Description
The PTFE Smooth Stir Bars, also known as smooth cylindrical magnetic stirring bars, are designed for general purpose magnetic stirring in laboratory and educational environments. They are suitable for chemistry laboratories, school science laboratories, university teaching laboratories, preparation rooms, research laboratories and routine bench mixing workflows. The smooth cylindrical profile supports stable stirring in compatible flat-bottom vessels. This makes the range suitable for everyday liquid mixing where a simple, reliable magnetic stir bar is required.
These stir bars are designed to support smooth mixing and consistent magnetic coupling with a compatible magnetic stirrer. Their profile helps reduce chatter during routine operation when the correct bar size, vessel size, liquid volume and stirring speed are selected. The PTFE construction supports chemical resistance with compatible solutions, reagents and buffers. The smooth surface also supports practical cleaning between uses, making the stir bars suitable for repeated laboratory workflows.
Available sizes include Z10 5 × 10, Z15 8 × 15, Z20 7 × 20, Z25 8 × 25, Z30 8 × 30, Z40 8 × 40 and Z50 8 × 50. Users should select the bar length and diameter according to vessel size, sample volume, viscosity and stirrer drive strength. These smooth stir bars are suitable for general liquid mixing, solution preparation, reagent blending, buffer preparation and supervised educational demonstrations. They should be used only with compatible vessels, suitable magnetic stirrers and appropriate laboratory procedures.
LabChoice Australia supplies PTFE Smooth Stir Bars for school science laboratories, university teaching laboratories, chemistry laboratories, research facilities, quality-control areas and general laboratory workspaces. They are suitable for routine magnetic stirring where smooth operation, stable coupling and easy cleaning are required.
