6 Pack of PTFE Stir Bars by Bel-Art. Octagonal shape to create more turbulence and stronger vortex vs round, cylindrical shape or a polygonal shape stir bars. PTFE casing. Built-in pivot ring helps reduce vibration and wear during stirring. 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… keeps yeast in constant contact with nutrients, encourages CO2 to off gas and continuously incorporates oxygen. All of that means higher cell counts.
