<b>[Product Information]</b><br>
<ul>
<li>Octagonal shape with fluted ends provides more turbulence than a non-fluted octagonal stir bar and can be used with containers with curved bottoms</li>
<li>Teflon (PTFE) casing is chemically inert, can be used with corrosive chemicals, and helps reduce friction and wear while spinning</li>
<li>Spins on the bottom of the container to disperse sediment and air bubbles</li>
<li>Internal magnet made from samarium cobalt provides stronger magnetic attraction in viscous solutions and at high speeds than a magnet made from an alloy of alnico V</li>
<li>Green color for quick identification</li>
</ul>
