From the product description, check product page for current description, price and availability:

  • Octagonal shape creates more turbulence and a stronger vortex than a round, cylindrical shape or a polygonal shape
  • Teflon (PTFE) casing is chemically inert, can be used with corrosive chemicals, and helps reduce friction and wear while spinning
  • Built-in pivot ring helps reduce vibration and wear during stirring
  • Internal magnet made from alnico V, an alloy of aluminum, nickel, iron, and cobalt
  • Casing material is FDA approved for use in food, drug, and cosmetic applications

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.
