When conducting experiments, such as constant temperature experiments or stirring experiments, we often think of two basic equipment commonly used in our laboratory: constant temperature water bath and magnetic stirrer. These two small devices are our powerful assistants during experiments. But if we need both stirring and constant temperature, some people may say that a constant temperature magnetic stirrer is sufficient. Indeed, this can meet the requirements, but those who frequently use it will find that this magnetic heating stirrer can only target one surface, often the bottom of the flask, and larger containers cannot achieve it. Some people say what to do, let me tell you below.
The combination of magnetic heating stirrer can effectively solve the above problems. Firstly, the good constant temperature performance of the constant temperature water bath can solve the limitations of the constant temperature magnetic stirrer's constant temperature ability, making the stirring experiment more efficient. In addition, the large space of the constant temperature water bath can also adapt to various flasks and even other containers. In addition, magnetic stirring has a very important characteristic in constant temperature water baths. As we all know, uneven water temperature may occur in larger water baths. If equipped with magnetic stirring, this problem can be well solved to make the water temperature more uniform.
The magnetic heating 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 the 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 magnetic stirrer 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 magnetic stirrer is not damaged, insulation materials are usually placed inside the magnetic stirrer. Therefore, when we use the magnetic stirrer for the first time, we may find that a small amount of white smoke or a pungent smell is emitted. 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. A good solution is to ensure that the machine does not only heat up, and remember to change the motor state to rotating, which can greatly protect 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. To ensure a dry operating environment, magnetic stirrers are prone to leakage and other phenomena in humid environments. 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 not to get burned during the operation of the magnetic heating mixer, 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.
