Description
The PTFE Cross Stir Bar, also known as a cross-shaped magnetic stirring bar, is designed for general purpose magnetic stirring in laboratory and educational environments. 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 38 × 38 mm, making it suitable for compatible vessels where a stable magnetic stirring accessory is required. Users should match the stir bar size to the vessel diameter, liquid volume and magnetic stirrer strength for controlled operation.
The cross profile is designed to provide extra stability on the vessel base during stirring. This helps reduce jumping, chatter and loss of coupling, especially where a standard cylindrical stir bar may become unstable at higher speeds or during turbulent mixing. 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.
This stir bar is suitable for general liquid mixing, solution preparation, reagent blending and routine laboratory stirring where improved stability is useful. Users should confirm chemical compatibility, vessel fit and operating speed before use.
LabChoice Australia supplies PTFE Cross Stir Bars for school science laboratories, university teaching laboratories, chemistry laboratories, research laboratories, quality-control areas and general laboratory workspaces. They are suitable for stable magnetic stirring of compatible liquids using appropriate vessels, magnetic stirrers and supervised laboratory procedures.
