Hanna HI200 Magnetic Stirrer
Hanna HI200M Magnetic Stirrer
Compact size - The compact size of this stirrer allows users to maximize bench space for efficiency and safety.
Safety - Speedsafe™ limits the maximum speed to 1000 rpm even if a load is suddenly removed.
Built to last - The stainless steel of HI 200M resists most harmful chemicals in the lab.
The HI 200M is compact and lightweight, so that lack of laboratory bench space is no longer a concern.
This stirrer incorporates electronic controls that allow the user to regulate the speed with greater precision. Often, in the lab, a sample is removed from the stirrer before reducing the speed. This would cause the motor of conventional equipment to accelerate until it is destroyed. This does not pose a problem with HANNA mini-stirrers. In fact, the internal Speedsafe™ mechanism will ensure that the maximum speed is never exceeded.

A device that employs a rotating magnetic field to cause a stir bar immersed in a liquid to spin very quickly, thus stirring it.
Why is a magnetic stirrer better then a motorized stirrer? Because they are quieter, more efficient, and have no moving external parts to break or wear out. Due to its small size, a stirring bar is more easily cleaned and sterilized than other stirring devices. They do not require lubricants which could contaminate the reaction vessel and the product.
