• Polygonal shape is smoother than an octagonal shape and creates more turbulence and a stronger vortex than a round, cylindrical shape
• Teflon (PTFE) casing is chemically inert, can be used with corrosive chemicals, and helps reduce friction and wear while spinning
• Smooth surface provides quicker cleanup and less risk of cross-contamination than bars with pivot rings and allows the bar to spin on the bottom of the container to disperse light sediment and air bubbles
• Internal magnet made from alnico V, an alloy of aluminum, nickel, iron, and cobalt
• For stirring large volumes of liquid in containers with a neck diameter of 32 mm and larger
