Yeast Starter Stir Plate

Looking for a brewing tool to take your home brewery to the next level? Try the StirStarter Yeast Starter Stir Plate! The StirStarter stir plate helps culture higher cell counts of healthy yeast for quicker fermentation, lower risk of infections and better tasting beer - all in less time than it takes to make a conventional yeast starter. Simply put the magnetic stir bar into the flask, and place it on the plate - the spinning magnets in the plate cause the stir bar to rotate, agitating the 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. 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! In order to grow more yeast in a shorter period of time the starter must be continually stirred. Stirred starters have a ten-fold increase in cell counts than a non-stirred starter because they aerate the wort which is essential for yeast to grow. Stirring keep the yeast in suspension and in constant contact with nutrients while ridding carbon dioxide which inhibits yeast growth.
