Description
The PTFE Octahedral Stir Bar, also known as an octahedral magnetic stirring bar, is designed for general laboratory stirring where increased turbulence is needed at lower stirring speeds. It is suitable for chemistry laboratories, teaching laboratories, preparation rooms, research laboratories and routine bench mixing applications. The stir bar has a stated size of 5.5 × 42 mm, making it suitable for compatible vessels where a longer magnetic stirring accessory is required. Users should match the stir bar length to the vessel diameter, liquid volume and magnetic stirrer strength for controlled operation.
The octahedral profile is described as similar to the pivot ring type but designed to create more turbulence at low speed. This makes it useful for applications where agitation is required without increasing the stirring speed excessively. The low-speed turbulence effect can support mixing of compatible liquids where standard stir bars may produce limited movement at lower rpm. Users should adjust the speed gradually to maintain stable coupling and prevent unnecessary splashing or bar movement. The PTFE construction supports chemical resistance with compatible solutions and reagents. It also provides a smooth surface for practical cleaning between uses, supporting routine laboratory workflows where stir bars are reused across different mixing tasks.
LabChoice Australia supplies PTFE Octahedral Stir Bars for school science laboratories, university teaching laboratories, chemistry laboratories, research laboratories, quality-control areas and general laboratory workspaces. They are suitable for magnetic stirring, solution preparation, reagent blending and low-speed agitation using compatible vessels, magnetic stirrers and supervised laboratory procedures.
