Super-strong alnico V magnets remain coupled to drive magnets
One-piece coating of PTFE resists corrosion, heat, and cold
Chemically inert stir bars won't contaminate liquid being stirred
Guaranteed to be leakproof
Egg-shaped stir bars have oval magnets—ideal for use in round-bottom flasks. Shape conforms to flask bottom and ensures complete mixing. Low-friction PTFE coating ensures smooth spinning and maximum energy transfer.
