While there are certainly cheaper magnetic stir plates on the market, and we have used them, they have a homemade quality and feel. This unit is professionally made by Hanna and you will not be disappointed with the quality. This unit is protected by a fuse.Stir plates will increase cell counts in your starters through continual aeration. A teflon coated stir bar (included) rotates in the flask to create a vortex. This keeps the yeast in suspension and provides them with large amounts of oxygen. Leave the starter on the stir plate for the duration of the starter. The INCLUDED stir bar can be boiled with the starter to sanitize.
We recommend picking up an extra stir bar as they can easily be poured right into the fermenter and then forgot about when you are cleaning out the fermenter.
