I think that it is suitable for 50 ml, 100 ml beaker. I think that it can be used even in a 200 ml beaker. When it becomes 300 ml beaker or more, stirring efficiency will increase for 40 mm length and 50 mm length. However, if the length is too close to the diameter of the beaker, the rotation will not be smooth and the stirring efficiency will be lower, so be careful.
Used for stirring in brine electrolysis beaker test

As a electrolytic cell, we used a 7 L aquarium for goldfish polystyrol. Set the temperature to 50 ° C and stir with a 8φ X 50 L rotor. It was confirmed that the fine bubbles (hydrogen and oxygen) generated in the electrode were dispersed throughout and well agitated. However, after the end of the experiment, a circle of concentric circle scratches was formed at the position where the rotor at the bottom of the container was rotating. It is not the rotor's responsibility because the material of the aquarium is a problem, but it was the point I noticed. For example, it may be good to lay a "cushion" under the rotor.
Although there is no problem with respect to magnetic force, the coating on the surface was easily scraped off during the use process, and this floating material was generated in the water and I was in trouble.
