Stir plates will increase cell counts in yeast starters through continual aeration.
Does not include a stir bar.
Here's a brewing tool that will make your good beers better. Stir plates will increase cell counts in yeast starters through continual aeration. A stir bar rotates in the flask to create a vortex. This keeps the yeast in suspension and provides them with large amounts of oxygen. This helps you culture higher cell counts of healthy yeast for quicker fermentations, lower risk of infections and better tasting beer. All this in less time than it takes to make a conventional yeast starter.
You will also need a stir bar.
