Call to Order
Octagon magnetic stirring bars with integral pivot ring are the most commonly used shape. Made of Alnico magnet encapsulated in FDA Grade, USP Class VI nonstick PTFE low friction coating. They are durable and inert. Their interrupted profile provides greater surface area and added turbulence when compared to the smooth surface of cylindrical bars. A pivot ring aids in reducing friction and chattering. Autoclavable, and manufactured in a registered ISO 9001 2008 department, as verified by SGS certification.
