A magnetic stirrer plays key role in minimizing the risk of contamination since there is only an inert magnet bar that is placed inside the sample (fluid). It is very easy to keep this device clean. A manual stirrer is different from the magnetic one. The magnetic stirrer is vital for the process of reproducible mixing or mixing for extended period. In the case where you require the process of protein dialysis to be performed on a sample, you will be required to place the sample in the stirrer for a very long time. In fact, many laboratories prefer overnight sample mixing thus enabling them to utilize valuable time. This would be possible only with a Magnetic Stirrer and not the manual kind.
There are many types of Magnetic Stirrer available like the heavy duty magnetic stirrer, the battery powered magnetic stirrer and even the air operated turbine magnetic stirrer. Each has unique characteristics and applications.
Magnetic stirrers are often used in chemistry and biology, where they can be used inside hermetically closed vessels or systems, without the need for complicated rotary seals. They are preferred over gear-driven motorized stirrers because they are quieter, more efficient, and have no moving external parts to break or wear out (other than the simple bar magnet itself). Magnetic stir bars work well in glass vessels commonly used for chemical reactions, as glass does not appreciably affect a magnetic field. The limited size of the bar means that magnetic stirrers can only be used for relatively small experiments, of 4 liters or less. Stir bars also have difficulty in dealing with viscous liquids or thick suspensions. For larger volumes or more viscous liquids, some sort of mechanical stirring is typically needed.
