Magnetic stirring bars, PTFE, octagonal

magnetic stiirring bars with center rings and permanent magnet AlNiCo V core. The eight-sided shape gives rise to significant turbulence, and thus achieves effective mixing, even at low spin rates. The middle ring also promotes stable centering with convex or uneven bottoms.
