Magnetic stirrer is a basic experimental instrument that everyone is familiar with, and it is now widely used in many fields, bringing a lot of convenience to our experimenters. However, when operating and using magnetic stirrer, there are some simple maintenance and upkeep that we still need to understand. Below, we will introduce them to you.
1. Do not let the instrument work without heating the liquid.
2. Before operating the machine, it should be checked whether it is grounded to ensure completion before starting work.
3. In order to ensure that the instrument is not damaged, insulation materials are usually placed inside the instrument. Therefore, when we use the magnetic stirrer for the first time, we may notice a small amount of white smoke or a pungent smell. These are normal phenomena and not product quality issues. Keeping it ventilated is sufficient.
4. The internal components of the magnetic stirrer have an upper limit on heating, so it is important to consider this when heating. The solution is to ensure that the machine does not only heat up, and remember to change the motor state to rotating, which can maximize the protection of the magnetic stirrer.
5. After the heating work is completed, be sure to turn off the heating first, and wait for a few minutes until the temperature has dissipated before turning off the stirring.
6. It is necessary to ensure a dry operating environment, as the instrument is prone to leakage and other phenomena in a humid environment. This is also why it is necessary to ensure that the instrument is grounded. If the instrument is very humid, it must be dried with hot air.
7. Be careful during the operation to avoid burns, as the temperature is usually relatively high.
8. For safety reasons, there is a fuse on the back of the instrument that can be checked for replacement if the device still does not work after being powered on.
If you are using a magnetic stirrer, as long as you pay attention to its use and maintenance, you can definitely extend the service life of the equipment and make it work better for us.
