1, the use of magnetic stirrer?
Turn on the power, the indicator light is on, then adjust the speed knob clockwise, the speed from slow to fast, adjusted to the desired speed, the stirrer rotates to drive the solution for stirring operation. When constant temperature heating is required, insert the temperature measuring probe into the solution and insert the plug into the stirrer seat (corresponding to the water bath collector-type magnetic stirrer, because its temperature measuring probe is integrated inside the water bath without this step), adjust the temperature knob to the desired temperature.
2, Note
Choose the appropriate magnetic stirrer according to the application, the first time you use, check the instrument against the instrument manual to see if the instrument is complete, such as stirrer, power cord and so on. When using the instrument, it is best to make the instrument well grounded. When you put the solution into the container, please do not overfill it, and leave enough space, so as not to spill out the solution and corrode the disks during the stirring process.
Working Principle of Magnetic Stirrer
Using the characteristic of repulsion of magnetic material, the magnetic stirrer is driven to rotate by changing the polarity of the two ends of the base, and the sample is rotated by the rotation of the magnetic stirrer, so as to make the sample evenly mixed; the sample is heated by the temperature control board at the bottom, and the sample is heated evenly by the rotating magnetic stirrer, so as to reach the specified temperature. The sample is heated by the bottom temperature control plate, and the rotation of the magnetic stirrer makes the sample evenly heated to reach the specified temperature; the heating power can be adjusted to make the heating speed controllable, so as to apply to a wider range of sample treatment processes.
