This unit has two powerful NdFeB button magnets in the 12 VDC stir motor, which is controlled by a precision voltage regulator for easy speed adjustment. The RPMs of the drive motor are limited, so the motor will not "throw" the stir bar, yet it provides enough to get a good vortex going. A low voltage, plug-in wall transformer provides power to the unit. The black plastic case dimensions are 6" x 4" x 2", large enough to accomodate a 2000 mL flask as shown. A Teflon coated 1" x 5/16" stir bar is included. A "keeper" magnet is also supplied to lock the stir bar in place while the yeast is pitched, so the stir bar won't end up in your fermenter!
