Description
Oval magnet 70 × 20 mm – egg-shaped PTFE-coated stir bar
Egg-shaped stir bar for magnetic stirrers, 70 × 20 mm. The magnet core is Alnico V coated with PTFE, which gives a smooth surface and high chemical resistance. The egg shape is designed for round-bottom flasks.
Brewers use a magnetic stirrer and stir bar when making a yeast starter. The stir bar keeps the liquid moving, so the yeast gets oxygen and multiplies.
