10 Pack of Stir Bars – $16.95 + Free Shipping, $1.70 Each

SEOH Magnetic Stir Bar Plain PTFE 6 x 25mm Pack of 6

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

Use along with an Erlenmeyer Flask and Stir Plate to do Stir Plate Yeast Starters.

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.
