A magnetic stirrer is a device that is used in laboratories that helps to create a magnetic field that rotates. It consists of a stand, a small bar magnet and a rotating magnet.
The plate and bar magnet contains a rotating magnet and a coated plastic respectively. The rotating magnet can be charged especially as it is able to make a rotating magnetic field. Individuals who haven't been opportuned to make use of this instrument would find it difficult to commence or rather understand its use.
It would interest you to know that the stirrer is prominently used in both chemistry and biology labs. One good thing to note about the magnetic stirrer is that they are fully functional when exhibiting relevant task.
Applications
A magnetic stirrer can be used for different applications as well as tons of industries, with the food industry happening to be one of the places where it is widely being used. Another industry where it is has numerous uses is in the biotechnology industry. A magnetic stirrer can be used to mix samples of fluid.
What should be noticed In selection A magnetic stirrer?
-volume of fluid you’re stirring
-opening size and shape of vessel (container)
-size of internal drive magnet
-stir bar material construction
And now in detail:
Functions and features
It is important to write down in summary what you intend using the stirrer to achieve. For example, what are some of the jobs the stirrer would be used for? It is important to know the adequate unit and the size vessels. Plus, it is important to have an idea of the volume samples you intend to stir.
Also, you might want to answer if you would be using a computer or laptop to login data. The scale of your work also needs to be considered as well. Would certain features increase the efficiency? All these would give you a clue on getting the right magnetic stirrer.
Maintenance and Warranty
The next thing you might want to give serious consideration on is both the warranty and the maintenance of your product. If you intend to use the same unit for a considerable long time, then it is best recommended that you look for the one which has a strong warranty and is relatively inexpensive to purchase.
As you know all warranty comes with an expiration date, which is why you need to focus more on both the maintenance and the cost of service.
The Budget for choosing Magnetic Stirrer
When purchasing a lab equipment, it is always important to factor in the budget cost. While most individuals always place the budget above anything else, it is not a healthy mindset to condone. It is important to focus more on the unit and the effectiveness it carries rather than its price.
It would interest you to know that there are magnetic stirrers which come with a hot plate and there are others void of such. A magnetic stirrer with a hot plate would cost more than the one without.
Max. Permissible Temperature And humidity
It is always advisable to look at the max working temperature and humidity before making a purchase especially if you know fully well your lab is situated in tropical regions.
Mounting Surface Dimensions
It is always important to consider the mounting surface dimensions even though they are mostly mentioned in some technical data.
Magnetic stirrer: How it works
In order to effectively use a magnetic stirrer, the first line of action to take would be to place the bar magnet in a vessel that contains a liquid. Once that is achieved, the vessel would then have to be set in order to enable the bar magnet to rotate which in turn leads to the liquid being stirred. The reason why a magnetic stirrer is frequently being used in laboratory experiments is due to its small size.
The magnetic plates can be used in lots of firms. With the use of a magnetic stirrer, chemical experiments are being carried out with relative ease. It can be of great help in mixing together two components.
It is very much possible to mix a solution in a more convincing way especially when the magnetic field of the magnetic stirrer is being put to use. However, it is expected that you is placed in the stirrer before you start to stir. The moment the spinning process begins with the small bar magnet, you would notice an exterior magnetic field would be created. This small device isn't difficult to make use of in your laboratory. Plus, you can carry it from one location to another with relative ease. But, for the sake of safety, it is important that the right measures be put in place before carrying this stirrer.
Advantages
The following are some of the benefits that comes with the use of a magnetic stirrer.
1. They help in reducing the risk of contagion.
2. They help to reproduce a mixture
3. Makes stirring of samples easier.
