Mono-Mold Standard Stir Bar with Spinning Ring, 1-1/2"L x 3/8" Dia

Mono-Mold magnetic stir bars are the standard all-purpose stir bar. Available with or without spinning Rings; Rings reduce contact area between stir bar and vessel, reducing friction and noise. Super-strong Alnico V magnets remain coupled to drive magnets—resisting "spin-ou" at high speeds. Chemically inert, low-friction, leak-proof PTFE coating provides smooth spinning and maximum energy transfer.
