Now in its sixth generation, the U.S. made EZ-Stir Plate is the most powerful stir plate we sell, and will stir 1000 to 5000ml of starter solution. This sturdy unit is 7.25" wide, and 1.5" tall, and will easily accomodate heavy 5000ml flasks. A 1" stir bar is included.
This unit has a 12 volt stir motor, which is controlled by a precision voltage regulator for speed adjustment. The RPMs of the drive motor are limited, so the motor will not “throw” the stir bar (unless you turn it up too high or move the starter once it has started), yet it provides enough to get a good vortex going. A low voltage, plug-in wall transformer provides power to the unit. Instructions included.
Good little value stir plate. Be aware though that it seems to throw off heat which is absorbed into the starter. Starter was several degrees above ambient the whole time. Some is due to fermentation, sure. But not that much. I just chuck the whole set up in my temp controlled fermenter.
This product broke down immediately upon using. I would not get it, rather try for a replacement.
William's Brewing Responds: We have not heard from you. Did you take advantage of the one year warranty?
works as advertised, I've used it 4 times already and it runs for days with no problems. It can create a powerful vortex even with the 1" stir bar. (you don't need to do that for starters though, just for fun)
