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, leakproof PTFE coating provides smooth spinning and maximum energy transfer
