate. Adjust the rotation speed only until the experiment needs it.

4. If the use of heating jacket adopts the constant temperature control of electric contact thermometer to achieve the purpose of intuitive temperature display, please connect one end of the equipped connecting wire to the electric contact thermometer and put it into the liquid to be measured; Connect the socket at the other end. (omit this item if there is no need for this function) then turn on the heating control switch, and the heating indicator light is on, indicating that the heating jacket is heating, and then gently rotate the heating control pressure regulating knob. The power of the heating jacket will produce different power with the change of the adjustment direction, and the working voltmeter will also display different voltage indexes. Clockwise adjustment will gradually increase the power and increase the service temperature, otherwise it will be the opposite.

Application method of magnetic stirring electric heating sleeve

1. Fix the upright rod in the screw hole above the back of the mixer, adjust the height of the cross clamp, fix the reaction bottle with a universal clamp, put in a suitable mixer, insert the power ~ 220 ∨, and turn on the switch.

2. Adjust the "mixing" knob clockwise to the appropriate position according to the speed display for mixing.

3. If the mixing capacity is large or viscous solution, the knob can be adjusted appropriately to increase the mixing force.

4. Adjust the temperature adjusting knob clockwise to a suitable position for heating and mixing as required.

5. If it is necessary to display the temperature, glass thermometer or digital thermometer can be used for auxiliary measurement.

Precautions for magnetic stirring electric heating sleeve

1. In order to ensure safe use, please be sure to use grounding wire.

2. In order to extend the use of the product, all the motors of the magnetic stirrer have the function of fan heat dissipation. Therefore, during the heating test, especially the high-temperature heating test, the instrument cannot be used for heating alone. Be sure to adjust the motor to the rotating or medium speed rotating state (or idling) to prevent the motor and electrical appliances from being damaged by high-temperature radiation. If the motor cannot start and rotate, it should be repaired by the dealer in time, otherwise it will not be responsible for damage or loss caused by not operating as required.

3. The temperature of the heating part is high, so be careful when working to avoid scalding.

4. At the end of high-temperature heating, please turn off the heating first, and then turn off the mixing after the residual temperature dissipates for a few minutes.

5. In case of wet hands, liquid spillage, or electric leakage under high humidity for a long time, it should be dried in time or dried naturally before reuse, so as to avoid danger.

6. When used for the first time, white smoke and peculiar smell emerge from the sleeve, and the color changes from white to brown and then to white. Because the glass fiber contains oil and other compounds in the production process, it should be placed in a ventilated place, and it can be used normally after disappearing in a few minutes.

7. The squeaking sound of the electric heating sleeve above 3000ml is due to the different structure of the furnace wire and is related to the SCR voltage regulating pulse signal, so it can be used safely.

8. When the liquid overflows into the sleeve, please turn off the power quickly, put the electric heating sleeve in a ventilated place, and use it after it is dry, so as to avoid the danger of electric leakage or electrical short circuit.

9. When not in use for a long time, please store the electric heating sleeve in a dry place without corrosive gas.

10. Please don't warm or dry.

11. When the ambient humidity is relatively high, induced electricity may be transmitted to the shell through the insulation layer. Please be sure to ground the wire to avoid leakage, and pay attention to ventilation.

12. Relative humidity: 35% - 85% (non condensing).
