Cole-Parmer Egg-Shaped Stir Bar, 1-5/8" L x 3/4" Dia 1/Pk

Egg-shaped stir bars have oval magnets-ideal for use in round-bottom flasks. Shape conforms to flask bottom and ensures complete mixing. Super-strong Alnico V magnets remain coupled to drive magnets-resisting spin out at high stirring speeds. One-piece coating of PTFE resists corrosion, heat, and cold. Chemically inert stir bars won't contaminate the liquid being stirred and are guaranteed to be leak-proof. Low-friction PTFE coating ensures smooth spinning and maximum energy transfer.
