Description
The PTFE Oval Stir Bars, also known as oval magnetic stirring bars for round bottom flasks, are designed for laboratory stirring applications where the vessel has a curved base. They are suitable for chemistry laboratories, teaching laboratories, preparation rooms, research laboratories and routine bench mixing workflows. The oval profile is intended for use in round bottom flasks, also known as boiling flasks. This shape helps the stir bar sit more naturally against the curved flask base compared with standard straight cylindrical bars.
The design supports stable rotation during magnetic stirring and helps reduce chatter during operation. This is useful where controlled mixing is required in compatible round bottom vessels. The stir bars are manufactured with PTFE construction, supporting chemical resistance with compatible solutions and reagents. The smooth PTFE surface also supports practical cleaning between uses during routine laboratory workflows. Available size options include L10 6 × 10, L20 8 × 20, L25 10 × 25, L30 11 × 30 and L40 15 × 40. Users should select the stir bar size according to flask volume, liquid viscosity, vessel shape and magnetic stirrer coupling strength.
These oval stir bars are suitable for general liquid mixing, solution preparation, reagent blending and supervised educational demonstrations. They should be used only with compatible vessels, suitable magnetic stirrers and appropriate laboratory procedures.
LabChoice Australia supplies PTFE Oval Stir Bars for school science laboratories, university teaching laboratories, chemistry laboratories, research facilities, quality-control areas and general laboratory workspaces. They are suitable for magnetic stirring in compatible round bottom flasks and boiling flasks where stable rotation and reduced chatter are required.
