Round, cylindrical shape with smooth profile and removable ring (use as cylindrical or pivot ring). Fluid, steady action. Features excellent centering and even running characteristics. Removable ring adds versatility. Use with or without ring. Ring minimizes contact area and aids in reducing friction and lessening marring (of plastic containers). Ideal for highly effective mixing over a wide variety of conditions, including general purpose stirring. PTFE stirring bars offer ultimate performance, long working life, and extreme versatility. PTFE coating features chemical resistance, thermal stability, low friction (with little or no adhesion), and insolubility (with high purity). Inert and leak-free. Isostatic encapsulation to eliminate cracks and porosity. Polished finish to reduce pickup and cross contamination. Can be sterlized via all typical chemical or thermal (i.e., autoclave, etc.) means (except gamma radiation). FDA and USP Class VI approved PTFE (polytetrafluoroethylene). Pure PTFE coating. AlNiCo V magnet core. Various dimensions and weights. See dropdown options to select size.
