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
  • Contains six stir bars, two each in the following sizes: 1 x 0.3125″ (25.4 x 8 mm), 1.5 x 0.3125″ (38.1 x 8 mm), 2 x 0.3125″ (50.8 x 8 mm)

Use this in combination with an Erlenmeyer Flask and Stir Plate to make a yeast starter.  A stir plate helps to keep yeast in constant contact with nutrients, encourages CO2 to off gas and continuously incorporates oxygen.  All of that means higher cell counts.
