Bel-Art Spinbar Teflon Octagon Magnetic Stirring Bar; 28.6 x 8mm, White (F37110-0118)

Octagonal shape creates more turbulence and a stronger vortex than a round, cylindrical shape or a polygonal shape

Teflon (PTFE) casing is chemically inert, can be used with corrosive chemicals, and helps reduce friction and wear while spinning

Built-in pivot ring helps reduce vibration and wear during stirring

Internal magnet made from alnico V, an alloy of aluminum, nickel, iron, and cobalt

Casing material is FDA approved for use in food, drug, and cosmetic applications

Octagon magnetic stirring bars with integral pivot ring are the most commonly used shape. Their interrupted profile provides greater surface area and added turbulence when compared to the smooth surface of cylindrical bars. Pivot ring aids in reducing friction and chattering. Coated in white PTFE. Dimensions: 28.6 x 8mm (1-1/8 x 5/16").
