6 Pack of Magnetic Stir Bars by SEOH.  PTFE 6 x 25 mm (about an inch).

Why a Stir Plate? The constant motion of a stir plate integrates oxygen, puts yeast in constant contact with nutrients, relieves built up CO2 and generally helps yeast to grow more rapidly.  That also means smaller starters.

I have this stir bar and it works great.  DIY Stir PlateThe vortex to the right was created with the help of this stir bar.  See: The HBF Stir Plate Mounting-Thingy for more info.

StirStarter Stir Plate – $42 + Free Shipping

StirStarter Stir Plate eBay

More Info

From the description…

“Here’s good news for all you beer home brewers. YOU don’t make beer; your one-celled friends called yeast do all the work! That’s why happy, healthy yeast is the cornerstone of good brewing practice. You can make sure your yeast is ready for action in the fermenter with a magnetic stir plate. I built one and like it so much I have decided to build more and sell them to the home brewing community at a fair price. I call my version the StirStarter.

Home brewing discussion forums are full of details on how to make your own stir plate with used spare parts like hard drive magnets, computer fans and old cigar boxes. It’s a fun weekend project and if you’re mechanically inclined it might even work!

But if you’re not ready to invest the time and effort to build and perhaps troubleshoot your own creation, let me do the job for you. I am a registered professional electrical engineer and I have spent many hours improving the design of the StirStarter. My eBay seller status, 100% positive feedback and obsession with customer service means you can buy with confidence!

The StirStarter comes complete with stir bar, operating instructions and a “keeper” magnet to lock the stir bar in place so it won’t end up in your fermenter when the yeast is pitched!

For detailed product specifications, yeast starter info and helpful construction hints if you want to build your own, do a Google search on the word StirStarters.

The StirStarter will be shipped via Priority Mail after the receipt of your order. The StirStarter is guaranteed forever. If it fails to perform for ANY reason, ship it back to me for repair or replacement at no charge.”

 

As of this posting, this great stir plate is selling for just $42.  Expedited shipping is free to most US addresses.  Check the offering description for up to the minute price and availability.
