Laboratories handle a large number of experiments daily. The usual procedure involves the mixing of sample combinations. A key chemical principle involved in the process is exothermic energy. When two chemical substances react to form another compound, energy (exothermic) is released. The procedure of giving it the required energy is called endothermic energy. When the sample substances are highly reactive or corrosive, this exothermic energy can only be dealt with by constant stirring. This is where magnetic stirrers and stirring systems replace the process of manual stirring. The magnetic systems ensure that the technicians aren’t subjected to any risk of burns due to uncontrolled conditions and hence, provide an easier and safer environment for them.
How does it work?
The working principle of magnetic stirrers and stirring systems usually involves a stir bar that is immersed in the liquid solutions chosen for experimentation. This vessel then is placed upon a hotplate magnetic stirrer, the temperature and speed of which can be directly controlled by the technician. This then generates a rotating electromagnetic field that interferes with the stir bar to induce stirring movement and form a homogenous solution. Another system involves a submersible stirrer where the stirrer is immersed inside the liquid while its battery case remains outside.
