Magnetic Stirrers and their Applications
Magnetic stirrers are used to prepare mixtures by the use of an electronic motor. They are silent and can stir closed systems without being set apart. Due to their size, the bars can be cleaned and sterilized compared to other rods.
Most of the chemical reactions are performed in beakers found in laboratories, and the stirring bar is coated with glass, and their sizes may vary to enhance efficiency when stirring. The glass coating also prevents chemical reactions that can contaminate the reaction. The magnetic stirrer has a capacity of four liters or less since they are used for small experiments. The primary function of the stirrer is speeding up the rate of the reaction, and it is often used with hot plates.
Applications of Magnetic Stirrers
They are commonly used for experiments in chemistry and biology, especially when you need to mix components to come up with a uniform mixture. The stirring equipment allows variable speed depending on the requirements of the experiment. It is commendable to use a gentle stirring to avoid damage to the cells.
Magnetic stirrers are used in the extraction of plants to increase efficiency in the process. They use a rotating magnetic field that forces the stir bar to mix the substances in the extraction process. The stirrer can achieve a high rate of reaction in the shortest possible time. The size of the stirring bar varies in length depending on the requirements of the experiment.
It is commendable to understand the functions and uses of magnetic stirrers before using them for your project. You can get in touch with experts in laboratory equipment who are well adept with all tools used in biological experiments. They give you knowledge and insight on stirring systems and help you avoid any mistakes in your choice of apparatus.
It is advisable to choose the proper apparatus that best suits your needs. It would help considering the container size, the material of the bar, and the volume of the liquid.
