The Stirstarter Yeast Stir Plate - Build a Yeast Starter

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 accommodate a 2000 mL flask . A Teflon coated 1" x 5/16" stir bar is included (2" stir bars are too long for this device, while we have had success using the 2" bar, it will be "thrown" from the magnet when the motor is at high speeds, "why would you turn your stir plate to higher speeds?" you ask. We aren't sure, but the coffee at McDonald's is hot whether the word "HOT" is printed on the cup or not). 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!
