Egg-Shaped Stir Bar, 13/16" L x 3/8" 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 leakproof. Low-friction PTFE coating ensures smooth spinning and maximum energy transfer.
