Spinring® Magnetic Stirring Bar
By Bel Art Products
Spinring® stirring bars provide maximum stabilization of the magnetic stirring bar with the addition of a removable "hoop" around a standard octagonal bar. Best suited for larger open-neck vessels, such as buckets and beakers Friction fit of the "hoop" and bar allows them to spin as a unit. Spin out is virtually eliminated and the stirring bar remains centered in vessel. Octagon shape creates a deep vortex without splashing or chattering. Alnico magnet encapsulated in FDA Grade, USP Class VI PTFE low friction coating. Autoclave safe.
