This stir plate is a great piece of equipment to add to your brewery tool chest if you are making yeast starters. The RPMs can be adjusted with the built in voltage regulator (aka the little knob on the front) to create a good looking vortex, but the power is limited in such a way that it won't "throw" the stir bar out of whack.
The unit measures 5 1/8 in. diameter which is large enough for a 2L (2000 mL) flask. Pairs great with some Proper Starter!
Tested to Ensure Quality
We've come across a lot of these economical stir plates in the past, and all of them have failed after a few uses. We put this new one to test though, and ran it non-stop for over two weeks and it never skipped a beat. In fact, it's still running on our show room floor! Tested by us to make sure that it works for you!
