Designed for stirring large volumes in vessels such as drums and tanks. A molded pivot ring minimizes the contact area between the bar and the vessel, thus reducing friction and chattering. Multifaceted surface adds turbulence relative to similar size smooth cylindrical stirring bars. Alnico magnet encapsulated in FDA Grade, USP Class VI Teflon® PTFE low friction coating. Autoclave safe.
