Spinring Magnetic Stirring Bars

Virtually Eliminates Spinout

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
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 Teflon® brand PTFE Coating – Superior Chemical Compatibility
Manufactured in a registered ISO 9001:2015 facility, as verified by SGS certification
Autoclave safe
