Ode, The size of the stirrer in comparison with the surface of the
vessel, influences the amount of mass stirred and the turnover. When
defining magnetic stirrer's speeds, one should also include the the size
of the stirrer. for instance a 1/2 " magnet creates little turnover at
100 rpm. The same rpm with a 2" stirrer may spill the liquid.
Best regards

10-40 RPM works well. 100 might.
