Shanghai Hongguan Instrument talks about the precautions for magnetic stirrers when using

Magnetic stirrer is no noise, no vibration, electronic constant temperature, stirrer, widely used in colleges and universities, environmental protection, scientific research, health and epidemic prevention station, petroleum, chemical, medical, etc.
, magnetic stirrer on the analysis, stirring liquid high temperature heating stirring, which has a fast heating speed, high temperature value, uniform heating and other characteristics, is the general conventional constant temperature magnetic stirrer far from the reach, but also the ideal instrument
for modern laboratory laboratory laboratory personnel.

Precautions for the use of magnetic stirrer: 1.
Select the appropriate magnetic stirrer according to the application; 2.
When using it for the first time, check whether the parts of the instrument are aligned with the instrument manual, such as stirrers, power cords, etc.
; 3.
When using, it should be able to make the instrument ground well; 4.
When the solution is placed in the container, do not be too full, and leave enough space to avoid the solution spilling out during the stirring process and corroding the disk body; 5.
When regulating the speed, it should be gradually adjusted from low speed to high speed, do not start directly from the high speed gear, so as not to cause the stirrer to be out of sync and cause beating; 6.
Medium speed operation can extend the service life of the agitator; 7.
If the stirrer beats or does not stir when stirring, please check whether the beaker is stable, whether the position is flat, and whether the speed is appropriate; 8.
When turning the timer switch, it should not be too fast and too violent, so as to avoid damage (only for models with timing function); 9.
The height of the temperature measurement probe into the solution should be appropriate, and the stirrer cannot be made to collide with the probe to prevent damage to the probe (corresponding to the water bath collector magnetic stirrer, because its temperature measurement probe is integrated inside the water bath pot, there is no such limitation); 10.
Ordinary heating type magnetic stirrer, can not be heated when not stirred, continuous heating above 70 °C shall not exceed 2 hours (water bath collector magnetic stirrer without this restriction); 11.
The instrument should be kept clean and dry, especially do not let the solution into the machine, after use, the temperature measurement probe, stirrer, etc.
should be cleaned, and the surface of the disk should be wiped clean with a clean cloth
