Magnetic stirrer The magnetic stirrer is suitable for heating or heating and stirring at the same time. Suitable for liquids that are not very viscous, or solid-liquid mixtures. Using the principle of magnetic field and vortex, after putting the liquid into the container, the stirring piece is simultaneously put into the liquid. When the base generates a magnetic field, the stirring piece is driven to circulate in a circular motion, thereby achieving the purpose of stirring the liquid. working principle Using the characteristics of the same nature of the magnetic material, the magnetic stirring is rotated by constantly changing the polarity of both ends of the base. main effect The general magnetic stirrer has two functions of stirring and heating. Specifically: the first effect is to make the reactants mix evenly and make the temperature uniform. The second is to heat in a closed container, to prevent bumping, for example, in the distillation process, you can add zeolite , you can also use a magnetic stirrer, The third effect is to speed up the reaction, or the evaporation rate, and shorten the time. Instructions First check that the random accessories are complete, then install the fixture, place the beaker in the middle, and add the solution. Put in a stir bar. Follow the steps below; 1. Turn on the power; 2. Turn on the power switch; 3. Adjust the speed control knob to adjust the speed to the required speed from slow to fast, and do not allow the high speed gear to start, so as to avoid the jumper jumping due to non-synchronization; 4. When heating is required, turn on the heating switch to adjust the heating temperature; 5. When temperature control is required, insert the temperature sensor plug into the socket of the instrument back panel, insert the sensor probe into the test solution, and adjust the set temperature of the temperature controller to enter the temperature automatic control working state. Precautions during use 1. When stirring, when the stirrer is bouncing or not stirring, please turn off the power and check if the bottom of the beaker is flat and the position is positive. Please measure it at the same time. The current voltage is between 220V±10V, otherwise the above will occur. Happening. 2, the heating time is generally not too long, intermittent use to extend the life, not heating without stirring. 3. It can work continuously for 8 hours at medium speed, and can work continuously for 4 hours at high speed. It can prevent severe vibration during work. 4. Power consumption: The power socket should be a three-hole safety socket, which must be properly grounded. 5. The instrument should be kept clean and dry. It is forbidden to flow into the machine to avoid damage to the machine. When not working, the power should be cut off.
