Principle and Application of Water Bath Magnetic Stirrer

In scientific laboratories, various liquid mixing, reaction or dissolution operations are often required. As a common experimental instrument, the Water Bath magnetic stirrer provides experimental personnel with a convenient and efficient operation method. This article will introduce the working principle, application fields and operating techniques of the Water Bath magnetic stirrer, leading readers to have an in-depth understanding of this powerful tool in the laboratory.

working principle

Water bath magnetic stirrer is mainly composed of Water Bath, electromagnetic heating system, magnetic stirrer and temperature control system. First, the experimental liquid is poured into a Water Bath, and the temperature inside the Water Bath can be precisely controlled by an electromagnetic heating system. Then, place a magnetic stirrer bar at the bottom of the container, which will be attracted to the electromagnet underneath the Water Bath magnetic stirrer. When the Water Bath magnetic stirrer is turned on, the electromagnet generates a magnetic field, and the magnetic force acts on the stirrer, causing it to rotate at high speed in the liquid, thereby achieving stirring and mixing of the liquid. The temperature control system can monitor the temperature of the liquid in the Water Bath and automatically adjust the power of the electromagnetic heating system according to the set temperature value to keep the liquid temperature stable near the set value.

Application areas

Water bath magnetic stirrers are widely used in laboratories in chemistry, biology, drug research and development and other fields. In chemical experiments, it is often necessary to quickly dissolve solid samples or reagents in solvents, or to mix and react different reagents. Water bath magnetic stirrer can provide uniform stirring effect and accelerate the reaction process. Some chemical reactions need to be carried out at specific temperatures. The Water Bath magnetic stirrer can accurately control the temperature of the liquid in the Water Bath through the electromagnetic heating system to meet the temperature requirements of different reactions. In biological experiments, it is often necessary to prepare solutions or culture media. Water bath magnetic stirrers can provide uniform stirring during sample preparation, ensuring that solutions are evenly mixed. In biochemical experiments, such as enzyme reactions, cell culture and other operations, Water Bath magnetic stirrers can provide good stirring conditions for experiments and promote the progress of reactions.
