I am doing yeast starters for home brew. For me it works perfectly with a 3000ml beaker. With yeast I shouldn’t do max RMP with my stir plate. All I need is slow and steady with a small vortex. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great little magnet *by L***A on April 18, 2020* Bought to stir liquid. Works great with magnetic stirrer. Well made.
